void
XSetSubwindowMode(display, gc, subwindow_mode);
Display *display = Dsp;
GC gc;
int subwindow_mode = IncludeInferiors;
>>SET need-gc-flush
>>ASSERTION Good A
A call to xname sets the
.M subwindow_mode
component of the specified GC to the value of the
.A subwindow_mode
argument.
>>STRATEGY
Create window.
Create child window fully obscuring the parent.
Create GC with subwindow_mode = IncludeInferiors, fg = WhitePixel, bg = BlackPixel.
Draw point (0, 0) on ParentWindow.
Verify pixel at (0, 0) is fg using XGetImage and XGetPixel.
Verify pixel at (0, 1) is bg using XGetImage and XGetPixel.
Set subwindow_mode of GC to ClipByChildren with XSetSubwindowMode.
Set pixel at (0, 1) on parent window.
Verify pixel at (0, 1) is bg using XGetImage and XGetPixel.
>>CODE
XVisualInfo *vp;
Window pwin, cwin;
XGCValues values;
resetvinf(VI_WIN);
nextvinf(&vp);
