|1= One concern I have though, from the discussions over the last year, is that the PUI->Qt migration plan is not a direct one-to-one migration. I.e. to have a main Qt window providing the main FlightGear window by containing a top menu bar followed by a QtWindow GL widget underneath, in which the FG main execution loop is run as a thread from within the Qt main loop. My impression was that the GUI will be a secondary window or dialog that you have to switch to. But one problem I see with this design is that all modern GUI toolkits (Qt, GTK, metro, Cacoa, Carbon, etc.) suffer from racing and segfaulting issues if the GUI main thread or main loop/event handler is not thread number 1. | |||
