BOOL ActivateGadget(
struct Gadget * gadget,
struct Window * window,
struct Requester * requester );
Activates the specified gadget.
gadget - The gadget to activate
window - The window which contains the gadget
requester - The requester which contains the gadget or
NULL if it is not a requester gadget
void ActivateWindow(
struct Window * window );
Activates the specified window. The window gets the focus
and all further input is sent to that window. If the window
requested it, it will get a IDCMP_ACTIVEWINDOW message.
window - The window to activate
If the user has an autopointer tool (sunmouse), the call will
succeed, but the tool will deactivate the window right after
this function has activated it. It is not a good idea to try to
prevent this by waiting for IDCMP_INACTIVEWINDOW and activating
the window again since that will produce an annoying flicker and
it will slow down the computer a lot.
ModifyIDCMP() OpenWindow() CloseWindow()
void AddClass(
struct IClass * classPtr );
Makes a class publically usable. This function must not be called
before MakeClass().
class - The result of MakeClass()
Do not use this function for private classes.
There is no protection against creating multiple classes with
the same name yet. The operation of the system is undefined
in this case.

UWORD AddGadget(
struct Window * window,
struct Gadget * gadget,
ULONG position );
Adds a single gadget to a window.
window - Add gadget to this window
gadget - Add this gadget
position - The position to add the gadget in the list of
gadgets already in the window. Use 0 to insert the
gadget before all others or ~0 to append it to the
The position where the gadget was really inserted.
This just adds the gadget to the list. It will not be visible
until you refresh the window.
UWORD AddGList(
struct Window * window,
struct Gadget * gadget,
ULONG position,
LONG numGad,
struct Requester * requester );
Add some gadgets to a window.
window - Add gadgets to this window
gadget - This is the list of gadgets to add
position - Where to insert the gadgets in the list of gadgets
already in the window. Use 0 to insert the gadgets
before all others in the window or ~0 to append them.
numGad - How many gadgets of the list should be added.
Use -1 to add all gadgets in the list.
requester - Pointer to the requester structure if the window is
a requester.
The actual position where the gadgets were inserted.
The gadgets will just be added. To make them visible, you must
refresh the window or the gadgets.

APTR AllocRemember(
struct Remember ** rememberKey,
ULONG size,
ULONG flags );
Allocate some memory and remember it in the Remember-List.

FreeRemember(&remkey, TRUE);
struct ScreenBuffer * AllocScreenBuffer(
struct Screen * screen,
struct BitMap * bitmap,
ULONG flags );
Allocate a ScreenBuffer (and BitMap) for double or multiple
buffering in Intuition screens. Use this function to obtain a
ScreenBuffer for the screen's initial BitMap and for all other
BitMaps you want to swap in.
This function also allocates a DBufInfo from graphics.library
The returned ScreenBuffer contains a pointer to that DBufInfo.
See graphics.library/AllocDBufInfo() for more information on
how to use this struct to obtain info when it is safe to render
into an old buffer and when to switch.
screen - Screen to double-buffer
bitmap - You may pre-allocate a BitMap for CUSTOMBITMAP screens,
and pass the pointer to get a ScreenBuffer referring to it.
If you specify NULL, intuition will allocate the BitMap for
you. For non-CUSTOMBITMAP screens this parameter must be NULL.
flags - A combination of these flags:
SB_SCREEN_BITMAP for non-CUSTOMBITMAP screens to get a
ScreenBuffer referring to the screen's actual BitMap
(For CUSTOMBITMAP screens just pass the BitMap you used for
OpenScreen() as the bitmap parameter)
SB_COPY_BITMAP to copy the screen's BitMap intto the
ScreenBuffer's BitMap. Use this to get intuition rendered
stuff into your bitmap (such as menu-bars or gadgets).
May be omitted if the screen has no intuition rendered stuff,
as well as for allocating a ScreenBuffer for the screen's
initial BitMap.
Pointer to the allocated ScreenBuffer or NULL if function failed.
You may render into the resulting BitMap.
Use the sb_DBufInfo field to access graphics.library's ViewPort
buffering features to e.g check if it is safe to reuse the previous
BitMap. Otherwise you risk to write into the on-screen BitMap and
damage menu or gadget rendering.

void AlohaWorkbench(
struct MsgPort * wbmsgport );
The WorkBench program wants to call this function to signal
Intuition that it is active or shutting down.
Intuition then uses the MsgPort to tell the WorkBench to open or
close its windows if the user called OpenWorkbench() or
When the MsgPort is non-NULL Intuition will send IntuiMessages to
it with the Class field set to WBENCHMESSAGE and Code field set to
either WBENCHOPEN or WBENCHCLOSE. Intuition assumes that when the
WorkBench task replies this messages, it already has opened/closed
its windows.
wbmsgport - The MsgPort of the (initialized) WorkBench task or
NULL if the task is shutting down.
This function is obsolete and should not be used directly by the

notify applications that the UI will be changed.
This function is private and AROS-specific. Do not use it in regular
ULONG ChangeScreenBuffer(
struct Screen * screen,
struct ScreenBuffer * screenbuffer );
Do double or multiple buffering on an intuition screen in an
intuition-cooperative way. The ScreenBuffer's BitMap will be
installed on the specified screen, if possible. After a signal from
graphics.library, the previously installed BitMap will be available
for re-use. Consult graphics.library/AllocDBufInfo() and
graphics.library/ChangeVPBitMap() for further information.
screen - The screen this screenbuffer belongs to
screenbuffer - The screenbuffer obtained by AllocScreenBuffer()

BOOL DisplayAlert(
ULONG alertnumber,
UBYTE* string,
UWORD height );
Bring up an alert with the given message.
alertnumber - Value determining type of alert. For historical reasons,
this is the same value as passed to Alert(). However,
this functions takes into account only AT_DeadEnd bit.
string - A pointer to text data. Text data have the following layout:
each string is preceded by 3 bytes. The first two of them are
the X coordinates of the string in the alert display. This is
given as a big-endian value. The third byte is the Y
coordinate of the text's baseline. Then a NUL-terminated
string follows by itself. After the NUL terminator there's
one more byte. If it's not zero, another string starts from
the next byte. Zero marks the end of the sequence. The text
is always rendered using the topaz/8 font.
height - The height of alert display in pixels.
Always FALSE if AT_DeadEnd bit is set in alertnumber. Otherwise the
function returns TRUE or FALSE depending on what user chooses. In
AROS, alerts are presented in a requester with two gadgets: Ok and
Cancel. Ok returns TRUE; Cancel returns FALSE.
If the alert could not be posted for whatever reason, FALSE is
This function is obsolete and exists only for backwards compatibility
with AmigaOS(tm). On various modern systems this function has
different effects. On classic Amiga(tm) this function may not work
with RTG displays, so it is generally deprecated. Please don't use it
in new software! Use legitimate intuition requesters if you want to
present some message to the user.

BOOL FreeClass(
struct IClass * iclass );
Only for class implementatores.
Tries to free a class which has been created with MakeClass() in the
first place. This will not succeed in all cases: Classes which
still have living objects or which are still being used by subclasses
can't simply be freed. In this case this call will fail.
Public classes will always be removed with RemoveClass() no matter
if FreeClass() would succeed or not. This gurantees that after the
call to FreeClass() no new objects can be created.
If you have a pointer to allocated memory in cl_UserData, you must
make a copy of that pointer, call FreeClass() and if the call
succeeded, you may free the memory. If you don't follow these rules,
you might end up with a class which is partially freed.
iclass - The pointer you got from MakeClass().
FALSE if the class couldn't be freed at this time. This can happen
either if there are still objects from this class or if the class
is used a SuperClass of at least another class.
TRUE if the class could be freed. You must not use iclass after

Frees a ScreenBuffer allocated by AllocScreenBuffer() and releases
associated resources. You have to call this before closing your
screen - The screen this screenbuffer belongs to
screenbuffer - The screenbuffer obtained by AllocScreenBuffer().
It is safe to pass NULL.
When used SB_SCREEN_BITMAP on allocating the ScreenBuffer
(ie. the ScreenBuffer only refers to the screen's BitMap) you must
FreeScreenBuffer() the ScreenBuffer before closing the screen.
Intuition will recognize when FreeScreenBuffer() is called for the
currently installed ScreenBuffer that it must not free the BitMap.
This is left to the CloseScreen() function.

information can get it in a cleaner way. It is recommended not to
call this function!
ULONG GetAttr(
ULONG attrID,
Object * object,
IPTR * storagePtr );
Asks the specified object for the value of an attribute. This is not
possible for all attributes of an object. Read the documentation for
the class to find out which can be read and which can't.
attrID - ID of the attribute you want
object - Ask the attribute from this object
storagePtr - This is a pointer to memory which is large enough
to hold a copy of the attribute. Most classes will simply
put a copy of the value stored in the object here but this
behaviour is class specific. Therefore read the instructions
in the class description carefully.
Mostly TRUE if the method is supported for the specified attribute
and FALSE if it isn't or the attribute can't be read at this time.

drawInfo - an object pointer to query. It is possible to set this
argument to NULL when querying GDIA_Color or GDIA_Pen
attributes. In this case values will be retrieved from
system preferences.
attrID - ID of the attribute you want. The following IDs are
currently defined:
GDIA_Color - 0RGB value of the color corresponding to a given pen.
It is possible to retrieve these values only from
DrawInfos belonging to direct-color screens. Pen ID
should be ORed with attribute ID.
GDIA_Pen - LUT color number corresponding to a given pen.
GDIA_Version - Version number of the DrawInfo object.

LONG GetScreenData(
APTR buffer,
ULONG size,
ULONG type,
struct Screen * screen );
Copy part or all infos about a screen into a private buffer.
To copy the Workbench, one would call
GetScreenData (buffer, sizeof(struct Screen), WBENCHSCREEN, NULL)
If the screen is not open, this call will open it. You can use
this function for these purposes:

Returns the address of the menuitem 'menunumber' of 'menustrip'.
The number is the one you get from intuition after the user has
selected a menu.
The menunumber must be well-defined.
Valid numbers are MENUNULL, which makes the routine return NULL,
or valid item number of your menustrip, which contains
- a valid menu number
- a valid item number
- if the menu-item has a sub-item, a valid sub-item number
Menu number and item number must be specified. Sub-item, if
available, is optional, therefore this function returns either
the item or sub-item.
menustrip - Pointer to the first menu of the menustrip.
menunumber - Packed value describing the menu, item and if
appropriate sub-item.
Returns NULL for menunumber == MENUNULL or the address of the
menuitem described by menunumber.
void LendMenus(
struct Window * fromwindow,
struct Window * towindow );
This function "lends" the menus of one window to another. This makes
the menu events (e.g. menu button presses) take place in another
window's menu (i.e. the other window's strip and screen).
This function is used to unify two windows on different attached
screens. (E.g. a painting program with an attached palette screen
can open the menu on the main screen if the menu button is
pressed on the palette screen.)
fromwindow - This window's menu events will go to another window.
towindow - This is the window that will react on the menu actions
of the other window. If NULL 'lending' will be turned off.
SetMenuStrip() ClearMenuStrip()
ULONG LockIBase(
ULONG What );
Locks Intuition. While you hold this lock, no fields of Intuition
will change. Please release this as soon as possible.
What - Which fields of Intuition should be locked. The only allowed
value for this is currently 0 which means to lock everything.
The result of this function must be passed to UnlockIBase().
You *must not* call this function if you have any locks on other
system resources like layers and LayerInfo locks.
void lockPubClass();
Locks the public classes list.
struct Screen * LockPubScreen(
CONST_STRPTR name );
Locks a public screen, thus preventing it from closing. This is
useful if you want to put up a visitor window on a public screen
and need to check some of the public screen's fields first -- not
locking the screen may lead to the public screen not existing when
your visitor window is ready.
If you try to lock the Workbench screen or the default public screen
and there isn't any, the Workbench screen will be automatically opened
and locked.
name - Name of the public screen or NULL for the default public
screen. The name "Workbench" refers to the Workbench screen.
The name is case insensitive.
A pointer to the screen or NULL if something went wrong. Failure can
happen for instance when the public screen is in private state or
doesn't exist.
To open a visitor window which needs information from the screen
structure of the public screen to open on, do this:
if((pubscreen = LockPubScreen("PubScreentoOpenon")) != NULL)
...check pubscreen's internal data...
OpenWindow(VisitorWindow, pubscreen);
UnlockPubScreen(NULL, pubscreen);
...use your visitor window...
You don't need to hold the lock when your visitor window is opened as
the pubscreen cannot be closed as long as there are visitor windows
on it.
OpenWindow() UnlockPubScreen() GetScreenData()
struct List * LockPubScreenList();
Arbitrates access to the system public screen list. This is for Public
Screen Manager programs only! The list should be locked for as short a
time as possible.
The list's nodes are PubScreenNodes as defined in
struct IClass * MakeClass(
ClassID classID,
ClassID superClassID,
struct IClass * superClassPtr,
ULONG instanceSize,
ULONG flags );
Only for class implementators.
This function creates a new public BOOPSI class. The SuperClass
should be another BOOPSI class; all BOOPSI classes are subclasses
of the ROOTCLASS.
SuperClasses can by private or public. You can specify a name/ID
for the class if you want it to become a public class. For public
classes, you must call AddClass() afterwards to make it public
The return value contains a pointer to the IClass structure of your
class. You must specify your dispatcher in cl_Dispatcher. You can
also store shared data in cl_UserData.
To get rid of the class, you must call FreeClass().
classID - NULL for private classes otherwise the name/ID of the
public class.
superClassID - Name/ID of a public SuperClass. NULL is you don't
want to use a public SuperClass or if you have the pointer
your SuperClass.
superClassPtr - Pointer to the SuperClass. If this is non-NULL,
then superClassID is ignored.
instanceSize - The amount of memory which your objects need (in
addition to the memory which is needed by the SuperClass(es))
flags - For future extensions. To maintain comaptibility, use 0
for now.
Pointer to the new class or NULL if
- There wasn't enough memory
- The superclass couldn't be found
- There already is a class with the same name/ID.
No copy is made of classID. So make sure the lifetime of the contents
of classID is at least the same as the lifetime of the class itself.
LONG MakeScreen(
struct Screen * screen );
Create viewport of the screen.
Pointer to your custom screen.
Zero for success, non-zero for failure.
RemakeDisplay() RethinkDisplay() graphics.library/MakeVPort().
BOOL ModifyIDCMP(
struct Window * window,
ULONG flags );
This routine modifies the state of your window's IDCMP (Intuition
Direct Communication Message Port).
Depending on the current state in the IDCMPFlags of the window and
the specified flags these actions are possible:
IDCMP flags Action
0 0 Nothing happens.
0 !=0 The flags are copied in the IDCMPFlags of the window
and a MessagePort is created and stored in the
UserPort of the window.
!=0 0 The IDCMPFlags are cleared and the MessagePort in the
UserPort is deleted.
!=0 !=0 The flags are copied to the IDCMPFlags of the
window - The window to change the IDCMPFlags in.
flags - New flags for the IDCMPFlags of the window. See
intuition/intuition.h for the available flags.
TRUE if the change could be made and FALSE otherwise.
You can set up the Window->UserPort to any port of your own
before you call ModifyIDCMP(). If IDCMPFlags is non-null but
your UserPort is already initialized, Intuition will assume that
it's a valid port with task and signal data preset and Intuition
won't disturb your set-up at all, Intuition will just allocate
the Intuition message port half of it. The converse is true
as well: if UserPort is NULL when you call here with
IDCMPFlags == NULL, Intuition will deallocate only the Intuition
side of the port.
This allows you to use a port that you already have allocated:
- OpenWindow() with IDCMPFlags equal to NULL (open no ports)
- set the UserPort variable of your window to any valid port of your
own choosing
- call ModifyIDCMP with IDCMPFlags set to what you want
- then, to clean up later, set UserPort equal to NULL before calling
CloseWindow() (leave IDCMPFlags alone) BUT FIRST: you must make
sure that no messages sent your window are queued at the port,
since they will be returned to the memory free pool.
For an example of how to close a window with a shared IDCMP,
see the description for CloseWindow().
Intuition v50 features a WA_UserPort tag, which allows to set
the UserPort at OpenWindow stage. Please note that using this tag
changes the behaviour of ModifyIDCMP() slightly. Creating/disposing
message ports is now up to the app. ModifyIDCMP(win,0) still clears
win->UserPort pointer, but the message port is NOT disposed - you
need to store it and dispose yourself! Also calling
ModifyIDCMP(win,someidcmp) on a window with NULL win->UserPort will
NOT create a new port!

vertPot - New value for the VertPot field of the PropInfo
horizBody - New value for the HorizBody field of the PropInfo
vertBody - New value for the VertBody field of the PropInfo
This function causes all gadgets from this gadget to the end of
the gadget list to be refreshed. If you want a better behaviour,
use NewModifProp().
void MoveScreen(
struct Screen * screen,
LONG dx,
LONG dy );
Move a screen by the specified amount in X/Y direction. The
resolution is always the screen resolution.
screen - Move this screen
dx - Move it by this amount along the X axis (> 0 to the right,
< 0 to the left).
dy - Move it by this amount along the Y axis (> 0 down, < 0 up)
Depending on other restrictions, the screen may not move as far
as specified. It will move as far as possible and you can check
LeftEdge and TopEdge of the screen to see how far it got.
void MoveWindow(
struct Window * window,
LONG dx,
LONG dy );
Change the position of a window on the screen.
window - Move this window
dx, dy - Move it that many pixels along the axis (right, down)
The window will move when the next input event will be received.

struct Gadget * gadget,
struct Window * window,
struct Requester * requester,
ULONG flags,
ULONG horizPot,
ULONG vertPot,
ULONG horizBody,
ULONG vertBody,
LONG numGad );
Changes the values in the PropInfo-structure of a proportional
gadget and refreshes the specified number of gadgets beginning
at the proportional gadget. If numGad is 0 (zero), then no
refreshing is done.
gadget - Must be a PROPGADGET.
window - The window which contains the gadget
requester - If the gadget has GTYP_REQGADGET set, this must be
flags - New flags
horizPot - New value for the HorizPot field of the PropInfo
vertPot - New value for the VertPot field of the PropInfo
horizBody - New value for the HorizBody field of the PropInfo

numGad - How many gadgets to refresh. 0 means none (not even
the current gadget) and -1 means all of them.
If NewModifyProp does not work for you, check if you
really have a gadget with GTYP_PROPGADGET set. If you
create a new gadget object from PROPGCLASS, you
might very well get a GTYP_CUSTOMGADGET gadget.
As a workaround, you might have to set the
gadget type to GTYP_PROPGADGET manually during the
call to NewModifyProp. Intuition does this, too.

Use this function to iterate through a list of BOOPSI objects.
You may do whatever you want with the object returned, even
remove it from the list or dispose it, and then continue to
iterate through the list.
objectPtrPtr - the pointer to a variable. This must be the same
variable, as long as you iterate though the same list. This
variable must initially be filled with the lh_Head of a list.
A BOOPSI object, which can be manipulated.

NULL if you don't have a pointer to a public screen.
namebuff - Pointer to a buffer with (at least) MAXPUBSCREENNAME+1
characters to put the name of the next public screen in.
Returns 'namebuff' or NULL if there are no public screens.
We cannot guarantee that the public screen, the name of which you got
by using this function, is available when you call for instance
LockPubScreen(). Therefore you must be prepared to handle failure of
that kind of functions.
This function may return the name of a public screen which is in
private mode.
The cycle order is undefined, so draw no conclusions based on it!

WA_PointerDelay (BOOL)
Set this to TRUE to delay change of the pointer image.
This avoids flickering of the mouse pointer when it's
changed for short times.
WA_HelpGroup (ULONG)
Get IDCMP_GADGETHELP messages not only from the active
window, but from all its windows.
You have to get a help ID with utility.library/GetUniqueID()
and use it as data for WA_HelpGroup for all windows.

a pointer to a Requester; otherwise the value is
numGad - How many gadgets should be refreshed. The value
may range from 0 to MAXLONG. If there are less gadgets
in the list than numGad, only the gadgets in the
list will be refreshed.
// Refresh one gadget
RefreshGList (&gadget, win, NULL, 1);
// Refresh all gadgets in the window
RefreshGList (win->FirstGadget, win, NULL, -1L);
This function *must not* be called inside a

Enable or disable the window flag REPORTMOUSE. If the flag is
set, you will receive an IDCMP event every time the user moves
the mouse.
flag - Enable (TRUE) or disable (FALSE) the reports.
window - Do it in this window.
As you might have noticed, the arguments are twisted.
BOOL Request(
struct Requester * requester,
struct Window * window );
Add a requester to specified window and display it.
requester - The requester to be displayed
window - The window to which the requester belongs
TRUE if requester was opened successfully, FALSE else.
EndRequest() InitRequester()
BOOL ResetMenuStrip(
struct Window * window,
struct Menu * menu );
Works like a "fast" SetMenuStrip() as it doesn't check Menu or
calculate internal values before attaching the Menu to the Window.
Use this function only if the Menu has been added before by
SetMenuStrip() and you changed nothing in the struct except
CHECKED and ITEMENABLED flags.
window - The window to add the MenuStrip to
menu - The menu to be added to the window above.
Always TRUE.
Yes, I do repeat it again:
Use this function only if the Menu has been added before by
SetMenuStrip() and you changed nothing in the struct except
CHECKED and ITEMENABLED flags.
LONG RethinkDisplay();
Check and update, i.e. redisplay the whole Intuition display.
RemakeDisplay() MakeScreen() graphics.library/MakeVPort() graphics.library/MrgCop() graphics.library/LoadView()
void ScreenDepth(
struct Screen * screen,
ULONG flags,
APTR reserved );
Move the specified screen to the front or back, based on passed flag.
If the screen is in a group, the screen will change its position in
the group only. If the screen is the parent of a group, the whole
group will be moved.
screen - Move this screen.
flags - SDEPTH_TOFRONT or SDEPTH_TOBACK for bringing the screen to
front or back.
If the screen is a child of another screen you may specify
SDEPTH_INFAMILY to move the screen within the family. If
not specified the whole family will move.
reserved - For future use. MUST be NULL by now.
Only the owner of the screen should use SDEPTH_INFAMILY.
Intentionally commodities should not change the internal arrangement
of screen families.
I am not sure, if it is enough to just send a SNOTIFY message to one
screen. I would suggest, the former FirstScreen gets a SDEPTH_TOBACK
message and the new FirstScreen gets a SDEPTH_TOFRONT message.
Currently only the screen supplied with ScreenDepth gets a message.
But those messages need to be sent in front of the actual
screen depth change because of the SNOTIFY_WAIT_REPLY-flag must be
able to block the action. But we only know after int_screendepth(),
if there was a change and which change took place.
So I leave it, as it is. This way SNOTIFY_WAIT_REPLY should work
at least. Is there something written in the AutoDocs, how this has
to be done (each screen gets a message)?
ScreenToBack() ScreenToFront()
void ScreenPosition(
struct Screen * screen,
ULONG flags,
LONG x1,
LONG y1,
LONG x2,
LONG y2 );
Move a screen to the specified position or by the specified
increment. Resolution is always the screen resolution.
If this move would be out of bounds, the move is clipped at
these boundaries. The real new position can be obtained from
LeftEdge and TopEdge of the screen's structure.
screen - Move this screen
flags - One of SPOS_RELATIVE, SPOS_ABSOLUTE or SPOS_MAKEVISIBLE
Use SPOS_FORCEDRAG to override non-movable screens ie. screens
opened with {SA_Draggable,FLASE} attribute.
SPOS_RELATIVE (or NULL) moves the screen by a delta of x1,y1.
SPOS_ABSOLUTE moves the screen to the specified position x1,y1.
SPOS_MAKEVISIBLE moves an oversized scrolling screen to make
the rectangle (x1,y1),(x2,y2) visible
x1,y1 - Absolute (SPOS_ABSOLUTE) or relative (SPOS_RELATIVE) coordinate
to move screen, or upper-left corner of rectangle
x2,y2 - Ignored with SPOS_ABSOLUTE and SPOS_RELATIVE.
Lower-right corner of rectangle with SPOS_MAKEVISIBLE.
SPOS_FORCEDRAG should only be used by the owner of the screen.
MoveScreen() RethinkDisplay()
void ScreenToBack(
struct Screen * screen );
Move a screen behind all other screens. If the screen is in a
group, the screen will be moved behind all other screens in the
group only. If the screen is the parent of a group, the whole
group will be moved in the back.
screen - Move this screen.
You will see the screen move behind all other screens. If some
screen before this screen occupies the whole display, then it
will disappear completely. If all other screens occupy only part
of the display, the screen will appear behind the screens.
ScreenToFront() ScreenDepth()
void ScreenToFront(
struct Screen * screen );
Move a screen in front of all other screens. If the screen is in a
group, the screen will be moved in front of all other screens in the
group only. If the screen is the parent of a group, the whole
group will be moved in the front.
You will see the screen move in front of all other screens.

WORD dx,
WORD dy,
WORD xmin,
WORD ymin,
WORD xmax,
WORD ymax );
Scrolls the content of the rectangle defined by (xmin,ymin)-
(xmax,ymax) by (dx,dy) towards (0,0). This function calls
The advantage of this function over calling ScrollRasterBF() is
that the window will be informed about damages. A damage happens
if in a simple window parts from concelealed areas are scrolled
to visible areas. The visible areas will be blank as simple
windows store no data for concealed areas.
The blank parts that appear due to the scroll will be filled
with EraseRect() and are not considered damaged areas.
win - pointer to window in which to scroll
dx,dy - scroll by (dx,dy) towards (0,0)
xmin,ymin - upper left corner of the rectangle that will be
affected by the scroll

BOOL SetDMRequest(
struct Window * window,
struct Requester * dmrequest );
Try to set the DMRequest of a window. A DMRequest is a requester that
appears if the user double-clicks with the menu button.
The new DMRequest will only be set if the old DMRequest is not in use.
The official way to change the DMRequest is to call ClearDMRequest()
until it returns TRUE and then call SetDMRequest().
window - The window from which the DMRequest is to be set
dmrequest - Pointer to the requester
TRUE if old DMRequest was not in use and therefore changed to
the new one, or FALSE if the old DMRequest was in use and could
not be set to the new one.
If the DMRequest has the POINTREL flag set, the DMR will show up
as close to the pointer as possible. The RelLeft/Top fields are
used to fine-tune the positioning.

struct Screen * screen,
BOOL ShowIt );
Modify SHOWTITLE flag of the screen and refresh the screen and
its windows.
If ShowIt is TRUE the screen's title bar will be shown in front of
WFLG_BACKDROP windows. A value of FALSE will bring the title bar
behind all windows.
The default of the SHOWTITLE flag for new screens is TRUE.
BOOL ShowWindow(
struct Window * window,
struct Window * other );
Make a window visible. This function does not bring the
window back into the visible area of the screen but rather
switches it into visible state.
Success indicator. On AROS it's always TRUE.

LONG SysReqHandler(
struct Window * window,
ULONG * IDCMPFlagsPtr,
BOOL WaitInput );
Handles a requester, which was opened with BuildSysRequest() or
BuildEasyRequestArgs(). When this function is called all outstanding
IDCMP requests are processed. If an IDCMP request that would close
a normal EasyRequestArgs() is encountered, SysReqHandler() returns
with a return code equally to the return code EasyRequestArgs()
would have returned. You may call this function in synchronous or
asynchronous mode, by setting the WaitInput parameter.
window - The window pointer returned by either BuildSysRequest() or
IDCMPFlagsPtr - Pointer to a ULONG to store the IDCMP flag that was
received by the window. This will be set if you
provided additional IDCMP flags to BuildSysRequest() or
BuildEasyRequest(). You may set this to NULL. You must
initialize the pointed to ULONG every time you call
WaitInput - Set this to TRUE, if you want this function to wait for
the next IDCMP request, if there is none at the moment
the function is called.
-2, if the requester was not satisfied. Normally you want to call
this function at least until this function returns something
different than -2.
-1, if one of the IDCMP flags of idcmpPTR was set.
0, if the rightmost button was clicked or an error occured.
n, if the n-th button from the left was clicked.

TMI Products Custom Seat Upholstery - How To Install Custom Seat Upholstery - Project Reclaim
TMI Products Now Offers Custom Seat Upholstery For Vintage Mustangs
In the early 1980s, we were grateful for reproduction seat upholstery kits of any kind for our '65-'73 Mustangs. As time passed, more and more colors and styles became available from the Mustang aftermarket. Over time, quality has only improved along with fit and finish. Few aftermarket companies have tried any harder to get it right and offer more options than TMI Products.
When Ron Bramlett and Bill Faull of Mustangs Plus contacted TMI's Dean Satterfield about seat upholstery for our Project Reclaim, they had a definite vision. They wanted it as distinctive as Reclaim is. And they wanted the comfort and good looks of TMI's Sports Seat. So they opted for the familiar '65-'66 Interior Décor Group ("Pony" interior) pattern without the galloping horses.
Dean came up with the pattern, made from simulated leather in medium gray with a blue carbon-fiber inset with the Project Reclaim logo stitched in the vinyl seatback. Then he enlisted the expertise of TMI's Esteben Orodonez and Carlos Aguilar to get the job done. Did you know TMI can do this for you as well? All you have to do is visit your favorite TMI Products dealer, including Mustangs Plus, and tell them what you'd like. Then let TMI Products make your dreams happen.

All things are against me.
Those were the words of Jacob, a patriarch of Israel (Genesis 42:36) and considering what he had been through in life, as well as what he now faced in old age, his moving lament was understandable.
Jacob's son, Joseph, had disappeared years earlier and this grieving father was convinced that he had died, probably having been killed by a wild animal.
Another son, Simeon, was being held hostage in Egypt, where he had gone with his brothers to get food enough to sustain their families through the famine that was devastating their homeland. Enduring the famine was stressful enough but now some Egyptian official was demanding Jacob send his youngest son, Benjamin, along on the next trip for food to secure Simeon's release.
What else could go wrong?
Perhaps that's how you feel today.
All the things you feared might someday come your way are arriving and you don't know what to do about it. You can identify with Jacob's pessimistic conclusion because it sounds like the story of your life, but it's important to know that this distressed father was wrong. All things weren't against him. Actually, the opposite was true.
Granted, Jacob had come through some tough times and his future appeared pretty bleak, but there were a number of unknowns working in his favor. Both of his sons were alive and well. Though Joseph had spent some time in prison, he had been released and now held one of the top positions in Egypt.
Jacob would see both of his sons again and Joseph would provide for him during the final years of his life. He would meet grandchildren he didn't know existed and pronounce blessings on them and their posterity. Things were going to turn out better than Jacob imagined when he concluded all things were against him.
During my teens, I discovered a Bible verse that I saw as a means of staying calm in any crisis, a faith builder for all circumstances: And we know that all things work together for good to those who love God, to those who are the called according to His purpose (Romans 8:28).
You've chosen a difficult Bible verse to live by, said my pastor; and I couldn't imagine what he could be talking about. Why would it be difficult to live by a promise that God is in control and would make everything work out for my good? Years later, after living through times that tested my faith, I would understand the wisdom of my pastor's words, but I have never found God's promises to be untrue.
A pastor once visited a farmer and saw a sign on his weathervane that said "God is love." Do you mean that God's love is as changeable as the weather? asked the pastor. No, replied the farmer, I mean God loves me no matter which way the wind blows.

Renesas Electronics Corporation today announced the availability of three new super-junction metal-oxide-semiconductor field-effect-transistors (Super Junction MOSFETs). This ultra-low on-state resistance and low gate charge combination benchmark, combined with the fast body diode feature, allow the new RJL60S5DPP, RJL60S5DPK and RJL60S5DPE devices to contribute to improved power efficiency in home appliance motor drives. Previously, home appliances used IGBTs with discrete Fast Recovery Diodes to enable a short reverse recovery time. Now, the need for higher switching speeds and lower loss is generating demand for Super Junction MOSFETs with fast recovery body diode characteristics. The Super Junction MOSFETs enable a decrease of the on-resistance without reducing voltage tolerance making it possible to produce MOSFETs with a lower on-resistance per unit of area. Renesas has developed a family of new high-performance Super Junction MOSFETs with high-speed body diodes, for low loss and improved high-speed switching performance.

What a pleasure it is to turn on my 40-inch LG LED TV at 12.30pm on a wet Thursday afternoon in November and hear that familiar Channel Nine cricket theme.
The cello's anticipatory halting strokes. The horns signalling the beginning of something monumental. The perfectly timed pieces of commentary. That abrupt crescendo. It's permanent. It's original. It's optimistic. And I want it played at my funeral.
Unfortunately this has been a sticking point with my partner ever since we had the "funeral" conversation eight years ago. I've toyed with other ideas. After the birth of my daughter in 2010, I went through a stage of thinking the final movement of Mahler's 3rd Symphony would be a tear-jerking reminder to the congregation how much they'll miss me. But now I think it may be too indulgent to force people to sit through 23 minutes of classical music at a funeral. I know they'd love the ending if they hung in there, but my gut feeling is I'd lose them during the quiet woodwind bits. Besides, it might be tricky finding enough sober images of me to fill the visual void for 23 minutes.
So I've come back around on the Channel Nine Cricket theme. I'm not sure about the commentary bits at a funeral. Probably inappropriate. Hopefully Channel Nine have a clean mix of it somewhere. In fact, I must sort that before it's too late. I don't want to cause undue hassle upon my expiration.
Apologies, I didn't mean this to be about death. I was meant to be celebrating the joys of the Southern Hemisphere television summer.
There are so many things about Channel Nine's cricket coverage that excite me. From the clean, clear graphics to the superb photography - every sun-soaked session is carefully covered by people who genuinely love the game. They spend hours honing their product.
Every aspect of the telecast is considered.
I once heard an interview with commentary legend Richie Benaud and while I can't remember who conducted the interview, I can recall him saying that it was Channel Nine's policy to introduce a new piece of televisual technology every summer. Sometimes the new arrivals are pointless, like the Gatorade Heart Tracker that reports heart rates 30 seconds after the fact, but most of the time they add value to the broadcast, like the introduction of Hotspot seven years ago or Snicko in the late 90s.
Occasionally the tweaks seem cosmetic (like the commentary menage-a-trois that was introduced a few years back) but they go on to become standard practice across the world.
But the real genius of the Channel Nine cricket coverage is the selection consistency of the commentary team - the core of which began their relationships with Kerry Packer, the former boss of Nine, when World Series Cricket was created in the late 70s. Bill Lawry, Tony Greig, Ian Chappell and Richie Benaud are to cricket what Peter Jennings or Walter Kronkite are to news.
They have watched years of cricket as players, captains and now commentators and are in no small way responsible for maintaining the dominant place that cricket culture holds in Australian life. They commentated my childhood backyard bowling practices. They added authenticity and weight to New Zealand's beautiful victories on Australian soil in 1985, '87 and 2011.
And this summer they'll again provide the vocal soundtrack to my life for four months, like a 100mg dose of Tramol, guiding me warmly through about 2700 overs of pure cricket viewing pleasure.
It's funny the things that make us live.

Jan. 31, 2009
HAMDEN, Conn. - She had a game-tying goal wiped out earlier in the game due to a crease violation. So perhaps it was only fitting that freshman forward Aleca Hughes got another chance at a big goal Saturday afternoon against Quinnipiac at the TD Banknorth Sports Center. And when Hughes got that chance, she delivered. Her tally with only 3.3 seconds on the clock in regulation lifted Yale to a thrilling 2-1 win over the Bobcats.
"Aleca just kept plugging forward [after having her first goal disallowed] ," said Yale head coach Hilary Witt. "She has a lot of composure, which is a good attribute to have. She came back to the bench and just said `Let's get another one.'"
Hughes slid the puck past Quinnipiac goaltender Nanna Holm-Glaas after taking a pass from senior forward Crysti Howser in the neutral zone.
"Howser worked the puck up, which is something we had struggled to do," said Witt. "When we don't do that, we become one-dimensional. It was a nice play by Howser, and nice to see Aleca get a goal. She works hard every day."
That made it a two-point day for Howser, who also assisted on senior defenseman Helen Resor's game-tying goal in the second period. Freshman Genny Ladiges stopped 16 of 17 shots to earn the win in net.
Quinnipiac (3-21-4, 2-10-4 ECAC Hockey) had an early flurry, and senior defenseman Carry Resor saved a sure goal by backhanding a rebound out of the crease just before a Bobcat player could get to it 2:30 in. The Bulldogs generated a scoring chance at the other end when forechecking from sophomore forward Lili Rudis created a turnover in the Quinnipiac zone, but junior forward Berit Johnson just missed putting home Rudis' crossing pass.
After Yale (9-13-0, 5-10-0 ECAC Hockey) came up empty on a power play midway through the first, the Bobcats went ahead on a goal by forward Chelsea Illchuk at 11:05. Yale finished the period with a 10-6 edge in shots on goal, but trailed 1-0.
The Bulldogs went scoreless on their first two power plays of the second period, though right after the second one ended they nearly scored the game-tying goal. Hughes picked up a loose puck after a blocked Yale shot and knocked it past Holm-Glaas at the 15:05 mark, but the goal was waved off as a Yale player had drifted into the crease.
Twenty-six seconds later, another Bobcat penalty allowed the Bulldogs to knot the game at one. Howser worked the puck up top to Resor, whose wrister through traffic beat Holm-Glaas high on her glove side at 15:31.
"We did a good job getting a lot of traffic in front on that play, and Helen made a great shot," Witt said.
The Bulldogs had to kill off a penalty of their own late in the period, but Ladiges came up with a pair of big saves followed by a clear by sophomore defenseman Samantha MacLean.
A high-sticking call on Quinnipiac with 1:14 left in the second period gave Yale a power play that wrapped around to the third period. Holm-Glaas made a big kick save on a shot from in front by Resor to help bring that power play to an end.
A hitting from behind and game misconduct call on Quinnipiac two minutes into the third would have given Yale a golden chance to take the lead, but a pair of Yale penalties that followed left the teams skating 4-on-4 for much of that five-minute period -- and at one point even forced Yale to kill off a brief 4-on-3. The Bobcats were hit with another penalty before the first one expired, but the Bulldogs could not convert during the 5-on-3.
Yale just missed taking the lead with nine minutes remaining when Holm-Glaas stopped a shot from the slot by senior forward Sarah Tittman.
After getting back into the lineup Friday night for the first time since an injury a month earlier, Tittman helped give the Bulldogs the chance to roll four complete lines for the first time in several weeks Saturday afternoon. The team captain centered a line with a pair of freshmen, Lauren Davis and Becky Mantell.
"We've got to get people involved and give people opportunities, since we need people to step up," Witt said. "Lauren, Becky and Tittman did a lot of really good things today. Tittman has had to fight very hard to get back on the ice. She's a senior and one of our leaders, and she knows this is her last chance. We were able to put her out there in all kinds of situations."
The Bulldogs had another opportunity to break on top with six minutes to play, but sophomore forward Bray Ketchum's blast hit the cross bar and ricocheted all the way out into the stands.
A pair of matching penalties with 2:31 to play led to four-on-four hockey, but neither team could take advantage. Yale outshot Quinnipiac 13-6 in the third, but the game was not settled until Hughes' dramatic goal.
The Bulldogs and Bobcats had entered the day tied for ninth in the ECAC Hockey standings, so the win gives Yale sole possession of ninth. The top eight teams make the playoffs, and the Bulldogs are six points behind both Cornell and Rensselaer for the final playoff spot. Yale has seven games remaining, while Cornell and Rensselaer have six.
Yale plays at Harvard next Friday at 7:00 p.m.
