Model: ItemIsUserCheckable

[weepdoo]

Ok, I should be (a very bit?) stupid!

The fault was in my "delegate" where I do only something like this:

def editorEvent(self, event, proxyModel, option, proxyIndex):
        eventType = event.type()
        if eventType == QtCore.QEvent.MouseButtonDblClick:
            [...] # <- we do not care
            return True
        return False

def editorEvent(self, event, proxyModel, option, proxyIndex):
        eventType = event.type()
        if eventType == QtCore.QEvent.MouseButtonDblClick:
            [...] # <- we do not care
            return True
        return False

Should I do something "else" ?
