Hello all,

I am using a composite widget (widget of custom widgets) with a
context menu.
Each of my child widgets has a context menu as well.

I would like in my composite to EXTEND all the context menus of child
widgets.

For the composite, I tried to reimplement
contextMenuEvent method (after setting
setContextMenupolicy(Qt.NoContextMenu) for each of my child widget).

How can I get the context menu of the childwidget in my
contextEventMenu?


    def contextMenuEvent(self, event):
        ''' The context menu created each time it is clicked! '''
        mousePositionAtEvent = event.pos()
        clickedWidget = self.childAt(mousePositionAtEvent)
        if clickedWidget :
            print "objectName %s" % (clickedWidget.objectName())
            print "class %s" % clickedWidget.__class__.__name__
            if getattr(clickedWidget,'createStandardContextMenu',None)
:
                menu = clickedWidget.createStandardContextMenu()
            else:
                menu = LContextMenu(self.dataContainer, self)
        menu.exec_(event.globalPos())


To my surprise the clickedWidget class/objectName changes function of
the child widget setContextMenuPolicy....
if ContextMenuPolicy is set to default, the composite contextMenuEvent
method of the composite is bypassed.
If setContextmenuPolicy is set to Qt.NoiContextMenu, the clickedWidget
doesn't have the createStandardContextMenu (!?) and class is QWidget
(!?!?) and object name is 'qt_scrollarea_viewport' (?!?)

My question:
How from my composite widget can I access the child widget context
menu. (Assume those child widgets have a method
createStandardContextMenu which returns their context menu!)

Please help...
