A cursor is a small bitmap usually used for denoting where the mouse pointer is, with a picture that might indicate the interpretation of a mouse click.
A single cursor object may be used in many windows (any subwindow type). Each window has an individual cursor setting; when the mouse pointer is focused into a window, the pointer picture is changed to match the setting of the current window.
The wx:cursor% object wx:hourglass-cursor is predefined.
Creates an empty object.
