NavigationManager

The nagivation manager allows you to:

• Lookup Dockable UI wrappers for Navigable UI content
• Add listeners to intercept addition/removal of Navigable content from the UI
  • Move operations fire a removal then addition

Looking up dockables

The Dockable type represents a docking tab shown in the UI that holds some content. In this case the only kind of content that can be looked up is Navigable content. A Navigable UI element is one that represents something in the Workspace referencable by a PathNode. This would include classes, files, etc.

Dockable dockable = navManager.lookupDockable(myNavigable);
if (dockable != null) {
    // TODO: Do things with the dockable
}

Listening to navigable changes

Listening to when Navigable content lets you track what kinds of content is being displayed in Recaf.

addNavigableAddListener(navigable -> {
    // You may want to react based on what kind of content is being added.
    if (navigable.getPath() instanceof ClassPathNode cp) {
        // TODO: Operate on removed navigable
    }
    
    // Another option for checking the content type, do an instanceof on the navigable.
    if (navigable instanceof ClassNavigable cn) {
        // ...
    } else if (navigable instanceof FileNavigable fn) {
        // ...
    }
});
addNavigableRemoveListener(navigable -> {
    // TODO: Operate on removed navigable
});
