Vertical line spacing and a Win98/WinXP issue

[John Whitney-5]

Question 1)

Anyone know how to get multiple lines in a Win32::GUI::Label to spread out
vertially, so there would be an extra 5 pixels between each line?  Yes, I
could create multiple labels, one for each line, and spread them out an
extra 5 pixels.  But a simple -linespacing => 5 would be nice.  Anything
like this in the Win32::GUI world?  Below is the label I have.

my $window_main_text_label = new Win32::GUI::Label
(
  $window_main ,
  -text       => "Line 1 \n Line 2 \n Line 3 \n Line 4 " ,
  -name       => 'window_settings_option_text_label' ,
  -font       => $font ,
  -pos        => [ 195 , 297 ] ,
  -size       => [ 280 , 100 ]
) ;


Question 2)

With Win32::GUI::RadioButton, and with Win32::GUI::CheckBox I can set and
change the -foreground => 0x000000 value just fine to 0x000000 and 0xff0000
on my Win98SE PC.  But on my XP PC the $window_main_cb -> Change
( -foreground => 0xff0000 ) and the initial setting of the -foreground =>
0xff0000 has no effect.  Just always black.  I can change -background colors
on both Win98SE and WinXP platforms fine, but not -foreground.  Any
thoughts?  My solution is to have the radio button or checkbox without any
text, and add a text label near it that I can change the -foreground
and -background, but this is a kludge I would like to avoid.

You could try the "style" common option parameter.
I think one of them is line-height.

-pushstyle
-pushstyle => NUMBER
Add the specified styles to the window's style mask. This option can be repeated multiple times, or values can be 'or'ed together.

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.

John,

Win32::VisualStyles has XS code that calls the underlying Windows
functions. You will either need to compile the module yourself, or you
should be able to install the module using the Perl Package Manager.

John,

It is odd that PPM could not find the module. I tried it on my computer and managed to find it OK. Note that the package would be called Win32-VisualStyles (:: replaced with -). The repository that I use is http://ppm4.activestate.com/MSWin32-x86/5.12/1200/packages.xml, though it would be slightly different for you as you are using a different version of Perl. Try going to the web page http://ppm4.activestate.com/ and browsing for the appropriate repository for your version of Perl. You could also try downloading the package from http://ppm4.activestate.com/MSWin32-x86/5.8/825/R/RO/ROBERTMAY/Win32-VisualStyles/Win32-VisualStyles-0.02.ppmx and installing it yourself using the command line PPM.

Kevin.

Kevin:

Thanks again for your response.

That was the first thing I tried, was to enter PPM and look for it.  But I could not find it under search win32, search visual, or search style.  I was listed lots of packages with win32 visual or style in their name, but I could not find Win32-VisualStyles.  Again I apologize for missing something.  Is it under another name, or just not there?

John Whitney
