| Demonstrates combining Qt and tornado, both which want to have their own event loop. | |
| The solution is to run tornado in a thread, the issue is that callbacks will then also be executed in this thread, and Qt doesn't like that. | |
| To fix this, I show how to use execute the callback in the main thread, using a Qt signal/event in combination with Promises. | |
| The output of the program is: | |
| fetch page, we are in thread <_MainThread(MainThread, started 47200787479520)> | |
| response is 191548 bytes, we are in thread <Thread(Thread-1, started daemon 47201018689280)> | |
| the other thread should fulfil the result to this promise, we are in thread <Thread(Thread-1, started daemon 47201018689280)> |
