It seems that when I execute XChangeWindowAttributes(...) to change the background pixmap of a window, the effect only takes place after the window is remapped. Looking at the source, XChangeWindowAttributes calles _XProcessWindowAttributes which seems to put the new data into the server and not do anything. Well, how do I make the change take effect NOW (XFlush won't work) ???? Thanks in advance. RF.

The background is used for painting the window after exposure. Try XClearWindow() to force an exposure. -- Ken Lee DEC Western Software Laboratory, Palo Alto, Calif.

Or until an exposure is generated some other way. Two quotes from the Xlib document: [after XSetWindowBackground and XSetWindowBackgroundPixmap] XSetWindowBackground and XSetWindowBackgroundPixmap do not change the current contents of the window. [under XChangeWindowAttributes] Changing the background does not cause the window contents to be changed. To repaint the window and its background, use XClearWindow. der Mouse old: mcgill-vision!mouse new: mouse@larry.mcrcim.mcgill.edu
