Hi Richard,
Thanks for your response. I've also implemented a solution to this now,
which works a bit differently. I'll also paste it below and then others
can decide what the canonical solution should be...
The basic plan is to make the "file cut, copy and paste" actions
insensitive when a textual widget is in focus, which also has the effect
of disabling their accelerators and hence unblocking the default ones.
It doesn't cause any trouble as it isn't possible to execute these
actions anyway without moving the focus away from the text widget again.
So I inherit these actions from the following class. (The
isActiveOnCurrent method is filled in by the derived classes to
determine whether these actions should otherwise be sensitive)
Regards,
Geoff
# Cut, copy and paste
class FocusDependentAction:
def connectFocus(self):
self.widget.get_toplevel().connect("set-focus", self.focusChanged)
def focusChanged(self, window, widget):
freeTextWidget = isinstance(widget, gtk.Entry) or
isinstance(widget, gtk.TextView)
if freeTextWidget:
self.widget.set_sensitive(False)
elif self.isActiveOnCurrent():
self.widget.set_sensitive(True)
