Hi,
I want to declare a signal handler as in
__gsignals__ = {
'foo': (GObject.SignalFlags.RUN_LAST, None,
(GObject.TYPE_POINTER,)),
}
I have a do_foo method but the parameter passed is actually a
GdkEventButton (or rather a Gdk.EventButton in Python) - the signal is
emitted in a 'button-press-event' signal handler.
My problem is the event object I have in the 'button-press-event'
signal handler and pass when emitting 'foo' is not a
GObject.TYPE_POINTER. I tried GObject.TYPE_OBJECT as well to no avail.
The error is: TypeError: could not convert type EventButton to
gpointer required for parameter 0
How do I declare a signal handler such that I can pass a
GdkEventButton instance as argument to the signal handler?
I had to do the same when porting an application from GTK2 to GTK3.
GTK2 version:
__gsignals__ = {
'clicked' : (gobject.SIGNAL_RUN_LAST, gobject.TYPE_NONE,
(gobject.TYPE_STRING, gtk.gdk.Event))
}
GTK3 version:
__gsignals__ = {
'clicked' : (GObject.SIGNAL_RUN_LAST, None, (str, object))
}
I was confused at the beginning because Gdk.Event didn't work anymore,
but passing it as a Python object seems to do the trick.

Thanks
