IntroductionQTcl is a Tcl extension module that provides a Tcl interface to the Qt widget set. This means that you can create Qt applications written in Tcl. When the QTcl module is loaded into a Tcl environment such as Geocap, it adds several commands to the set of built-in Tcl commands. These commands are all geared towards creating a graphical user-interface (GUI) to your application. This documentation gives an introduction to how QTcl works and contains a substantial amount of example scripts, almost all of which are complete programs that can be executed as-is. The reader is encouraged to use and modify these example scripts according to his own needs. The reader should be familiar with the basics of Tcl programming. A good way to start reading this documentation is by skimming through the different QTcl Widgets. This gives an immediate visual presentation of what QTcl is about. |
