in that case I won't really clicked on the button right? in that case I won't have the css 
QPushButton:clicked{...}
used, right ?

today I try to figure, without success, if it would be possible to add some custom sub-controle like
the `hover`, and to set the sub-control from the code. For example, if I could have:

MyTreeview:item:WasLastSelected{ color-background: red}

since in MyTreeView object I have an eventFilter linked to the button, I can detect when my mouse
move over the button. So, if when this event is triggered I could set WasLastSelected = true

it would solved my problem (it's a guess, but I guess, it's a good guess)

Regads,
