python pyqt4 contextMenu on multiple pushButtons -

i'm trying build off example i've came across here: right click contextmenu on qpushbutton

how work when i'm creating button dynamically? can't figure out way dynamically create method on_context_menu.

here code have far.

import sys pyqt4 import qtgui,qtcore import sip  class layouttest(qtgui.qwidget):     def __init__(self):         super(layouttest, self).__init__()         self.setgeometry(300, 300, 400, 200)         vmasterlayout = qtgui.qvboxlayout(self)         self.hbox = qtgui.qhboxlayout()          in range(1,4):             self.butval = 'buttonmenu_%s' %             self.button = qtgui.qpushbutton(self.butval)             self.button.clicked.connect(self.allcheckbutton)             self.button.setcontextmenupolicy(qtcore.qt.customcontextmenu)             self.connect(self.button, qtcore.signal('customcontextmenurequested(const qpoint&)'), self.on_context_menu)              # create context menu             self.popmenu = qtgui.qmenu(self)             action = qtgui.qactiongroup(self, exclusive=true)             listver = ['image_v001','image_v003','image_v012','image_v120','image_v140', 'image_v013']             i, vdir in enumerate(sorted(listver)):                 x = action.addaction(qtgui.qaction( vdir, self, checkable = true))                 x.triggered.connect(self.foo(x.text()))                  self.popmenu.addaction(x)                 self.popmenu.addseparator()              self.hbox.addwidget(self.button)          vmasterlayout.addlayout(self.hbox)      def on_context_menu(self, point):         # show context menu         self.popmenu.exec_(self.button.maptoglobal(point))       def foo(self, name):         def poo():             print 'image version is: %s' % name         return poo      def allcheckbutton(self):         point = qtgui.qcursor.pos()         print point  def run():     app = qtgui.qapplication(sys.argv)     ex = layouttest()     ex.show()     sys.exit(app.exec_())  if __name__ == "__main__":     run() 

i've rewrite code: python pyqt4 contextmenu on pushbutton.

first of all, need able identify different buttons if want create them dynamically, i've created own qpushbutton class - mypushbutton.

after i've moved on_context_menu in class.

and third important thing i've connected mainform class , mypushbutton class buttonxclickedsignal signal , gives mainform class information button clicked can handle button clicked signal in mainform , whatever want different buttons.

here code (run , try click buttons , right click on buttons):

import sys pyqt4 import qtgui, qtcore  class mypushbutton(qtgui.qpushbutton):     def __init__(self, popmenu,elementid, mainform):         super(mypushbutton, self).__init__()         self.__elementid = elementid         self.__mainform = mainform         self.__popmenu = popmenu          self.connect(self, qtcore.signal('customcontextmenurequested(const qpoint&)'), self.on_context_menu)            self.connect(self, qtcore.signal('clicked()'),  self,        qtcore.slot("triggeroutput()"))          def on_context_menu(self, point):         # show context menu         self.__popmenu.exec_(self.maptoglobal(point))       @qtcore.pyqtslot()     def triggeroutput(self):         self.__mainform.emit(qtcore.signal("buttonxclickedsignal(pyqt_pyobject)"), self.__elementid) # send signal mainform class   class mainform(qtgui.qwidget):     def __init__(self, parent=none):         super(mainform, self).__init__(parent)         self.setgeometry(300, 300, 400, 200)         vmasterlayout = qtgui.qvboxlayout(self)         self.hbox = qtgui.qhboxlayout()          # custom signal         self.connect(self, qtcore.signal("buttonxclickedsignal(pyqt_pyobject)"),         self.buttonxclicked)          in range(1,4):             # create context menu             popmenu = qtgui.qmenu(self)             popmenu.addaction(qtgui.qaction('button %s - test0'%(i), self))             popmenu.addaction(qtgui.qaction('button %s - test1'%(i), self))             popmenu.addseparator()             popmenu.addaction(qtgui.qaction('button %s - test2'%(i), self))              # create button             self.button = mypushbutton(popmenu, i, self)                self.button.settext("test button %s" %(i))                 self.button.resize(100, 30)              # set button context menu policy             self.button.setcontextmenupolicy(qtcore.qt.customcontextmenu)                      self.hbox.addwidget(self.button)          vmasterlayout.addlayout(self.hbox)      def buttonxclicked(self, buttonid):         if buttonid == 1:              #do , call method ..             print "button id ", buttonid, " clicked"         if buttonid == 2:              #do , call method ..             print "button id ", buttonid, " clicked"         if buttonid == 3:              #do , call method ..             print "button id ", buttonid, " clicked"  def main():     app = qtgui.qapplication(sys.argv)     form = mainform()     form.show()     app.exec_()  if __name__ == '__main__':     main()
