Hi, Actuallly i solved my problem but i have another one. I am sending file in while loop, as you said before it doesnt send data pyhshically, i am updating my progressBar in while loop, so the progressBar is being updated before data being sent.. Is there any signal that self.transport.write() creates when data "really" sent? May be i can update my progressBar with that signal.. Thanks.. -adige- 2008/12/2 Jean-Paul Calderone

Hi, i am using qt4reactor with twisted. My app structure is below:

i have pyqt class

[snip]

i am updating my progressBar from Upload class, but window is freezing when i do it (only progressBar isnot, others are freezing when i upload file). How can i solve this, how can i design it?

You've probably omitted too many details for anyone to know what is causing the problem or make a suggestion about how to fix it. Try posting a complete, minimal example which demonstrates the problem so that others can reproduce it themselves.

Sort of. You shouldn't call transport.write() in a loop, you should register a producer for the transport and call transport.write when it's ready. Documentation is here: http://twistedmatrix.com/projects/core/documentation/howto/producers.html
