I have encountered an Xlib programming problem that I am unable to resolve.
Namely, the code below compiles on a Sparcstation 1 (R3), a NeXT (R3), a Mac
IIx (A/UX & R4), a DG AViiON (R3), and a Sun 3/50 (R3), runs (as a client on
any of these machines) under the X servers on the NeXT, Mac, and Sun 3/50, but
generates an X protocol error on the others' X servers as well as on a PC X
server. The X protocol error I get is:
X Protocol error: BadMatch, invalid parameter attributes
Major opcode of failed request: 1 (X_CreateWindow)
Minor opcode of failed request: 1
Resource id in failed request: 0x8006c
Serial number of failed request: 82
Current serial number in output stream: 85
Here's (portions of) the code:
Display *wndw_disp;
int wndw_screen;
Visual *visual;
XSetWindowAttributes WinAttr;
unsigned long WinAttrMask = CWBackPixmap;
Window win;
Window wndw_hndl;
Pixmap pix;
.
.
.
if (!(wndw_disp = XOpenDisplay("")))
{
printf("Can't connect to X server %s\n", XDisplayName(""));
exit(-1);
}
wndw_screen = DefaultScreen(wndw_disp);
wndw_hndl = XCreateSimpleWindow(wndw_disp,
DefaultRootWindow(wndw_disp),
wndw_hint.x, wndw_hint.y, wndw_hint.width,
wndw_hint.height,
border_w, wndw_foregrnd, wndw_backgrnd);
XSetStandardProperties(wndw_disp, *wndw_hndl, test_str, cur_title_str,
None, argv, argc, &wndw_hint);
.
.
.
pix = XCreateBitmapFromData(wndw_disp, wndw_hndl,
RawBitmapData, NumBitsPerBitmapLine,
NumLinesInBitmap);
WinAttr.background_pixmap = pix;
win = XCreateWindow(wndw_disp, DefaultRootWindow(wndw_disp),
ulx, uly, width, height, 4, 1, InputOutput,
DefaultVisual(wndw_disp,wndw_screen), WinAttrMask,
&WinAttr);
I get a similar X protocol error message when I use XCreateSimpleWindow and
XSetBackgroundPixmap instead of XCreateWindow etc. Can some kind soul help?etaylor@wilkins.iaims.bcm.tmc.edu (Eric Taylor) (12/15/90)

One glaring error is that you are assuming 1 bit deep display. You specify depth 1 for your window depth. Use DefaultDepth(wndw_disp,wndw_screen) instead. Another error: You are using XCreateBitmapFromData. You should be using XCreatePixmapFromBitmapData. As a rule, bitmaps are not suitable as background pixmaps. (There are situations where you want them, but this is not one) -- Eric Taylor Baylor College of Medicine etaylor@wilkins.bcm.tmc.edu (713) 798-3776

XCreateBitmapFromData creates a bitmap, which always has a depth of 1. You're then using this bitmap as a window background pixmap without checking the depth in your visual. If the window has a depth other than 1, you will get a protocol error. You must make sure that window background pixmaps have the same depths as the windows. -- Ken Lee DEC Western Software Laboratory, Palo Alto, Calif. Internet: klee@wsl.dec.com uucp: uunet!decwrl!klee

Help!
I am trying to run Mathematica remotely on an IBM RT and have
the graphics sent to my machine. I know that my DISPLAY variable
is set properly because xclock and xterm will both appear on my display.
However, when I try to plot inside Mathematica I get an X protocol
error. Please e-mail your suggestions and I will post a summary.
