Adapting plugin to assign hotkey for the "scroll from source" action in the Unity Explorer

[SugoiDev]

I use this plugin to assign a keyboard hotkey to the "scroll from source" action. It works fine with the normal solution explorer, but not with the Unity Explorer.

It's a very small plugin and the relevant part of the code for the selection is this

ProjectViewImpl projectView = (ProjectViewImpl) ProjectView.getInstance(myProject);
AbstractProjectViewPane currentProjectViewPane = projectView.getCurrentProjectViewPane();
if (currentProjectViewPane != null) {
    SelectInTarget target = currentProjectViewPane.createSelectInTarget();
    if (target != null && target.canSelect(selectInContext)) {
        target.selectIn(selectInContext, false);
    }
}

I want to implement support for the Unity Explorer in this plugin.
For that, I have a few questions:

1. How to query to determine which explorer is currently being used?
2. How to get the AbstractProjectViewPane that represents the Unity Explorer? I thought getCurrentProjectViewPane would already work for that, but it returns the normal explorer even when the Unity Explorer is being used.

Alternatively, is there a method to get a AbstractProjectViewPane that respects the Unity Explorer and would work uniformly with both explorer views, depending on which one is visible?

Thanks for reading.

Hmm this code actually should work. At least with FileSelectInContext.
We have UnityExplorerSelectInTarget class, you can take a look.

In the latest nightly, the behavior changed: it now only works in the Unity Explorer, and will throw errors if the normal solution explorer is visible instead.

For anyone curious, below is the exception that is thrown.
I'll close this issue now, since it is working with the Unity solution explorer.

Just removed the @NotNull attribute and it compiled and is now properly working with both solution explorer views.

If anyone is interested, I attached a working build on the original repository here: luonanqin/intellij-idea-plugins/issues/10

Ok thanks for information =)
