public abstract Class Cursor

Returns the 'best' cursor size based on the given preferred size.

Shows or hides the cursor.

If the cursor is currently hidden with a previous call to setVisible(false), setting a new cursor shape (e.g. by means of calling Window.setCursor()) does not automatically display the cursor on the screen until the client code calls setVisible(true) to show the cursor again.

If the mouse cursor is located over a non-Glass window at the time of calling this method, the call may or may not affect the native cursor's visibility. This behavior is platform-dependent.

When the mouse pointer is moved over a non-Glass window, depending on the native platform behavior, the cursor may or may not become visible on the screen, even if it was previously hidden by calling setVisible(false). After this occurs, on some platforms the cursor may even remain visible permanently. For example, Mac OS X makes the cursor visible unconditionally when the mouse is moved over the Dock or Menu Bar areas. There's no way to detect that the native cursor became visible, however, from Glass perspective it is still considered hidden, and thus, when the mouse cursor is needed again, the app should call setVisible(true) in order to continue to operate properly.

Calling this method multiple times with the same argument may not have any effect. For example, if the cursor was hidden and the native OS restored its visibility, calling setVisible(false) again may not hide the cursor. If the app needs to ultimately hide the cursor, it should first show the cursor again, and then proceed with hiding it.
