Class WindowManager

java.lang.Object
  |
  +--ts.ui.WindowManager

All Implemented Interfaces:

java.util.EventListener, java.awt.event.MouseListener, java.awt.event.MouseMotionListener

public final class WindowManager

extends java.lang.Object

implements java.awt.event.MouseListener, java.awt.event.MouseMotionListener

A window manager singelton, that can handle any number of Windows. This manager handles window move and resize only. A window resize is conducted iff the mouse cursor is over the resize hotspot. This hotspot is always placed in the lower right corner by the manager, for every window it handles. A window move is conducted iff the mouse is pressed in the window, and then dragged (except in the hotspot area, of course). Be sure to leave some space in the window for the window itself, i.e. don't fill the window with components that grab mouse events.

The Windows managed by this class, should use lightweight components, at least in the area of the hotspot. If not, the peer component (e.g. a Panel) could grab the mouse event.
