Hi, I am new to here. I need to know if the main window is minimised.  
Full problem: I have a multi window G4P project and if the main window is minimized, I want to minimize others(G4P windows), I want them to act as one window when minimizing and maximizing.  
I have found [this](https://forum.processing.org/two/discussion/1899/loading-images-in-g4p-windows) on the old forum, am not sure if this question has already appeared on the new forum. The problem is that [frame.getExtendedState()](https://forum.processing.org/two/discussion/1899/loading-images-in-g4p-windows) doesn’t work, I’m using Processing v 3.5.4.
