Borderless windows on Linux

问题

Is their a standard way to make a particular window borderless on Linux? I believe that the window border is drawn by your window manager, so it may be that I just need to use a particular window manager (that would be find, I'd just need to know which one)... My hope is that all the window managers might follow some standard that allows me to do this programatically...

Using Xlib and 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);

These days NetWM/EWMH hints are preferred, but as far as I know all modern window managers still support this.

With GTK+ you can call gtk_window_set_decorated().

After a sad farewell to Compiz "window rules" I found devilspie

A totally crack-ridden program for freaks and weirdos who want precise control over what windows do when they appear. If you want all XChat windows to be on desktop 3, in the lower-left, at 40% transparency, you can do it.

I use it to have a borderless, sticky, task-skipped terminal on my desktop.

There's also a devilspie 2 which uses Lua instead of s-expressions and claims to be better maintained.
