XDefineCursor(3X)                               XDefineCursor(3X)



NAME
     XDefineCursor,  XUndefineCursor  -   define   and   undefine
     pointers

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

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

DESCRIPTION
     The XDefineCursor function defines the pointer that is used
     when the pointer is in the window.  Setting the value of
     cursor to None is equivalent to calling the function XUnde-
     fineCursor.

     The XUndefineCursor function undoes the effect of a previous
     XDefineCursor for this window.  When the pointer is in the
     window, the parent's pointer is used. On the root window,
     the default cursor is restored.

   Arguments
     These functions accept the following arguments:

     cursor  Specifies the pointer that is to be displayed when
             it resides in the specified window.  You can pass
             None if no pointer is to be displayed.

     display Specifies the connection to the X server.

     w       Specifies the window ID.

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

     BadCursor
             A value for a Cursor argument does not name a de-
             fined pointer.

     BadWindow
             A value for a Window argument does not name a de-
             fined window.

     The XDefineCursor function can generate BadAlloc,
     BadCursor, and BadWindow errors.
