Hi All,

I am writing code Perl TK. I am want to popup a widget such as “entry” or “label” at the mouse location in a tree widget. I have been trying ideas similar to what I have seen done with popup menu. I have read your peace “Tk::Wm::Popup” on CPAN. <\P>

"...For this discussion, we'll use the simple term dialog to refer any widget that pops up and awaits user interaction, whether it be a Menu, a special purpose Toplevel, or any of the dialog-type widgets, including, but not limited to, ColorEditor, Dialog, DialogBox, ErrorDialog, FileSelect, FBox, getOpenFile and getSaveFile. ..."

I assume that I should be able to able to popup simple widgets. Here is my test code. 

use         Tk;
use         Tk::Entry;
use         Tk::Tree;
use         Tk::Notebook;

use     warnings;
use     strict;

my $mw = MainWindow->new();

my $nb = $mw->NoteBook( -font => 'Tahoma 8 bold',
              )->pack( -side => 'top',
                   -anchor => 'ne',
                   -expand => 1,
                   -fill => 'both',
                 );

my $tb = $nb->add( 'Tab 1',
           -label => 'Tab1',
         );

my $tree = $tb->Scrolled( 'Tree',
              -background => 'snow',
              -selectmode => 'extended',
              -selectbackground => '#E0FFCC',
              -selectforeground => 'red',
              -highlightthickness => 0,
              -relief => 'ridge',
              -borderwidth => 2,
              -scrollbars => 'osoe',
              -drawbranch => 'true',
              -indicator  => 'true',
              -selectborderwidth => -1,
              -selectmode => 'extended',
              #-browsecmd => \&my_command,
            )->pack(-side => 'top',
                -anchor => 'nw',
                -expand => 1,
                -fill => 'both',
                   );

# ##=================================
# ## popup menu works fine
# ##=================================
# my $mb = $tree->Menu;
# $tree->bind("<Button-3>" => sub { $mb->Popup( -popover => "cursor",
#                           -tearoff => 0,
#                           -popanchor => 'nw',
#                           -overanchor => 'ne'
#                         )
#                 }
#        );
# 
# my $mdel = $mb->cascade( -label => 'Delete',
#              -tearoff => 0,
#                );
# 
# $mdel->command( -label => "Delete",
#         -command => sub{ my @E = $tree->info( 'selection' );
#                  foreach my $e ( @E )
#                    {
#                      $tree->delete( 'entry', $e);
#                    }
#                    }
#           );

##=================================
## popup an entry that does NOT work
##=================================
my $w = $tree->Frame();
$w->label( -text => 'popup label' );

$tree->bind("<Button-3>" => sub{ $w->Popup( -popover => "cursor",
                        -popanchor => 'nw',
                        -overanchor => 'ne'
                       )
                }
       );
