Hi NetBeans users, I need some advice on Explorer Views and Nodes, in particular FilteredNode. Abstractly, my scenario is the following:
The data model is a simple collection of beans with with properties
"key", "left", and "right", represented as a tree of Nodes (dummy root
Node with BeanNode children). Now, in a TopComponent I want to show
*two* explorer views: The left-hand explorer view should be an
OutlineView showing all Nodes whose "left" property is non-null, the
right-hand explorer view should show all Nodes whose "right" property is
non-null.
In crude ASCII art:
Key | Left Key | Right
a | 1 a | 3
b | 2 c | 4
So, Nodes can show up in both views (like the one with key "a"), but
that need not be the case ("b", "c").
I imagine that my TopComponent will be an ExplorerManager.Provider for
the unfiltered view. Then the two OutlineViews will need
ExplorerManagers of their own, having some kind of FilteredNode as their
root node. Is this the correct way to think about this issue? And if so,
how would one publish the selected Node (which may or may not be shown
in both views, in the global lookup?
Any pointers are greatly appreciated. (And, no, merging the two views
into one is not an option; the actual UI is more complex than the above
sketch.)
Best wishes,
Andreas
