XDefineCursor, XUndefineCursor - define cursors


SYNTAX

       XDefineCursor(display, w, cursor)
             Display *display;
             Window w;
             Cursor cursor;

       XUndefineCursor(display, w)
             Display *display;
             Window w;


ARGUMENTS

       cursor    Specifies the cursor that is to be displayed or
                 None.

       display   Specifies the connection to the X server.

       w         Specifies the window.


DESCRIPTION

       If a cursor is set, it will be used when the pointer is in
       the window.  If the cursor is None, it is equivalent to
       XUndefineCursor.

       XDefineCursor can generate BadCursor and BadWindow errors.

       The XUndefineCursor function undoes the effect of a previ-
       ous XDefineCursor for this window.  When the pointer is in
       the window, the parent's cursor will now be used.  On the
       root window, the default cursor is restored.

       XUndefineCursor can generate a BadWindow error.


DIAGNOSTICS

       BadAlloc  The server failed to allocate the requested
                 resource or server memory.

       BadCursor A value for a Cursor argument does not name a
                 defined Cursor.

       BadWindow A value for a Window argument does not name a
                 defined Window.
