Ladybird: Allow posting events to the Qt event loop from other threads Previously, a QTimer was used to start processing of our event queue in the main Qt event loop. Unfortunately, QTimers are not thread-safe, and disallow starting of a timer from a different thread than it was created in. Instead, use a dummy QObject to post a custom QEvent to the main loop from whatever thread we like, and process our event queue when it is received by our dummy object. 2023-07-04 04:37:36 -05:00			`/*`
