GUI example using GTK.

An important feature of these functions is that the label used for a button is also attached to the widget as user_data. Also, all created windows are linked via a backbone.
In this way the state of all buttons in all windows is reachable everywhere, without the use of global variables.

The set of functions are called "sgtk" (s of super, simple or what you like). They are archived using cvs at:

SGTK functions.

Some simple examples are:

• one_but.c: The most simple program.
  
• more_buts.c: Several button types.
  

A big example using this set of functions is the weather satellite program. See:

SSI archive.

For binaries of this program and a description see: here.

Compile for Windows.
