wm title . {Color Picker}LES This code doesn't work for me until I replace collist [list \ ... ] with collist { ... } and replace colnamelist [list \ ... ] with colnamelist { ... }SO 2005-01-08: ... hmmm... This code is certainly broken, I have no recollection of posting this (OTOH, I may not remember what I did yesterday ...). This was not something I wrote, but may well have been something I had on hand during the 8.0 days ... I will search the archives..pcam 2009-03-25: This code was simply the victim of pagination. The list command required the multiline command indicator \ at the end of each line. I took the easier approach and replaced the list command with the list definition { ... } and that was all it required.
WJP 2006-04-11: Here's a stand-alone color-picker that I wrote in Tcl/Tk: http://billposer.org/Software/ColorExplorer.html
.D. McC 2009-Mar-25: Or you could try WISH Color Picker Plus. pcam 25/03/2009. Tried it but your code required more modifications and editing (not directly rippable from wiki). Shame.HaO 2010-06-17 BWidget has a color picker called SelectColor - BWidget::SelectColor
SeS
2010-06-19 Yes, HaO, and here you see it in action, a demonstration of the current state of tG², BWidget's has some nice widgets, wish I had seen the tab/notebook much earlier...
