Hello, This is a question along the lines of: Open Look has a particular feature that I am using, and I would like to find an equivalent feature or method in Motif (or in Xt!). The Open Look feature that I am using is the _OL_WIN_BUSY_ property that a client may set on a window. When this property is set on a window, the Open Look window manager assumes that that window is busy, grays out the window header and traps all keyboard and mouse input to the window. The window will beep in response to any input. (This is detailed on p74, Open Look Intrinsics Toolkit Widget Set Programmers Guide, version printed 6/11/90.) Different ideas I have considered using in Motif are: setting XtNsensitive to FALSE on a parent widget inside a particular window, and/or not accepting Focus events. But, there doesn't seem to be any way to ask MWM or other WM's to change the appearance of the window header to appear inactive. Has anyone else considered this? Or devised/found some method for accomplishing this? thanks in advance, Tracy Wiseman * Unify Corporation * Sacramento, CA * (916)920-9092 * tracy@unify.com *

It sounds misleading, your last part -- it does not confine mouse movement to the window. It sounded as tho you implied that. It also changes the cursor to a timeout cursor. The fact that the cursor is specified causes consistency among all OL apps -- this is the part that Motif needs (a specific and consistent description of what should happen in such a state [popping up a "working dialog" is not sufficient]). > Different ideas I have considered using in Motif are: setting > XtNsensitive to FALSE on a parent widget inside a particular window, > and/or not accepting Focus events. What you can do is use XtGrabPointer()/XtGrabKeyboard() (both have masks to grab both the mouse and the keyboard) and you can specify a function to call in case of mouse or keyboard events. That function can call XBell(). The XtGrab* functions can also set the cursor to be whatever you want (might as well steal the OL cursor :-) and you have just about everything. > But, there doesn't seem to be any > way to ask MWM or other WM's to change the appearance of the window > header to appear inactive. That you're going to have to live without. dan ---------------------------------------------------- O'Reilly && Associates argv@sun.com / argv@ora.com Opinions expressed reflect those of the author only.
