I am writing a motif application which has many top-level windows. I would like to have the pointer change to a watch in all those windows to notify the user to wait. Unfotunately, it looks to me like you have to do a XDefineCursor using the window ID for EACH of the popup windows to get that to happen. Is there anyway around this? I tried using the toplevel widget returned from XtInitialize, but that only changes the pointer for that window. Thanks in advance, Eric Slimko

I chose to create an InputOnly window with its pointer defined as a stopwatch. By mapping the window, all user-generated input events can be safely ignored until the processing is completed upon which the window is unmapped. But I get the same behavior as Eric is having :-( I have even tried to force it to be the top window in the stacking order as well as setting the override_redirect window resource to True. Both attempts made no difference. Here is [the perintent portions of] my code: To initialize the shells and InputOnly window and cursor: ... [ the first top level shell created here ] ... XSetWindowAttributes attr; attr.override_redirect = True; Dimension x, y, width, height; argcnt = 0; XtSetArg(args[argcnt], XmNx, &x); argcnt++; XtSetArg(args[argcnt], XmNy, &y); argcnt++; XtSetArg(args[argcnt], XmNwidth, &width); argcnt++; XtSetArg(args[argcnt], XmNheight, &height); argcnt++; XtGetValues(Top_app_shell, args, argcnt); Wait_window = XCreateWindow(Main_display, Main_window, x, y, width, height, 0, 0, InputOnly, DefaultVisualOfScreen(Main_screen), CWOverrideRedirect, &attr); Wait_cursor = XCreateFontCursor(Main_display, XC_watch); XDefineCursor(Main_display, Wait_window, Wait_cursor); ... [ other top level application shells created here ] ... And when extended processing is about to occur: XMapRaised(Main_display, Wait_window); XmUpdateDisplay(Top_widget); And when processing is completed: XUnmapWindow(Main_display, Wait_window); It works fine when the mouse pointer is in the "Wait_window", but the pointer changes back when in other top level shells. Are the other shell windows overriding the XMapRaised call? I thought it might be mwm getting in the way, so I ran it with no wm but no difference.

Try mapping an InputOnly window on top of *all* of your toplevel windows. Give it a watch cursor. Do something like the following for all of your toplevel widgets after they are realized: typedef struct _BusyWindowRec { Window window; /* busy window */ Widget w; /* widget which needs the busy window */ } BusyWindowRec, *BusyWindow; void CreateBusyWindow(busy) BusyWindow busy; { unsigned long valueMask; XSetWindowAttributes attributes; /* *Ignore device events while the busy cursor is displayed. */ valueMask = CWDontPropagate | CWCursor; attributes.do_not_propagate_mask = (KeyPressMask | KeyReleaseMask | ButtonPressMask | ButtonReleaseMask | PointerMotionMask); attributes.cursor = appData.busy_cursor; /* * The window will be as big as the display screen, and clipped by * it's own parent window, so we never have to worry about resizing. * (well, almost never) */ busy->window = XCreateWindow(XtDisplay(busy->w), XtWindow(busy->w), 0, 0, WidthOfScreen(XtScreen(busy->w)), HeightOfScreen(XtScreen(busy->w)), (unsigned int) 0, CopyFromParent, InputOnly, CopyFromParent, valueMask, &attributes); } Andrew _______________________________________________________________________________ Andrew Wason Bell Communications Research aw@bae.bellcore.com Piscataway, NJ bellcore!bae!aw

I believe the only way to do this is to have a 'watch' window for each
shell in your application. The server clips the 'watch' window to its
parent _window_, not application. It knows diddly about your hierarchy,
which is maintained/organized/etc. on the client end. To show the watch,
map & raise all 'watch' windows.
Good luck, and let us know if you find a better way.

As far as I know, that's correct. So I ended up with writing a little
extra code which maintains a list of windows and when asked, change
the cursor of all those windows to either a watch or an arrow.

It's much much easier than that. You could simply create a large InputOnly window as a child of your top-level window, set the cursor to whatever you want and XMapRaised the thing. Simply unmap it to get rid of your cursor. I'm not an Xt user so I can't tell you if there are any problems with this approach. -- (I kid you not)Tom LaStrange toml@Solbourne.COM

Look in the FAQ under comp.windows.x. With very few lines of code, it is easy to create an input-only window the size of the entire screen. That window is a child of the toplevel shell's window, and is clipped to the size of its window. The input-only window is the size of the screen to handle any resizing of your toplevel shell. Now simply XDefineCursor() a suitable busy cursor for the input-only window. When your app is busy, map the window.
