Hello,
I'm playing around with Gtk menus in Perl. I would like to end up with a
custom drop down menu containing complex widgets, not simply menu items.
For that purpose I would display a custom built window and make it behave
like a menu (e.g. grabbing keyboard/mouse during its lifetime). I am mostly
done with that but I can't figure out how to replace the default handler
for the *activate *signal.
I tried with conventional signal connecting and stopping propagation from
inside the handler (code simplified to make it more readable)
$this->menuItem->signal_connect(activate => sub {$this->togglePopup()});
> sub togglePopup
> {
> my $this = shift;
> $this->menuItem->signal_stop_emission_by_name('activate');
> return 1;
> }
>From what I understood connecting handler the usual way would make it be
called before the default handler, so stopping the emission from my handler
makes sense. However the default handler still gets called. Even returning
TRUE doesn't help. I tried with signal_connect_after with no luck.
Then I tried another approach and made a custom MenuItem widget which
overrides the *activate *signal handler
package CustomMenuItem;
> use Gtk3;
> use Glib::Object::Subclass
> Gtk3::MenuItem,
> signals =>
> {
> activate_item => \&on_activate
> }
> ;
However, the custom handler seems to be ignored and instead the default
handler is still called.
Thanks,
Tihomir Mitkov
