Re: Insight's dependance on libgui?

Hi,

If you're looking for a fast Table widget there is always the treeTable
widget from Source-Navigator.  A while ago we where going to remove
it from SN (also looking at a pure Tcl implementation), but with 10,000s
of symbols perform was bad.  In the end I did a minor rewrite of some
of the treeTable, mainly the redraw code which was very broken and
required maintain lots of call backs in Tcl for resizing everything,
now it resizes itself automatically .  I've not had to touch it since
making the redraw changes (your milage may vary).

Originally written by Khamis Abuelkomboz because there was nothing
fast enought to handle SN's symbol lists at the time.  Redhat owns
the Copyright and has released it under the GPL.

The files are snavigator/hyper/tkTreeTable.[ch].

If it's usage isn't straight forward you may have to look at the SN
code and see how it's used there.

Ian.
