Testing in #1242 confirms that the Ubuntu menu+icon issue is solved by these changes. |
Move AppInit2 and Shutdown to a thread. This allows a more responsive splash screen, prevents 'process does not respond' messages from the window system and will allow for showing a user friendly window while shutting down.
Makes it clear to the user that the application is still wrapping up and the computer should not be turned off until it is finished.
Remove the need for global references `guiref` and `splashref` by making the BitcoinGUI and SplashScreen classes register for the UI interface signals themselves.
Stop the shutdown timer from exiting the main loop when shutdown is already in progress. Fixes seeming hanging window after typing 'stop' in debug console. Also hide the debug console during shutdown as it is useless without a core to connect to.
