John,
Question 1:
After looking through the Windows SDK docs, as far as I can tell, labels
don't allow you to set the line spacing of the text. The best I can
think of is to either choose a font with a large line spacing, or you
could create an owner drawn control and draw the text yourself.
Question 2:
After doing a bit of digging, it seems that if you have themes enabled,
the method that Win32::GUI uses to change the background and foreground
colours doesn't work. Depending on the version of Perl that you use, the
themes may be enabled or not. For example, I use ActiveState Perl 5.12.0
which has themes enabled by default. Robert May released a module called
Win32::VisualStyles (it's on CPAN) which you can use to control the
styles applied to your window. Simply disable themes before creating the
checkbox and the foreground and background colors will be applied. Here
is an example:
#!perl
use strict;
use warnings;
use feature qw(:5.12);
use Win32::GUI qw();
use Win32::GUI::Constants qw(CW_USEDEFAULT);
use Win32::VisualStyles qw(:all);
# Enable themes only for window, disable for controls
SetThemeAppProperties(STAP_ALLOW_NONCLIENT);
my $win = Win32::GUI::Window->new(
-name => 'win',
-size => [ 320, 240 ],
-left => CW_USEDEFAULT,
);
$win->AddCheckbox(
-pos => [ 5, 5 ],
-text => 'Checkbox',
-foreground => 0x0000ff,
-background => 0x00ff00,
);
$win->Show();
Win32::GUI::Dialog();
__END__
As an alternative, you could draw the text in the control yourself using
an owner drawn checkbox.
Hope this helps,
Kevin.
