Synchronizing "Show XXX window" action checked state with some window's visibility

[abey]

Hello,

In my soft, I've got a windows and a menu item and related action to control the window's visibility. The action is checkable, so I can do

connect(action, SIGNAL(toggled(bool)), window, SLOT(setVisible(bool)));

connect(action, SIGNAL(toggled(bool)), window, SLOT(setVisible(bool)));

To copy to clipboard, switch view to plain text mode 

Is there an easy way to do the opposite -- ie. have the toggled state of the action updated whenever the visibility of the window changes?

TIA,
Antoine
