Reveal Hint does not work (QKeyEvent does not work)

[hight996]

Problem description

It seems that the "reveal hint" action does not work. I would like to understand why, as I wish to add more registrable actions connected to keyboard shortcuts i.e. when I press a keyboard letter like "H" it reveals an image. It already works on my keyboard, I just cannot seem to assign this to the controller.

This is the code in the "actions.py":

@registerAction("Reveal Hint", "review")
def revealHint():
    evt = QKeyEvent(QEvent.KeyPress, Qt.Key_G, Qt.NoModifier)
    QCoreApplication.postEvent(mw, evt)

I tried to create this one following the same pattern:

@registerAction("Reveal image", "review")
def revealImage():
    evt = QKeyEvent(QEvent.KeyPress, Qt.Key_H, Qt.NoModifier)
    QCoreApplication.postEvent(mw, evt)

When I click on the assigned button, it shows me that I clicked on the "review hint" button, but nothing happens.
