Introduction

First of all, is a library for Graphical User Interfaces (GUI). It was designed for quick and dirty use, cause its NOT object oriented. Therefor, it's easy to learn. Even beginners with little experiences in programming are now able to write first applications with graphical user interfaces.

The main goals of are:

• Easy to learn and use.


• Language independend. Currently can be used with Basic, C, Fortran and Pascal.


• Platform independent. Written on one platform, the application should run on another platform through recompiling. Supported platforms are currently all Win32, Linux and Solaris.

is build on top of the AWT. The AWT (abstract windowing toolkit) is part of the freely distributed Java Developer Toolkit (JDK). The AWT is composed of a package of classes and it supports everything from creating buttons, menus, and dialog boxes to complete GUI applications. Notable, the AWT is platform indepented.

The functionality of the AWT is now brought to the (classic) programming languages via . So you do not need to learn JAVA. All you need is a running Java Runtime Environment (JRE) on your host. If you don't have one, please have first a look at the link section.

There are a lot of wrapper files to bring the core functions to your preferred compiler. The following tables gives an overview to the supported compiler and interpreter:

	Ada	Basic	C	Fortran	Pascal
Win32	Gnat	Yabasic Scriba	GCC(Cygwin) GCC(Mingw) LCC BCC MSVC	G77(Cygwin) G77(Mingw) Lahey Imagine1 F Power Station Digital VF	FPK Delphi
Linux (x86)	Gnat	Yabasic Scriba	GCC	G77 Imagine1 F	GPC FPK
Solaris (Sparc)	-	Yabasic	GCC	G77	-
Solaris (x86)	-	Yabasic	GCC	G77	-

Lets have a look at the graphical components that comes with . The following list provides an overview over all available components:

• frame
• menubar, menu, menuitem, popupmenu
• canvas
• button, graphicbutton
• label, graphiclabel
• checkbox
• radiobutton
• choice
• list
• textarea, textfield
• scrollbar
• panel
• scrollpane
• dialog
• window
• filedialog

To do the layout of your application you can either use fix coordinated to place the components in your main window, or you can use one of the layout manager that comes with (the preferred method for platform independent programing):

• flowlayout
• gridlayout
• borderlayout

Every component comes with its own action event. To react to aditional user actions, there are five listeners which can be bound to all of the components:

• mouselistener
• keylistener
• focuslistener
• componentlistener
• windowlistener

There are a lot of graphic commands available. The following list provides an overview to the graphic primitives:

• colors
• setforegroundcolor
• setbackgroundcolor
• graphic primitives
• draw pixel
• draw (poly) line
• draw (filled) polygon
• draw (filled) rectangle
• draw (filled) round rectangle
• draw (filled) circle
• draw (filled) oval
• draw (filled) arc
• image functions
• load image
• save image
• get (scaled) image
• draw (scaled) image
• get image source
• draw image source

Least, there are some goodies coming with like printing and some C-functions which are not available in some languages:

• debug window
• printing
• some C functions (sleep, random)
