Re: [perl-win32-gui-users] Is it possible to work on toolbar controls with win32::GUI

Selva,

I have managed to throw together a quick script that can be used to find 
info on a toolbar of another application. To use it, run the script and 
click and hold the left mouse button on the 'Find Window' button. This 
will hide the window, then while still holding the mouse button down, 
move the mouse over the toolbar of the other application and release the 
mouse. The window of the script should reappear, and display the number 
of buttons in the toolbar in the text box. Unfortunately, if you try to 
get the text of the toolbar buttons, the script crashes. At least, that 
is what happens for me when I try it on an instance of Notepad2 
<http://www.flos-freeware.ch/notepad2.html>. Not sure exactly what 
causes this. It may work for you. Try un-commenting the block of code in 
the onMouseMove event to see what happens. Anyway, here is my script:

#!perl
use strict;
use warnings;

use Data::Dump qw(dump);
#use Win32::API;
use Win32::GUI qw();
use Win32::GUI::Constants qw(CW_USEDEFAULT HOLLOW_BRUSH WM_USER);
#use constant {TB_GETBUTTON => WM_USER+23};

my $MouseDown = 0;
my $FoundHandle;
my $penHilight = Win32::GUI::Pen->new(-width => 5, -color => 0x000000, 
-style => 0);
my $winMain = Win32::GUI::Window->new(
     -name => 'winMain',
     -text => 'Window Finder',
     -size => [320,240],
     -left => CW_USEDEFAULT,
     -maximizebox => 0,
     -resizable => 0,
);

$winMain->AddButton(
     -name => 'btnWinFind',
     -text => 'Find Window',
     -pos => [$winMain->ScaleWidth()/2-40,5],
     -size => [80,25],
     -onMouseDown => sub {
         my($self,$x,$y,$flags) = @_;
         $MouseDown = 1;
         $winMain->Hide();
         $self->SetCapture();
         return 1;
     },
     -onMouseUp => sub {
         my($self,$x,$y,$flags) = @_;
         $MouseDown = 0;
         if($FoundHandle){
             Win32::GUI::InvalidateRect($FoundHandle, 1);
             Win32::GUI::Update($FoundHandle);
             Win32::GUI::Redraw($FoundHandle, 1);
             $winMain->Show();
             $self->ReleaseCapture();
             if(Win32::GUI::GetClassName($FoundHandle) eq 
'ToolbarWindow32'){
                 my $count = Win32::GUI::Toolbar::ButtonCount($FoundHandle);
                 $winMain->txtInfo->Text("$count\r\n");
#                foreach(0..$count-1){
#                    my $tbbutton = "\0" x 20;
#                    Win32::GUI::SendMessage($FoundHandle, TB_GETBUTTON, 
$_, $tbbutton);
#                    dump $tbbutton;
#                    my @button = 
Win32::GUI::Toolbar::GetButton($FoundHandle, $_);
#                    my @size = 
Win32::GUI::Toolbar::GetButtonSize($FoundHandle);
#                    my $text = 
Win32::GUI::Toolbar::GetButtonText($FoundHandle, $_);
#                    $winMain->txtInfo->Append(join "\r\n", @size);
#                }
             }
         }
         return 1;
     },
     -onMouseMove => sub {
         my($self,$x,$y,$flags) = @_;
         if($MouseDown){
             my $found =

                     my $oldbrush = Win32::GUI::DC::SelectObject($dc,

Win32::GUI::DC::Rectangle($dc,0,0,$rect{right}-$rect{left},$rect{bottom}-$rect{top});

                     Win32::GUI::DC::SelectObject($dc, $oldbrush) if 
$oldbrush;
                     Win32::GUI::DC::ReleaseDC($found, $dc);
                 }
                 else {
                     warn "Can't get DC: $^E";
                 }
             }
         }
         return 1;
     },
);

$winMain->AddTextfield(
     -name => 'txtInfo',
     -size => [$winMain->ScaleWidth()-10,$winMain->ScaleHeight()-40],
     -pos => [5,35],
     -multiline => 1,
);

$winMain->Show();

Win32::GUI::Dialog();

__END__

I based this code off of some C/C++ code that was posted here 
<http://www.codeproject.com/kb/dialog/windowfinder.aspx>.

Hope this helps,

Kevin.
