Recipe 13.4 Creating a Plug-in That Supports Views

13.4.1 Problem

You need your plug-in to support a view.

13.4.2 Solution

Use the PDE template "Plug-in with a view."

13.4.3 Discussion

This next example will build a plug-in that supports a view—in this case, a clickable tree of items. To follow along, create a new plug-in project named org.cookbook.ch13.ViewPlugIn. In the Plug-in Code Generators dialog, shown in Figure 13-9, select "Plug-in with a view" and click Next.

In the next dialog, set the provider name to Eclipse Cookbook, as shown in Figure 13-10.

Clicking Next brings up the Main View Settings dialog shown in Figure 13-11. Here's where you customize the view, setting its name, as well as a whether it should be a tree-based view or a table-based view. Name the view Item View, and make it a tree-based view, as shown in the figure. Click Next again to bring up the final dialog of this wizard.

In the last dialog, you configure the view's actions. Leave the defaults selected, and click Finish to create the template for this plug-in (see Figure 13-12).

After you click Finish, the template for this plug-in is created, and these files are created and added to the project's src folder:

org.cookbook.ch13.ViewPlugIn
|
|_  _  _build.properties                          Controls the build script
|
|_  _  _plugin.xml                                Plug-in manifest
|
|_  _  _src                                       Source folder
    |
    |_  _org.cookbook.ch13.ViewPlugIn 
    |   |_  _ViewPlugInPlugin.java              Plug-in's Java file
    |
    |_  _org.cookbook.ch13.ViewPlugIn.views
        |_  _SampleView.java                    View's code

To customize this new plug-in by adding items to the view and making them do something, see the next two recipes.
