[perl-win32-gui-users] Graying out checkbox

[Christian Kappler]

Hello listers,

I would like to gray out a checkbox in some situations. The Win32::GUI
documentation says that, to do this, I should call the SetCheck([VALUE])
method with the value 2 to set the checkbox to indeterminate or gray. I
tried it on my NT-workstation, but the checkbox only becomes "checked", but
not grayed. Is there something I do wrong or some other way to set a
checkbox to indeterminate?

I send some demonstration code bellow.

Regards,

  Christian

*** Code follows ***

#!perl

use Win32::GUI;

$Win = new Win32::GUI::Window(
  -name => 'Win',
  -title => 'Testing Checkbox',
  -height => 300,
  -width => 400,
);

$Win->AddCheckbox(
  -name => 'CB',
  -top => 130,
  -left => 50,
  -height => 20,
  -width => 300,
  -text => 'This checkbox should be indeterminate (grayed)',
);

# Setting the checkbox state to 2 (grayed):
$Win->CB->SetCheck(2);

# Display the window with the checkbox:
$Win->Show();
Win32::GUI::Dialog();

sub Win_Terminate {
  return -1;
}
