NAME
XIDefineCursor, XIUndefineCursor - define device cursors. SYNOPSIS
#include <X11/extensions/XInput2.h> int XIDefineCursor( Display *display, int deviceid, Window win, Cursor cursor); int XIUndefineCursor( Display *display, int deviceid, Window win); cursor Specifies the cursor that is to be displayed or None. deviceid Specifies the device whose cursor is to change. display Specifies the connection to the X server. win Specifies the window. DESCRIPTION
If a cursor is set, it will be used when the device's pointer is in the window. If the cursor is None, it is equivalent to XIUndefineCursor. The deviceid must be a master pointer device or a BadDevice error is returned. XIDefineCursor can generate BadDevice, BadCursor and BadWindow. The XIUndefineCursor function undoes the effect of a previous XIDefineCursor for this window. When the pointer is in the window, the window's default cursor will now be used. If no default cursor is defined, the parent's cursor for this device will be used (if defined) or the parent's default cursor will be used. XIDefineCursor and XIUndefineCursor are identical to XDefineCursor and XUndefineCursor but specify the device explicitly. XIUndefineCursor can generate a BadDevice and a BadWindow error. DIAGNOSTICS
BadCursor A value for a cursor argument does not name a defined cursor. BadDevice An invalid device was specified. The device does not exist or is not a pointer device. BadWindow A value for a Window argument does not name a defined window. See also XDefineCursor, XUndefineCursor 03/09/2013 XIDEFINECURSOR(3)
