Introduction:
-------------

     The GXL graphical interface library provides the C++ programmer
with software tools to create a powerful and flexible graphics
interface.  The library is built using an event driven architecture
which allows program actions to be queued and processed as events.
This approach allows an application to cooperatively share processor
time between user-input polling, printing, and for example, updating a
clock on the display.  It also has the added advantage of allowing
program functions to be initiated or handled generically.  This means
that your application doesn't need to concern itself with whether a
mouse button was clicked or a touch-screen was pressed, it just
responds to the event sent by an object selected on the screen.
     GXL is intended to serve as the foundation for a graphical
application by providing the neccessary services to manage events and
displayed objects.  In addition to ready-to-use objects, simple base
classes are provided from which customized objects can be created.

     Now in it's second version, GXL is a complete re-write of the
original "GL" which was designed as an interface library for
Point-Of-Sale applications.  GL was used to develop several kiosk products.  
Now, GXL is currently being used in public information kiosk applications 
by Hise Development.

Some of the ready-to-use objects you can build an application with:

- 3D 'chiseled-look' buttons and icons.
- Windows that can be re-positioned (click-and-drag on title bar).
- A desktop or canvas customizer.
- Text with different fonts and justifcation.
- Blinking text.
- Analog and digital clocks.
- Scroll bars and List boxes.
- Text input fields.

Some sample applications are also shown:

- A screen saver.
- A simple Point-Of-Sale interface.

System Requirements:

- An IBM or compatible computer.
- MS-DOS 3.x or later.
- At least 384kb of free RAM.
- A VGA display card and monitor.
- A Microsoft or compatible mouse (driver).

Note: You may also run the demo as a full-screen DOS application in
      OS/2 2.x or MS-Windows 3.x.
