How much resources does an app use if it's in the background?

Hi,

if I create a native app, does egui render the GUI even if the app isn't active?

For example, if I have an app that shows statistics, but I only check the app from time to time, will I still pay the full cost as if I'm interacting with the app, even if the app is in the background on a different workspace?

Best regards,
Daniel

By default, no. egui widgets need to announce their intention to redraw by calling request_repaint() on the context reference. This is only necessary if the widgets are performing animations. Otherwise, egui only responds to input events like pointer movements and key presses.

Thanks for answering my question, @parasyte!
