Hello. I am using the Motif Paned Window (the widget where children are stacked vertically and separated by a control sash that the user can move up and down). I have two children. Although the top one in my REAL application is more complex, let's say they are both Scrolled Text windows (the top one is actually a scrolled window). When this monster comes up on the screen, the control sash is up at the top of the paned window, the top edit window is squished to invisibility, and the bottom window takes up all the space. How can I control where the sash goes? +--------------------------------------+ +----------------------------------[]--+ | | | bottom edit widget | | | +--------------------------------------+ My other problem is how do I move the sash and set maximum sizes on the fly? I've been setting constraint resources on the children of the paned window (i.e. my two scrolled text windows), but to no avail. Anybody with a couple of tips? -simon tooke -- =============================================================================== Simon Tooke SCO Canada, Inc.

When you find out, please let me know. Here are some tips. First of all, make sure you are setting the constraint resources on the parent of the widget returned from XmCreateScrolled..., since that's the scrolled window and the actual child of the paned widget. Secondly, I believe that those resources may only be checked at manage time, which would be wrong, but I might be wrong on that one. The one situation that I have managed to make work is if you want the first item to come up according to the constraints and the subsequent one to fill in the remaining space. However (according to the comments in my code) the only way I could make this work was to manage the paned window, let it return to the main loop, and then manage the children. I've thought of playing with misusing the insertChild callback to try and size the children, but I have a feeling that won't work. Any other ideas would be appreciated.
