使用Xlib和old
_MOTIF_WM_HINTS：
struct MwmHints { unsigned long flags; unsigned long functions; unsigned long decorations; long input_mode; unsigned long status;};enum { MWM_HINTS_FUNCTIONS = (1L << 0), MWM_HINTS_DECORATIONS = (1L << 1), MWM_FUNC_ALL = (1L << 0), MWM_FUNC_RESIZE = (1L << 1), MWM_FUNC_MOVE = (1L << 2), MWM_FUNC_MINIMIZE = (1L << 3), MWM_FUNC_MAXIMIZE = (1L << 4), MWM_FUNC_CLOSE = (1L << 5)};Atom mwmHintsProperty = XInternAtom(display, "_MOTIF_WM_HINTS", 0);struct MwmHints hints;hints.flags = MWM_HINTS_DECORATIONS;hints.decorations = 0;XChangeProperty(display, window, mwmHintsProperty, mwmHintsProperty, 32, PropModeReplace, (unsigned char *)&hints, 5);这些天NETWM / EWMH提示是首选，但据我所知，所有现代的窗口管理器还支持这一点。
