Here are 3 examples. 1 is a popup on a button, the others
on a label.
They might show a way to get it working on an Entry.
Hope they save you some searching thru the archives! :-)
0m,
zentara
On a button:
#!/usr/bin/perl
use warnings;
use strict;
use Gtk2 -init;
#by muppet
my %items = map {
my $foo = $_;
( $foo => sub { print "$foo\n"; } )
} qw(red orange yellow green blue indigo violet);
my $window = Gtk2::Window->new;
$window->signal_connect( destroy => \&Gtk2::main_quit );
my $menu = Gtk2::Menu->new;
my $submenu = Gtk2::Menu->new;
while ( my ( $label, $callback ) = each %items ) {
my $item = Gtk2::MenuItem->new($label);
$item->signal_connect( activate => $callback );
$item->show;
$submenu->append($item);
}
my $item = Gtk2::MenuItem->new("Foo");
$item->set_submenu($submenu);
$menu->append($item);
$item = Gtk2::MenuItem->new("Baz");
$item->signal_connect( activate => sub { print "Baz!\n" } );
$menu->append($item);
$menu->show_all;
my $button = Gtk2::Button->new("Clicky Clicky Clicky");
# only works when you click, not if you activate the button with the keyboard
$button->signal_connect(
button_press_event => sub {
my ( undef, $event ) = @_;
$menu->popup( undef, undef, undef, undef, $event->button,
$event->time );
1;
}
);
$window->add($button);
$window->show_all;
Gtk2->main;
__END__
and here is one on a Label. It appends to the conventional right click menu
#!/usr/bin/perl -w
use strict;
use Gtk2 -init;
# by muppet
my $window = Gtk2::Window->new;
my $label = Gtk2::Label->new ("Hi, i am a label");
# This is what will make it possible to get the context menu on the label
$label->set_selectable (1);
$label->signal_connect (populate_popup => sub {
my (undef, $menu) = @_;
my $item = Gtk2::MenuItem->new ('Whee');
$menu->append ($item);
$item->show;
});
$window->add ($label);
$window->signal_connect (destroy => sub { Gtk2->main_quit });
$window->show_all;
Gtk2->main;
__END__
and another on a Label, that overrides the default right click.
