窗口的标识设置样例。

1. 得到 icon 的图片

    /* load the given bitmap data and create an X pixmap contianing it. */icon_pixmap = XCreateBitmapFromData(display,win,icon_bitmap_bits,icon_bitmap_width,icon_bitmap_height);if (!icon_pixmap) {fprintf(stderr, "XCreateBitmapFromData - error creating pixmap\n");exit(1);}

2. 初始化 标识 内存

    /* allocate a WM hints structure. */win_hints = XAllocWMHints();if (!win_hints) {fprintf(stderr, "XAllocWMHints - out of memory\n");exit(1);}/* initialize the structure appropriatly. *//* first, specify which size hints we want to fill in.  *//* in our case - setting the icon's pixmap, setting the *//* state hint as well as the icon position hint.        */win_hints->flags = IconPixmapHint | StateHint | IconPositionHint;/* next, specify the desired ihnts data.           *//* in our case - supply the icon's desired pixmap. *//* make the window's initial state be iconized,    *//* and set the icon position to the top-left part  *//* of the screen.                                  */win_hints->icon_pixmap = icon_pixmap;win_hints->initial_state = IconicState;win_hints->icon_x = 0;win_hints->icon_y = 0;

3. 在窗口中设置窗口标识

    /* pass the hints to the window manager. */XSetWMHints(display, win, win_hints);

4. 将标识的内存释放

    /* finally, we can free the WM hints structure. */XFree(win_hints);
