XSetWMHints()XSetWMHints()NameXSetWMHints – set a window manager hints property.
Synopsis
XSetWMHints(display, w, wmhints)
Display *display;
Window w;
XWMHints *wmhints;
Arguments
display Specifies a connection to an X server; returned from XOpenDis‐
play().
w Specifies the ID for which window manager hints are to be set.
wmhints Specifies a pointer to the window manager hints.
DescriptionXSetWMHints() sets the window manager hints that include icon informa‐
tion and location, the initial state of the window, and whether the
application relies on the window manager to get keyboard input.
This function is unnecessary in Release 4 and later if you call XSetWM‐
Properties().
See Volume One, Chapter 12, Interclient Communication, for a descrip‐
tion of each XWMHints structure member.
