Hello, I am converting an app. based on Athena widgets to Motif. One of the things it uses is the XmPanedWindow class. Once I create the widget I wish to keep the sash from appearing for the first child. How can I do this? A code fragment would be *greatly* appreciated. -Jim.

All you have to do is set the XmNpaneMaximum and XmNpaneMinimum PanedWindow constraint resources on the child to the same value. If you're explicitly setting the height of the child in question, then you can just set the resources to that value. See page 1-733, paragraph 3 of the 1.1 Programmer's Reference. For example: object push_button1 : XmPushButton { arguments { XmNheight = 100; XmNpaneMaximum = 100; XmNpaneMinimum = 100; }; }; If you don't explicitly set the height of the child, but rely on the parent's size and constraints to set the child's height, then it's a little more complicated. You'll have to manage the widgets first, query the XmNheight of the child and then set the panedMinimum and panedMaximum to that value. It may cause a brief flicker of the sash. I hope this helps. If you have any further questions, please let me know. W.

Then I saw your post and noticed that you referred to "XmNpaneMinimum" while all of my references refer to "XmNminimum". Has this been changed since 1.0? Here's a requested code fragment: { /* assume that widget has the child widget, and it's already been realized */ short height; /* notice that it's a short */ Arg argl[2]; XtSetArg(argl[0], XmNheight, &height); XtGetValues(widget, argl, 1); /* _not_ XmNminimum or XmNmaximum */ XtSetArg(argl[0], XmNpaneMinimum, height); XtSetArg(argl[1], XmNpaneMaximum, height); XtSetValues(widget, argl, 2); } -- Alan M.

I finally got the sash removal to work, but I still have a question. I'm running under SunOS 4.1.1, with Motif 1.1. What I needed was to have a Menubar in a paned window, without a sash. I did this by adding a callback to XmNmapCallback for the menubar, which when called sets the min and max size for the menubar to the current size. However, in order to get this to actually work, I also had to add an X event handler with a StructureNotifyMask, which if the event is a MapNotify, invokes XtCallCallbacks on the widget and XmNmapCallback. My question is, why did _I_ have to add this X event handler? Thanks! P.S. I know a lot of X window stuff, but very little Motif. -- Alan M.
