Package org.eclipse.jface.window
Class WindowManager
java.lang.Object
org.eclipse.jface.window.WindowManager
A manager for a group of windows. Window managers are an optional JFace
feature used in applications which create many different windows (dialogs,
wizards, etc.) in addition to a main window. A window manager can be used to
remember all the windows that an application has created (independent of
whether they are presently open or closed). There can be several window
managers, and they can be arranged into a tree. This kind of organization
makes it simple to close whole subgroupings of windows.
Creating a window manager is as simple as creating an instance of
WindowManager
. Associating a window with a window manager is
done with WindowManager.add(Window)
. A window is automatically
removed from its window manager as a side effect of closing the window.
