QGraphicsProxyWidget undo ItemStacksBehindParent?

Goffer

Hello,
I'm running into a problem with items / widgets stacking.

I've:
QGraphicsItem
QGraphicsProxyWidget (parented under the QGraphicsItem)
QTextEdit in the QGraphicsProxyWidget

By default the QGraphicsProxyWidget has the ItemStacksBehindParent flag so that I cannot see nor interact with the QTextEdit, when double clicking on my QGraphicsItem, I remove the ItemStacksBehindParent flag so that my QTextEdits becomes visible and editable.

I can see it and it has focus but I cannot type anything in it...

If I remove the ItemStacksBehindParent flag , I can edit the QTextEdit properly but then I lose my QGraphicsItem behavior... and I need that behavior.

Any idea why the QTextEdit doesn't work with the flag? I'm sure I'm forgetting something stupid.

class GraphicsItem(QGraphicsItem):
    def __init__(self):
        super(GraphicsItem, self).__init__()

        self.browser = TextBrowser()
        self.editor = TextEdit()
        self.proxy = QtWidgets.QGraphicsProxyWidget(self)
        self.proxy.setWidget(self.browser)
        self.proxy.setFlag(QtWidgets.QGraphicsItem.ItemStacksBehindParent)
        self.displayedWidget = self.browser

    def mouseDoubleClickEvent(self, event):
        self.proxy.setFlags(self.flags() & ~self.ItemStacksBehindParent)
        self._swapWidget()
        super(GraphicsItem, self).mouseDoubleClickEvent(event)

    def _swapWidget(self):
        if isinstance(self.displayedWidget, QtWidgets.QTextBrowser):
            self.proxy.setWidget(self.editor)
            self.displayedWidget = self.editor
            self.editor.setFocus()

        else:
            self.proxy.setWidget(self.browser)
            self.displayedWidget = self.browser
            self.browser.setFocus()
            self.proxy.setFlag(QtWidgets.QGraphicsItem.ItemStacksBehindParent)

Thanks!
