why you need this feature?
GUI can be run only from main thread

My application implement a thread based httpserver. One service is to select a file and get the path. -

you can send a signal to the gui when the server receives requests. the gui can open the dialog and send back the path.
The problem is to handle correctly the requests timeout. HTTP has special code (IIRC 100) for long operation

Hi,
That sounds a bit like reverse logic. Can you explain your application work flow ?
