Purpose: to collect tips, suggestions, questions, and examples where
developers have written tcl/tk code that ''wraps'' around an
existing GUI window.

In particular, I'm interested in hearing people talk about 
doing this under the X Window System.

Has anyone an example, for instance, of embedding perhaps an xterm
inside a tcl/tk frame?

Why?  Well, perhaps, for example, to have an application to which one could
easily add buttons for generating key sequences or command strings, etc.

otherwise make time for this, e-mail CL.  I
think I know what you're after.]]

Thanks.  A developer here is wanting to use something like this and then
to set transient wm hints via tk, to get certain behavior characteristics
to take place.

See BLT's 'container' command. From the man page...

''The container widget lets you embed an X11 window from a foreign application into your Tk application. The foreign window is reparented inside of the widget. You can then place and arrange the container just as you would any Tk widget.''

See the page about the TkXext extension at http://wiki.tcl.tk/2116  It's a compiled Tcl/Tk extension. I think it only works on X11 on Unix/Linux. But you can embed non-Tcl/Tk windows inside a Tk frame with it. I used it in a project on Slackware 7.2 Linux with Tcl/Tk 8.4 and it worked well.

[LV] Has anyone used the [frame] -container option to do this sort of thing?
