Outline View
While the Project Explorer provides an easy way to find, select, and open project resources, the Outline view provides a quick and convenient way to navigate within a particular model, such as a form.
If the Outline view is not visible, open it by selecting . (If Outline is not among the view choices, click .)
The default area for the Outline view is the lower left corner of the Eclipse workbench but, as with other views, it can be moved to another area by dragging its title bar.
There are two modes for using the Outline view: as a hierarchical tree with expandable nodes, or as a thumbnail graphical image of the form. You can switch between the two modes by clicking the button for the desired mode in the upper right corner of the Outline view.
