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.

wSpecifies 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
