However it's possible to make it do so by selecting the SubstructureRedirectMask so that everytime the xterm resizes, you get a ConfigureRequest. That's originally how I used xterm as a widget. The original project I wrote that used the embedded xterm is no longer maintained. I do however have some more recent code that demonstrates the sequence with ntk in a prototype: http://code.google.com/p/megapkg/source/browse/trunk/tclsrc/xterm_proto.tcl Note: I decided I may need the ability to render offscreen with the XComposite, and XDamage extensions (at the least), so that it would work with NexTk and overlapped windows. I'm willing to write an xterm widget that embeds xterm as a Tk widget, but I don't always have a lot of time and/or motivation. I'll see if I can piece some code together this week though. The Whim desktop could use a Whimterm or something like that. George
