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
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.
