I've created a custom widget which is used in a QMenu. Which the menu is displayed the user clicks on the Block rectangle as seen in the image below. However when i change the way the Menu is assigned to the control, it stops working for some reason.
However for some reason the menu does not show when i use this snippet of code:
menu_colors = QtGui.QMenu('Colors')
menu_colors.addAction(colAction)
self.ui_color_filter.setMenu(menu_colors)
instead of this:
fileMenu = menubar.addMenu('&File')
fileMenu.addAction(colAction)
self.ui_color_filter = ColorBlock()
self.ui_color_filter.setMenu(fileMenu)
Below is the full working example. Just un-comment the code to create the issue I'm trying to resolve. You'll notice the menu no longer will appear when clicking on the big black rectangle in the main part of the UI.

painter.fillRect(0, 0, self.width(), self.height(), QtGui.QColor(0, 0, 0, 255))

lay_main.setAlignment(QtCore.Qt.AlignTop)
lay_main.addWidget(self.ui_color_filter)
widget_main = QtGui.QWidget()
widget_main.setLayout(lay_main)
self.setCentralWidget(widget_main)
self.setGeometry(300, 300, 250, 150)
self.setWindowTitle('Menubar')
self.show()
def clicked_color(self, color):
print('Clicked:', color.isValid(), color)
self.ui_color_filter.color = color
self.sender().parent().hide()
app = QtGui.QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())
