title: Problems with mousepressevent
body: <p>I just asked a similar question but (sorry!) I think I'll need more help. I have a problem with signals in pyqt. Let me post the whole code, it isn't long and it is easier for me to explain...</p>
  
  <pre><code>from PyQt4 import QtGui, QtCore, Qt
  import time
  import math
  
  class FenixGui(QtGui.QWidget):
  
      def backgroundmousepressevent(self, event):
          print "test 1"
          self.offset = event.pos()
  
  
      def backgroundmousemoveevent(self, event):
          print "test 2"
          x=event.globalX()
          y=event.globalY()
          x_w = self.offset.x()
          y_w = self.offset.y()
          self.move(x-x_w, y-y_w)
  
  
      def __init__(self):
          super(FenixGui, self).__init__()
  
          # setting layout type
          hboxlayout = QtGui.QHBoxLayout(self)
          self.setLayout(hboxlayout)
  
          # hiding title bar
          self.setWindowFlags(QtCore.Qt.FramelessWindowHint)
  
          # setting window size and position
          self.setGeometry(200, 200, 862, 560)
          self.setAttribute(Qt.Qt.WA_TranslucentBackground)
          self.setAutoFillBackground(False)
  
          # creating background window label
          backgroundpixmap = QtGui.QPixmap("fenixbackground.png")
          self.background = QtGui.QLabel(self)
          self.background.setPixmap(backgroundpixmap)
          self.background.setGeometry(0, 0, 862, 560)
  
          # making window draggable by the window label
          self.connect(self.background,QtCore.SIGNAL("mousePressEvent()"),         self.backgroundmousepressevent)
          self.connect(self.background,QtCore.SIGNAL("mouseMoveEvent()"), self.backgroundmousemoveevent)
  
  
          # fenix logo
          logopixmap = QtGui.QPixmap("fenixlogo.png")
          self.logo = QtGui.QLabel(self)
          self.logo.setPixmap(logopixmap)
          self.logo.setGeometry(100, 100, 400, 150)
  
  
  def main():
  
      app = QtGui.QApplication([])
      exm = FenixGui()
      exm.show()
      app.exec_()
  
  
  if __name__ == '__main__':
      main()
  </code></pre>
  
  <p>All right, so this is the code, it's just a simple gui that I wanted to make draggable around the screen clicking and dragging on any place in the background. My problem is: backgroundmousepressevent and backgroundmousemoveevent DON'T get fired when i press or move the button. So I wonder: where's the error? Did I mispell something or what? Thank you very much!</p>
