Hi, I have an application which will make a menu popup when you click button 1 which contains commands to do stuff...but I want it to disappear when button 1 is released. The effect I want is that while holding down the B1 you can drag your mouse down the list of commands and let go over one of them to initiate it and if you let go anywhere else (i.e. not over a menu command) the menu disappears. I bind B1-ButtonRelease to do an unpost() on the menu which is fine but while holding the button down the commands under the mouse wont activate...any ideas? Here's my code: 

#!/usr/bin/env perl
use Tk;
our $mw = MainWindow->new();
$mw->geometry('750x500');


$mw->Label(-text => 'Label 1')->pack();
$mw->Label(-text => 'Label 2')->pack();
$mw->Label(-text => 'Label 3')->pack();




$menu = $mw->Menu(-tearoff => 0);

$menu->add('separator');
$menu->add('command', -label => 'One', -command => \&item1);
$menu->add('command', -label => 'Two', -command => \&item2);
$mw->bind('<3>',                \&WorkspaceRightClick,        Ev('X'), Ev('Y'), Ev('W'));
$mw->bind('<B3-ButtonRelease>', \&WorkspaceRightClickRelease, Ev('X'), Ev('Y'), Ev('W'));

sub WorkspaceRightClick {
  my ($self, $x, $y, $widget) = @_;
  my $label = $widget->cget('-text');
  print "LABEL OF WIDGET UNDER ME IS $label\n";

  $menu->insert(1, 'command',
		-label => $label,
		-command => sub { print "Clicked $label.\n" },
	       );

  $menu->post($x, $y);
  $menu->delete(0,0);
}
sub WorkspaceRightClickRelease {
  my ($self, $x, $y, $widget) = @_;
  $menu->unpost();
}
sub item1 { print "Item 1!\n" }
sub item2 { print "Item 2!\n" }

MainLoop;
NOTE : if you comment out the ButtonRelease binding you can see the commands work .. but not while holding down the mouse..

In reply to tk menu commands dont work while button pressed by mpage
