8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	47 * A JFace window is an object that has no visual representation (no widgets)
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	48 * until it is told to open.
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	49 * <p>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	50 * Creating a window involves the following steps:
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	51 * <ul>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	52 * <li>creating an instance of a concrete subclass of <code>Window</code>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	53 * </li>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	54 * <li>creating the window's shell and widget tree by calling
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	55 * <code>create</code> (optional)</li>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	56 * <li>assigning the window to a window manager using
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	57 * <code>WindowManager.add</code> (optional)</li>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	58 * <li>opening the window by calling <code>open</code></li>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	59 * </ul>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	60 * Opening the window will create its shell and widget tree if they have not
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	61 * already been created. When the window is closed, the shell and widget tree
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	62 * are disposed of and are no longer referenced, and the window is automatically
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	63 * removed from its window manager. A window may be reopened.
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	64 * </p>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	65 * <p>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	66 * The JFace window framework (this package) consists of this class,
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	67 * <code>Window</code>, the abstract base of all windows, and one concrete
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	68 * window classes (<code>ApplicationWindow</code>) which may also be
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	69 * subclassed. Clients may define additional window subclasses as required.
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	70 * </p>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	71 * <p>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	72 * The <code>Window</code> class provides methods that subclasses may
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	73 * override to configure the window, including:
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	74 * <ul>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	75 * <li><code>close</code>- extend to free other DWT resources</li>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	76 * <li><code>configureShell</code>- extend or reimplement to set shell
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	77 * properties before window opens</li>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	78 * <li><code>createContents</code>- extend or reimplement to create controls
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	79 * before window opens</li>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	80 * <li><code>getInitialSize</code>- reimplement to give the initial size for
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	81 * the shell</li>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	82 * <li><code>getInitialLocation</code>- reimplement to give the initial
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	83 * location for the shell</li>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	84 * <li><code>getShellListener</code>- extend or reimplement to receive shell
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	85 * events</li>
8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	86 * <li><code>handleFontChange</code>- reimplement to respond to font changes

8a302fdb4140 Jface some window and resource classes Frank Benoit <benoit@tionex.de> parents: diff changeset	88 * <li><code>handleShellCloseEvent</code>- extend or reimplement to handle
