The Selection / Navigation
Window will be displayed on the top portion of the Left Panel when there
is data loaded or created in ParaView, the Left Panel is not hidden, and
a Source or Filter property sheet is currently displayed in the Left Panel.
The Selection / Navigation Window will appear similar to the example shown
on the right.
The title of the Selection / Navigation Window and the status of the two radio buttons indicate the current mode. In the example above, the first radio button (showing a list) is depressed and the title of the window is Selection Window. The Selection Window presents a list of all data objects in ParaView, allowing you to select the active one and view / control the visibility of each data object.
If the second radio button (showing a pipeline diagram) is depressed, the title would be Navigation Window. The Navigation Window presents a piece of the pipeline diagram for the current data objects and allows you to select the active one. These two types of windows are covered in more detail in the next two sections.
