- <title>SWT - Example Launcher</title>
-</head>
-<body>
-
-<h2>SWT Example Launcher</h2>
-
-<p>
-The Example Launcher is used to launch SWT examples which can either be Workbench Views,
-or Standalone applications.
-</p>
-
-<ul>
-<li>Workbench Views are examples that are integrated into Eclipse. When the Launcher
-starts a Workbench View, it is opened in the currently active perspective.
-<li>Standalone applications are launched in a separate window.
-</ul>
-
-<h3>Running the Example Launcher</h3>
-
-<p>
-From the Window menu, select Show View --> Other.
-In the Show View dialog, expand SWT Examples and select the SWT Example Launcher view.
-A view containing a list of examples will appear in your current perspective.
-Select an example from the list. A brief description of the example is displayed.
-Click on the Run button to launch the example.
-</p>
-
-
-<h3>Details</h3>
-<p>The example launcher view contains a tree list, a text area, and a button.
-The tree list contains a list of all the SWT examples you can choose
-to run. When an example is selected from the tree, the text area
-displays a short description of the example. The selected example can
-be launched by clicking on the Run button. Standalone examples are run in the
-same thread as the workbench's UI but they are not integrated into the perspective.
-The launcher invokes the <code>open()</code> method of the standalone example.
