      <description>
         This cheat sheet shows you how to create a &quot;Hello World&quot; application
			that uses the Standard Widget Toolkit (SWT). The application will
			simply display an empty window to the user.<br/>
			<br/>
			If you need help at any step, click the (?) to the right. Let&apos;s get
			started!

      <description>
         If you&apos;re not already in the Java perspective, in the main menu
			select <b>Window</b> &gt; <b>Open Perspective</b> &gt; <b>Java</b>
			or click on the &quot;Click to Perform&quot; link below.

   <item title="Download SWT standalone" dialog="true" skip="false" href="/org.eclipse.platform.doc.isv/guide/swt.htm">
      <description>
         Open your Web browser to http://download.eclipse.org/eclipse/downloads/,
			select the latest release build, and find the <b>SWT Binary and Source</b>
			download.<br/>
			<br/>
			Save the file to your disk; you do not need to extract the archive.

   <item title="Import the SWT project" dialog="true" skip="false" href="/org.eclipse.platform.doc.user/tasks/tasks-importproject.htm">
      <description>
         Import the SWT project from the main menu via File &gt; Import...,
			and select <b>Existing Projects into Workspace</b>. Specify the
			<b>archive</b> file you downloaded and click <b>Finish</b>.<br/>
			<br/>
			This will create the org.eclipse.swt project which we will need

      <description>
         Now we need a project to store our own source code. In the main
			toolbar, click on the <b>New Java Project</b> button, or click on
			the link below. Enter <b>HelloWorldSWT</b> for the project name,
			then click <b>Finish</b>.

      <description>
         Since our project requires SWT, we need to specify this in the
			project properties. Right-click on the project and select
			<b>Properties</b>.<br/>
			<br/>
			In the <b>Java Build Path</b> page open the <b>Projects</b> tab,
			add the org.eclipse.swt project, then click <b>OK</b>.

   <item title="Create a class" dialog="true" skip="false" href="/org.eclipse.jdt.doc.user/gettingStarted/qs-9.htm">
      <description>
         The next step is to create a new class. In the main toolbar,
			click on the <b>New Java Class</b> button (or the link below).
			If not already specified, select <b>HelloWorldSWT/src</b> as the source folder. Enter <b>HelloWorldSWT</b> for the class name and select the checkbox to
			create the <b>main()</b> method, then click <b>Finish</b>.<br/>
			<br/>
			The Java editor will automatically open showing your new class.

      <description>
         In the Java editor, enter the following Java code in the
			<b>main()</b> method:<br/>
			<br/>
			Display display = new Display();<br/> 
			Shell shell = new Shell(display);<br/> 
			shell.setText(&quot;Hello world!&quot;);<br/> 
			shell.open();<br/> 
			while (!shell.isDisposed()) {<br/> 
			if (!display.readAndDispatch()) display.sleep();<br/> 
			}<br/> 
			display.dispose();<br/> 
			<br/>
			You will get <b>compile errors</b>. Right click in the Java editor
			and select Source &gt; Organize Imports, then <b>save</b> your

   <item title="Run your Java application" dialog="true" skip="false" href="/org.eclipse.jdt.doc.user/gettingStarted/qs-12.htm">
      <description>
         To <b>run</b> your application, right-click on your class in the
			Package Explorer and select <b>Run As</b> &gt; <b>Java
			Application</b>. A new empty window should appear with the
