Ignore click on window?

I have a situation where I’m floating a transparent window overtop of a plugin so that I can paint ontop of it, however I’d like the user to be able to click and have the mouse event propagated so that they can still move the knobs and sliders on the UI of the plugin. Is this possible?

I’ve tried setInterceptsMouseClicks on the transparent window or it’s component, I’ve tried manually forwarding mouseDown/Up/Drag events to the editor and to the editor’s window, and I’ve tried using addMouseListener(…) to the editor but nothing seems to work.

There must be a way to do this but I’m a bit stumped… appreciate any advice!
