Binding mouse clicks in perl/Tk

blackadder has asked for the wisdom of the Perl Monks concerning the following question:

Greetings All,
I am trying to bind the mouse click actions to 2 separate sub-routines, eg: one click will bind to sub_one and double click will bind to sub_two, below is the script (I am new to Tk and was helped by monk .dave. to produce this script), please brethrens enlighten me.
And the Other thing is, the $output_text window appears to me that it will only display text, is it possible to include iconic display as well as text?

use Tk;
use strict;
use Tk::Text;
use Tk::Frame;
use Tk::DirTree;
use Tk::Adjuster;
use Tk::Scrollbar;
my $mw = new MainWindow;
$mw->geometry('500x600');
my $left_frame = $mw->Frame;
my $right_frame = $mw->Frame;
my $dir_label = $mw->Label(-text => 'Path :');
my $dir_name = $mw->Entry(-width => 30, -textvariable => \ my $variabl
+e);
my $adjuster = $mw->Adjuster(-widget=>$left_frame, -side=>'left'); 
my $list_box = $left_frame->Scrolled('DirTree', -height=>'0', -width=>
+'0',
-scrollbars =>'e',);
my $output_text = $right_frame->Scrolled('Text', -height=>'1', -width=
+>'1',
-scrollbars=>'osoe',);
$top_frame->pack(qw/-side top/);
####Errors occure in  this '#' enclosed section#######################
$list_box->bind('<ButtonRelease-1>', sub {my $indx = $list_box->cursel
+ection();
                    my $selected_object = $list_box->get($indx);});
$list_box->bind('<ButtonRelease-2>', sub{print “\nuser clicked twice”;
+});
#####################################################################
$dir_label->pack (qw/-side top -anchor w/);
$dir_name->pack (qw/-side top -anchor e/);
$left_frame->pack(qw/-side left -fill y/);        
$adjuster->pack(qw/-side left -fill y/);        
$right_frame->pack(qw/-side right -fill both -expand 1/);            
$list_box->pack(qw/-side left -fill both -expand 1/);        
$output_text->pack(qw/-side bottom -fill both -expand 1/);
MainLoop;
exit();

`ButtonRelease-1` binds to the event "Release of the first Button". `ButtonRelease-2` binds to the even "Release of the second button". What you want is `ButtonPress-1` and `Double-ButtonPress-1`. See also the Tk::bind manual page. As for your second question, yes, you can put images and other widgets in a Text widget. For details, see the Tk::Text manual page. Abigail	[reply] [d/l] [select]

You have bound probably not the exact thing you wanted. This binds button release for button one (left button) and two (middle button). Try `$list_box->bind('<Button-1>', sub { my $indx = $list_box->curselection(); my $selected_object = $list_box->get($indx); }); $list_box->bind('<Double-Button-1>', sub{ print “\nuser clicked twice”; });` [download] All of this good event binder information is in `perldoc Tk::bind`.
