Changing icon in nested menus

I don't think this may be posssible but I had still want to try asking. In the attached screenshot, I have nested menus.

Is it possible to change the arrow keys icon as 'highlighted' by the red box?

I am trying to change the arrow key to a plus icon if there are no sub menu items found. The default arrow can be in use if there are sub menu items found.

enter image description here

Yes, you can change the color of right-arrow.

But there is a trick to change it.

The truth of indicator is "branch-closed png file"

You can see the png file at the almost bottom on the page in the link.

So, it can not be solved by the pure-programmic way.

You prepare the picture in advance by yourself.

and please following code in QMenu constructor.

self.setStyleSheet("QMenu::right-arrow{image:url(stylesheet-branch-closed-red.png);}")

Attention:

stylesheet-branch-closed-red.png is my renamed picture.

You can download the original picture from the above link page.

you right-click the png picture and save as name.

This code comes from your past question.

class QCustomMenu(QtGui.QMenu):
    """Customized QMenu."""

    def __init__(self, title, parent=None):
        super(QCustomMenu, self).__init__(title=str(title), parent=parent)
        self.setup_menu()
        self.setStyleSheet("QMenu::right-arrow{image:url(stylesheet-branch-closed-red.png);}")
    def setup_menu(self):
        self.setContextMenuPolicy(QtCore.Qt.DefaultContextMenu)        
    def contextMenuEvent(self, event):
        no_right_click = [QAddAction]
        if any([isinstance(self.actionAt(event.pos()), instance) for instance in no_right_click]):
            return
        pos = event.pos()

    def addAction(self, action):
        super(QCustomMenu, self).addAction(action)

As the result, it will become like this.

You will dislike the white part of the arrow.

No problem, you can delete them clearly with a free-paint soft, but I didn't do it because it was needless.
