bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	48 * A JFace window is an object that has no visual representation (no widgets)
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	49 * until it is told to open.

bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	51 * Creating a window involves the following steps:
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	52 * <ul>
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	53 * <li>creating an instance of a concrete subclass of <code>Window</code>
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	54 * </li>
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	55 * <li>creating the window's shell and widget tree by calling
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	56 * <code>create</code> (optional)</li>
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	57 * <li>assigning the window to a window manager using

bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	61 * Opening the window will create its shell and widget tree if they have not
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	62 * already been created. When the window is closed, the shell and widget tree

bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	64 * removed from its window manager. A window may be reopened.
