[PATCH] Improve signal/slot connections for KActionCollection::add()

[Michael Pyne]

Hi all,

template<> KActionCollection::add(name, obj, slot) has a problem connecting 
the "triggered" signal of the created QAction to the given slot when the slot 
accepts a bool parameter.  I've attached a patch to improve our handling of 
this issue and allow slots with a bool parameter or no parameter.

i.e. right now this wouldn't work:

QAction *act = actionCollection->add<KToggleAction>("show", this, 
SLOT(setShown(bool)));

in spite of the fact that the triggered signal has a bool parameter because 
the connection is from triggered().

The patch fixes this by converting triggered() signals to triggered(bool) in 
the connection.  Existing code which connects to a slot with no parameters 
would be unaffected as Qt will simply ignore the extra parameter.

Any comments?

Regards,
 - Michael Pyne
