NAME

Win32::GUI - Perl Win32 Graphical User Interface Extension

SYNOPSIS

use Win32::GUI();

Table of Contents

Due to the volume of Win32::GUI documentation it is split into a number of different sections. The documentation is sparse in some areas, and incomplete in others. Patches are welcome. The documentation does not try to be a tutorial for Windows GUI programming, although the tutorial should give enough information for a beginner to get started. For advanced features knowledge of the Win32 API is assumed, and further information can be found from Microsoft's online resources (http://msdn.microsoft.com/).

Sample Code

There is a set of sample applications installed with Win32::GUI, that should be found in the .../Win32/GUI/demos/ directory under your library installtion root (by default for ActiveState perl this is at C:/Perl/site/lib/Win32/GUI/demos). There is a viewer/launcher application installed as well. Type win32-gui-demos at a command prompt.

EXPORTS

Release of Win32::GUI up to and including v1.03 export a large list of constants into the callers namespace by default. This behaviour is changed in releases from v1.04 and onwards.

From v1.04 the support for constants is provided by Win32::GUI::Constants, and the prefered way of getting constants exported into your namespace should be:

use Win32::GUI();   # Empty export list to prevent default exports
use Win32::GUI::Constants qw( ... ) # explicitly list wanted constants

although, for backwards compatibility the following are also supported:

use Win32::GUI;

Will continue to export the same list of constants as earlier versions, but will generate a warning (under the use warnings; pragma or with the -w command line option to perl). In the future (v1.07 and later) this syntax will stop exporting anything. v1.07 will generate a warning that nothing is being exported. v1.08 will silently export nothing.

use Win32::GUI qw( ... );

Will exported the requested list of constants. The full syntax allowed by Win32::GUI::Constants may be used.

Please see the v1.04 Release Notes for further information on backwards compatability and making old scripts work.
