webGlEvent for click outside node

Hi, thankcs for the precious help you use to provide me, I come with another question:

Is there any way to register the event of a click outside a node, I mean a click in the void space?

I want to highlight the related nodes when I click in a node, but I want to unhighlight them when clicking in the void space.

Any ideas?

Thank you very much!

Start by locating the WebGL event-handling entry point and how node clicks are currently detected. Define a way to distinguish clicks on a node from clicks in empty space, then verify that node highlighting can be cleared for the empty-space case.
