Purpose: collect information and pointers to what mega[widget]s are, how to write them, etc. ---- Occasionally these have been called ''meta-widgets'' rather than megawidgets. ---- A mega widget is NOT an attempt to create new, unique, widgets. Instead, it is an effort to combine existing widgets in ways that are commonly needed (or at the very least interesting to the person who is writing the megawidget). ---- See also [Composite fields megawidgets]. See [Adding User Data to Widgets the Megawidget Way]. Steve Uhler's 1996 Tcl workshop presentation slides on the search for the perfect megawidget can be found at http://www.best.com/%7Esau/mega/. 282. Chengye Mao mailto:chengye.geo@yahoo.com has a web page which discusses building combined widgets (aka mega widgets) in pure Tcl at http://www.geocities.com/%7Echengye/comb.html. ---- Here are some of the megawidget frameworks of which I ([LV]) am aware. Please add to the following list. * [tkBuilder] * [MegaWidget package] * [mkextensions] , which include an object mechanism and mkWidgets for megawidgets. * [MIT otcl megawidget system] * [mwidx] * [obTcl] * [Pool] * [scwoop] * [Snit] * [Richard Suchenwirth] has a megawidget framework he has developed. * [tablelist] What: tablelist Where: http://www.nemethi.de/ Description: This is a Multi-Column listbox designed for Tcl/Tk 8.x as well as a general utility module for other megawidgets like tablelist.
