I created a model in QGIS 3.6 with three inputs parameters (two vector layer and one vector field).  When I run the model, the inputs are not sorted in a correct way: the vector field is requested before the vector layer.   For this simple example, it doesn't matter, however for more complex models with severals inputs, I fear the user could feel not confortable.   Is it possible to choose the order of the inputs parameters ?   Here are two screenshot.  "Conduite" = pipe in french "regard" = manhole in french  I want the user to select firstly "regard" layer, then "ID_regard" field within "regard" layer.
Using QGIS 3 graphical modeler I created a model with a variety of input parameters (> 10). When starting the model, a nice user interface is generated. But the arrangement of the GUI elements is totally confused and apparently unpredictable during creating the model. It does neither seem to depend on the arrangement of input parameters in the graphical modeler nor on the chronological order in which the input parameters are added to the model.   Is there a way that let's me arrange the GUI elements in the order I desire?
Labels and nesting gather and align I have nested gather and align according to  \begin{gather}        \sum\limits_{i=1}^n i + \text{expression} = \dfrac{n(n-1)}{2} \label{l1}\\        \begin{align}             a+\text{expression}&amp;=b \\ %\label{l2} doesnt work             c&amp;=d+\text{expression} \\             e+\text{long expression}&amp;=f-\text{expression}        \end{align}  \end{gather}   to get an output looking like this:   The problem is that it is not possible to label all equations separately. The problem is identical to that discussed in , except  that in my problem the first line needs to be centered.  Thanks for any help.

Assign default keyboard language per-application Is it possible to assign default keyboard language for specific applications? I know that there is an option to always start an application with a default keyboard language but this is not what I want.

Technical term for associating a group with the actions of a few component.set not working for picklist field I have a number of lightning:inputField that i'm setting based on certain criteria, these all work except for picklist field types. The code below shows how i am setting the fields. The country field is the picklist and the 2 alerts have the correct value in them, however the value is not getting set on country. Is there a different method for setting picklist fields?  var address = res.getReturnValue(); var country = component.find('Country__c'); var pcodeFld = component.find('Postcode__c');  if(country != undefined){  alert(country);  alert(address.Country);  country.set('v.value', address.Country); } if(pcodeFld != undefined){  pcodeFld.set('v.value', address.Postcode); }   EDIT: I can set a default value whilst using $A.createComponents using .set("v.value", "United Kingdom");  it just seems that i can't set it after the component has rendered based on some user action.

I am trying to enable the Edit button in Shutter. I installed the application from Ubuntu Software and are using Ubuntu 18.04.  After taking a screenshot the Edit button is disabled. And when hovering the mouse pointer over the button the text "Goo::Canvas/libgoo-canvas-perl needs to be installed for this feature" is shown.    I have tried to install the package libgoocanvas2-perl and restarted the computer, but the edit button is still not enabled:  sudo apt install libgoocanvas2-perl   That is the only package I can find.

I have several line layers (route, pipes, cables) that share the same geometry and would like to edit them simultaneously.   Is there a way to easily snap the geometry of the pipes and cables layers to the route layer so that I can simply change the geometry of the route layer and don't have to repeat all changes on the other two layers as well?  To clarify, I plan a fibreglass route and have three layers. The first one describes the route that I have to take to pass all homes that have to be connected. The second one contains the pipes in which the cables lie and the third layer is the cable layer. So all features on those layers have to have the same geometry. Once I change the pathway of the route layer, I have to apply the same changes to the other two layers to ensure that they are still aligned with the route layer. I'm not sure whether I understand your comments correctly, but I use the basic editing tools in QGIS 3. We're building a feature for a website and trying to think of a hypernym for clients, partners and members so that the feature remains generic enough for re-use later on other websites.

"me and my friends" vs. "my friends and me" or "my friends and I" Boundary condition with spatial derivative is ignored by NDSolve divides, not divides and cardinalities In group theory it happens very often that you want to say: "The order of $H$ divides / does not divide the order of $G$." But the length of | is then always the same:  $ |H| | |G| $ produces |H|||G|  which is not ideal at all. (The negation \nmid has just this length too.) The length of "divides" should be longer than the "cardinality length". I could use   $ |H| \big| |G|$  but then there is no good way to say "does not divide" with the same length. Also, \big| is no solution when the expression has to be used in subscripts.   I thought it was just me, but I asked other group theorists, and nobody had a solution. I hope there is one.  I am seeking a division sign which is a little longer than the usual | , allows negation (with the same length) and proportionally correct use in subscripts (also under \sum etc.). It does not look professional if the "order sign" has the same length as the "divides" sign. (And what about combinations with absolute values, norms - although personally I don't use them as often as group orders.)
