    <h2 class="tutorial"><a name="intro"></a>Introduction to Project Types</h2>
    
    <p>A <i>project type</i> is a NetBeans Platform term for a grouping of
         folders and files that is treated as a single unit. Treating
         related folders and files as a single unit makes working
         with them easier for the end user.One way in which a project
         type simplifies life for the user is that you are able to fill
         the Projects window only with those folders and files that the end user
         is most likely to work.</p> <p>For example, the Java
         project type in NetBeans IDE helps the end user to work with the folders
         and files belonging to a single Java application. As you can see
         below, the folders and files the end user most needs to work with
         are shown in the Projects window:</p>

    <p><img border="1" src="../../images/tutorials/projecttypes/sample-3.png" alt="installed result"/>

    <p>In this tutorial, we will create a project type that
    will look as follows in the Projects window:</p>

    <p><img border="1" src="../../images/tutorials/projecttypes/demo-6.png" alt="installed result"/>

    <p>Our project type will be defined by specific entries
        in the project's <tt>project.xml</tt> file. The "Build Project"
        menu item, shown in the screenshot above,
        will call the "compile" target in the "build.xml"
        file, both of which are assumed to be present.

    <p>The following are the main NetBeans API classes
        we will be implementing in this tutorial:

      <table>
        <tbody>
            <tr>
                <th class="tblheader" scope="col">Class</th>
                <th class="tblheader" scope="col">Description</th>
            </tr>
            <tr>
                <td class="tbltd1"><tt><a href="http://bits.netbeans.org/dev/javadoc/org-netbeans-modules-projectapi/org/netbeans/api/project/Project.html">org.netbeans.api.project.Project</a></tt></td>
                <td class="tbltd1">Represents the project.</td>
            </tr>
            <tr>
                <td class="tbltd1"><tt><a href="http://bits.netbeans.org/dev/javadoc/org-netbeans-modules-projectuiapi/org/netbeans/spi/project/ui/LogicalViewProvider.html">org.netbeans.spi.project.ui.LogicalViewProvider</a></tt></td>
                <td class="tbltd1">Provides the logical view for the project.</td>
            </tr>
            <tr>
                <td class="tbltd1"><tt><a href="http://bits.netbeans.org/dev/javadoc/org-netbeans-modules-projectapi/org/netbeans/api/project/ProjectInformation.html">org.netbeans.api.project.ProjectInformation</a></tt></td>
                <td class="tbltd1">Provides supplemental information for the project.</td>
            </tr>
            <tr>
                <td class="tbltd1"><tt><a href="http://bits.netbeans.org/dev/javadoc/org-netbeans-modules-projectuiapi/org/netbeans/spi/project/ui/support/NodeFactory.html">org.netbeans.spi.project.ui.support.NodeFactory</a></tt></td>
                <td class="tbltd1">Provides one or more nodes for the logical view.</td>
            </tr>
            <tr>
                <td class="tbltd1"><tt><a href="http://bits.netbeans.org/dev/javadoc/org-netbeans-modules-projectapi/org/netbeans/spi/project/ActionProvider.html">org.netbeans.spi.project.ActionProvider</a></tt></td>
                <td class="tbltd1">Provides one or more actions for the project.</td>
            </tr>
        </tbody>
    </table>

        <p>At the end of this tutorial, your
         module source structure will be as follows:</p>
    
    <p><img border="1" src="../../images/tutorials/projecttypes/demo-7.png" alt="New Sample"/>
    
    <h2 class="tutorial"><a name="creatingthemoduleproject"></a>Creating the Module Project</h2>
    
        <p>We begin by working through the New Module Project
            wizard. At the end of it, we will have a basic
            source structure, with some default files, that
            every NetBeans module requires.

            <ol>
    <li>Choose File &gt; New Project (Ctrl+Shift+N). Under Categories, select NetBeans Modules.
        Under Projects, select Module. Click Next.</li>
    <li>In the Name and Location panel, type <tt>DemoProjectType</tt> in the Project Name field.
        Change the Project Location to any directory on your computer. Leave the Standalone Module option
        and Set as Main Project checkbox selected. Click Next.</li>
    <li>In the Basic Module Configuration panel, type <tt>org.netbeans.demo.project</tt>
     in Code Name Base.
    <li>Do not select "Generate XML Layer", since our module
        will not need a <tt>layer.xml</tt> file. Leave the
        location of the localizing bundle 
        so that it will be stored in a package with
        the name <tt>org/netbeans/demo/project</tt>. Click Finish.</li>
</ol>
    
    <p> The IDE creates the <tt>DemoProjectType</tt>
        project. The project contains all of your sources and
        project metadata, such as the project's Ant build script. The project
        opens in the IDE. You can view its logical structure in the Projects window (Ctrl-1) and its
    file structure in the Files window (Ctrl-2).

    <h2><a name="settingdependencies"></a>Setting Dependencies</h2>
        <p>We will need to make use of several NetBeans APIs. In this
        step, we select the modules that provide the NetBeans APIs
        that we will need.
            
            <ol>
            
            <li>Right-click the project node and 
        choose Properties. The Project Properties dialog box opens.</li>
        <li>In the Libraries panel, add dependencies on the
        following modules:
        
        <p><ul>
            <li>Ant</li>
            <li>Ant-Based Project Support</li>

            <li>UI Utilities API</li>
            <li>Utilities API</li>
        </ul>
        
        <li><p>Expand the module's
             Libraries node
             in the Projects window
             and make sure that the
        list of APIs is as shown in the

     <!-- ===================================================================================== -->
            <h2><a name="creatingthenodes"></a>Creating the Nodes</h2>
            <p>Next, we work some more with the <tt><a href="http://bits.netbeans.org/dev/javadoc/org-netbeans-modules-projectuiapi/org/netbeans/spi/project/ui/support/NodeFactory.html">org.netbeans.spi.project.ui.support.NodeFactory</a></tt>

            <p>At the end of this section, when you open a folder containing
                 a <tt>project.xml</tt> file as specified above, all the folders
                 and files will be shown in the Projects window, just like the
                 Files window, as shown below:

                <p><img border="1" src="../../images/tutorials/projecttypes/demo-5.png" alt="New Sample"/>

                <p>In subsequent sections, we'll filter the display in the Projects
                     window. For now, we'll simply show everything the project
                     provides.

                <p>Do the following:

                <ol>
                <li><p>Replace <tt>DemoNodeFactory</tt> with the following:</p>

</pre>

<p><li>Next, we look for the "nbproject" folder in our application and create a <tt>FilterNode</tt>
         for that folder, so we can display it in the logical view of the project.

         <p>Create a new class called <tt>DemoFilterNode</tt> and define it as follows:</p>

<pre class=examplecode>public class DemoFilterNode extends <a href="http://bits.netbeans.org/dev/javadoc/org-openide-nodes/org/openide/nodes/FilterNode.html">FilterNode</a> {

    }

    @Override
    public String getDisplayName() {
        return "Important Files";
    }

    //Next, we add icons, for the default state, which is
    //closed, and the opened state; we will make them the same.
    //Icons in project logical views are
    //based on combinations--you must combine the node's own icon
    //with a distinguishing badge that is merged with it. Here we
    //first obtain the icon from a data folder, then we add our
    //badge to it by merging it via a NetBeans API utility method:
    @Override
    public Image getIcon(int type) {
        DataFolder root = DataFolder.findFolder(FileUtil.getConfigRoot());
        Image original = root.getNodeDelegate().getIcon(type);
        return ImageUtilities.mergeImages(original, smallImage, 7, 7);
    }

    @Override
    public Image getOpenedIcon(int type) {
        DataFolder root = DataFolder.findFolder(FileUtil.getConfigRoot());
        Image original = root.getNodeDelegate().getIcon(type);

</pre>


         <li><p>Install the module again and you should see the "nbproject" folder

            <p>Finally, we add a new menu item to the project's contextual menu.
