XDefineCursor(3)                                              XDefineCursor(3)




NAME

       XDefineCursor, XUndefineCursor - define cursors


SYNTAX

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

       int XUndefineCursor(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  previous  XDe-
       fineCursor  for  this  window.   When the pointer is in the window, the
       parent's cursor will now be used.  On the root window, the default cur-
       sor 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.
