how to select file from a QThread

[mcosta]

why you need this feature?

GUI can be run only from main thread

@mcosta yep, this is the problem :(
My application implement a thread based httpserver. One service is to select a file and get the path.

why multi-thread gui for that??

@mcosta the thread open the socket and read http request, and should get back the response..... in this case the path of a selected file!!! any tips?

[mcosta]

http requests shall be served in few seconds otherwise you can have timeout.

[mcosta]

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

A Gui widgets can only use it in main thread but you can use Signal-Slot with Qt::QueedConnexion if you want your widget d'ont freeze

Hi,

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