I was wondering if anybody could help me in trying to mask the menu bar.
If it is possible, I would like to display an image over the menu bar.
I've tried FillRect(&screenBits,black). This blacks out everything on the
screen except the strip of bar on the top of the screen where the menu bar
would be had I defined one. I'm using Lightspeed C, v.3.0. I've also try
simply drawing a window over it, but the menu bar refuses to go under.
I would greatly appreciate any help or suggestions. Thanks in advance.

In article <2832@skivs.UUCP> choi@skivs.UUCP (Al Choi) asks how to draw an image over the menu bar. I did the following to get a full-screen window, but note that it is very fragile: the menu bar still responds to mouse clicks, and desk accessories or inits such as superclock don't notice that you've covered the image. It works on both Mac SE's and color Mac II's. It has not been blessed by Apple. The actual drawing was done in response to the update event. show_window() { GrafPtr old_port; GetPort(&old_port); SelectWindow(screen_window); ObscureCursor(); ShowWindow(screen_window); /* * This is needed to get a full-screen window. * It effectively hides the menu bar. It must * be after ShowWindow(). */ CopyRgn(screen_window->clipRgn, screen_window->visRgn); SetPort(screen_window); InvalRect(&thePort->portRect); /* Trigger update event */ SetPort(old_port); } screen_window was defined as follows: SetRect( &window_bounds, 0, 0, screenBits.bounds.right - screenBits.bounds.left, screenBits.bounds.bottom - screenBits.bounds.top ); /* * Note that this window is the size of the entire screen, including * the menu bar. The call to CopyRgn in show_window() above * changes the clip region so the menu bar is covered. I have no * idea if this is strictly koscher. */ screen_window = NewWindow( NIL, /* Allocate storage */ &window_bounds, /* Screen size */ "\p", /* No title */ FALSE, /* Don't draw it yet */ plainDBox, /* Plain box */ BRING_TO_FRONT, /* Where on screen */ FALSE, /* No GoAway box */ 0 /* No refCon */ ); Hope this helps.

This should get rid of the menubar entirely, and allow you to use that part of the screen for a regular window. Just remember to fix the menubar before you switch out (in MultiFinder). --- Alexis Rosen temporarily at spector@vx2.gba.nyu.edu alexis@rascal.ics.utexas.edu (last resort)

There's no such trap. There is a low-memory global called MBarHeight. Like all system low-memory globals, you should avoid writing to it; Inside Mac v5 allows it to be written only by menu bar definition procedures, and only to be set to a value larger than the size of the system font. Despite the fact that it's so commonly done, overwriting the menu bar is a violation of the Mac user interface guidelines and should be avoided. -- Tim Maroney, Consultant, Eclectic Software, sun!hoptoad!tim "Now hear a plain fact: Swedenborg has not written one new truth: Now hear another: he has written all the old falshoods.
