-Subject: [PATCH] Fix click event for constant buttons
-
-It looks like the new style of "connect" tries to use the clicked
-signal as defined inside the function, which does not trigger
-slotClicked(). This change explicitly use the clicked signal from
-the (grand)parent class and the expected chain of signal/slots
-triggering is restored.
