We create a dialog shell with XtCreatePopupShell() and use the transientShellWidgetClass class. The child of this shell is an Athena form widget containing some buttons and a type in text widget. We pop it up with XtPopup() and use the XtGrabExclusive flag, since we want a response from the user before he/she may use anything else in the client's other windows. When the user provides the necessary feedback, the shell is popped down, ending the exclusive grab. All this works fine with R4 twm. We tried it with OpenWindows 1.0 and noticed that the window manager decorated the window with the "tearoff" menu "pushpin" doodad. Cute, but also not so cute, since if the pushpin is clicked, causing the OpenWindows window manager to make the window nonvisible, the exclusive grab remains in effect, so further mouse and keyboard events are not accepted and the client must be killed. We'd like our client to work with OpenWindows, on the offhand chance that a user with plenty of memory and cpu power desires to use it :-). I have no idea how to deal with this. I put in a dummy destroy callback and saw that the OpenWindows window manager wasn't destroying the popup when the pushpin was clicked. Looking for UnmapNotify events won't work because there are other ways to generate that event where I don't want to manually pop the window down to release the exclusive grab (such as covering the popup with another window via the window manager). In my opinion, a transient window popped up with the exclusive grab flag set shouldn't have a pushpin on it, anyway. So, I would call this a bug. Because I haven't looked too hard and long at the OpenWindows documentation, I'm willing to consider other opinions and suggestions.

If you're interested in running your application with an OPEN LOOK window manager, try FTPing the sources to the "olwm" window manager from expo. They're with XView in the contrib area. s'marks Stuart W. Marks ARPA: smarks@eng.sun.com Window Systems Group UUCP: sun!smarks Sun Microsystems, Inc.
