XDefineCursor(3X11)     COMMAND REFERENCE     XDefineCursor(3X11)



NAME
     XDefineCursor, XUndefineCursor - define cursors

SYNOPSIS
     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 undoes the effect of a previous
     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.
