in reply to perl Tk help

does perl Tk supports things like radio buttons,dropdown list,

Have you looked at the widget demo that comes with Tk? It contains radio button and dropdown list examples. Just type "widget" at a command prompt if you have Tk installed, or look in the Tk source/demos directory for the widget demo.

Other than Tk, I also like Gtk2 for GUI's.

Just in case you have a hard time wrangling the code out of the demo's, here are a couple of simple examples.


#!/usr/bin/perl use warnings; use strict; use Tk; my $mw = MainWindow->new; my $rb = 'first button'; my $rb1 = $mw->Radiobutton(-text => "Button One", -value => 'button1', -variable => \$rb)->pack; my $rb2 = $mw->Radiobutton(-text => "Button Two", -value => 'button2', -variable => \$rb)->pack; my $b1 = $mw->Button(-text => 'Show', -command => [ \&showRB, \$rb ])- +>pack; MainLoop; sub showRB { print "Arg list is @_ \n"; my $state_ref = shift; my $state = $$state_ref; print "$state\n"; $mw->messageBox(-title => 'Status', -type => 'OK', -message => "Status is :$state:."); }
and a drop down menu
#!/usr/bin/perl use warnings; use strict; use Tk; my $top = MainWindow->new; $top->geometry('200x200+100+100'); # Menubar my $menu = $top->Frame(-relief => 'raised', -bd => 2); my $menu_pulldown = $menu->Menubutton(-text => "Test", -underline => 0); $menu_pulldown->command(-label => "Exit", -command => sub { exit 0 }); # Cascade Menu $menu_pulldown->cascade(-label => "Cascade", -underline => 1,); my $newmenu = $menu_pulldown->cget(-menu)->Menu; $menu_pulldown->entryconfigure('last', -menu => $newmenu); $newmenu->command(-label => "CascadeCommand", -command => sub { exit 0 }); $menu->pack(-side => 'top', -fill => 'x'); $menu_pulldown->pack(-side, 'left'); MainLoop;

I'm not really a human, but I play one on earth.
