Many toolkits for the creation of GUI's exist. In the Tcl world, Tk is one of the most commonly used, but there are Tcl bindings for other toolkits as well; see for instance Alternative GUI Toolkits .

Perhaps the commonest example that new Tcl programmers call to mind arises in dealing with long-running calculations. If the GUI is to be kept alive, then it must get some CPU resources, even if the long-running calculation doesn't relinquish them willingly.

Tcl/Tk: A Developer's Guide, authored by Clif Flynt is in its third edition (2012). It is now published by Elsevier .

With every other Tcl interpreter I've tried, up and down work like Ctrl+P and Ctrl+N (previous and next history command). With WindowsNT_kbsvq8.6-gui.exe, up and down move the cursor around the widget. APN: This has nothing to do with tclkit per se. Some changes in the Tk bindings made somewhere around the 8.6b3 time are the cause.

A Starkit is a single file packaging of Tcl scripts, platform specific compiled code and application data; designed to facilitate simple deployment of cross platform applications. The name comes from STandAlone Runtime.

A sample GUI editor written in Tcl is provided. A new version is almost finished with full MDI support (multi menu), Popup Menu, Growable and dockable dialog boxes, Tooltips. Licence is free of charge, doc is in the form of a Winhelp file, Source available on request.

Unfortunately, there is no direct way to specify a minimum slider size in Tcl (without writing a platform-specific extension module). However, you can fix this problem easily enough by once again modifying the commands linking the scrollbar and its associated window.

Now I can quickly make color-gradient 'button files' by doing screen/window captures of this GUI --- with a screenshot utility, like 'gnome-screenshot' on Linux. Below is the code for this 'gradient-button-maker' GUI. It includes plenty of comments to explain the GUI.

Does anyone know hot to enable/disable parts of a GUI being created in tk, based on user input on the same screen. What I mean is, I have all the frames created in a single window, and want to enable some frames as and when a user requires that option.

In 1995, shortly after the 3'd Tcl/Tk Workshop, held in Toronto, TclTutor was released on an unsuspecting populace. Since then, there have been over a million of downloads, 3 major rewrites of the GUI, a translation into Portuguese, a rework …
