xow - A megawidget framework. This is a package that allows xotcl objects to be megawidgets.
Does this handle the option db correctly, do composition of megawidgets, handle focus and events right, etc.?
xcentuate - a theme engine for tk. This isn't all that important on windows, but on unix tk often needs a little help looking good. This package provides a very simple method of defining and changing the look of tk apps. It can even do it on the fly.
I would not propagate this in favor of Tile. There is also already the 'style' package in tklib (which again may be abortive when Tile becomes part of 8.5). What features does xcentuate really provide? Should they not just go into 'style'?
xout - a unit testing framework. I know, I know, tcl already provides one, tcltest. But I found tcltest to be too cumbersome and clunky. I'd write some tests, but maintaining those tests often was neglected because of the amount of programming overhead needed to write complex test cases. xout
Did you compare against tcltest v1 or v2?
I mention all of this because if other have some handy xotcl packages, I'd be interested in creating a formal xotcllib project. Perhaps something at sourceforge. I'll be making these available soon either way.
I think that would be a handy thing as an addon.
