I have a Samsung Galaxy Tab 10.1 running a CM9 ICS rom. The tab lacks a removable micro sd card like most devices in the category and so I can't use UMS protocol and have to use the now default MTP. I know that an MTP KIO-slave is in the works and I know I can expect it in KDE 4.10 but in my experience I have never had a MTP implementation that works easily (MTP is an odd protocol) and I am also a little impatient. Anyhow, I decided to write a quick python app with GUI (in pyqt4) to make life easy.
So the program is fairly simple. It basically allows drag-drop of files on to a QListWidget which then displays them and sets links up for the webserver to use. The webserver can be started and stopped as needed. The idea is then that I can just point my browser at the IP:Port combination and just download them. So ayways, I just can't get a way to set-up the threading so that I can actually stop and restart the thread. I've found some great articles on the web but I just find threads very confusing.
I have a feeling that .serve_forever() is the problem because it causes an infinite loop but what else am I to use especially considering that I want to handle multiple requests.
So here is my code:
Program:
*The commented out code is really just to show my different attempts. The uncommented bit is what currently threads and the server starts and doesn't block the UI but how do I start and stop/pause the thread.
UI:
Warning: This will create a folder in your home directory called fileshare. The self clean-up hasn't been implemented yet.
I know this might not be the best place to ask but I've always found good assistance here when I have been at my wits end and don't feel like being berrated for poor coding style/being an imbecile etc. This isn't supposed to be a very powerful program, just a simple something that I can give people when they struggle with quickly and easily sending files and don't want to set-up a big file server etc. I'm going to make it show the needed URL to type into a browser to get the files.
Thanks for any help you guys can give! Appreciate it a ton!
P.S. I usually just invoke
and work with that. The limitation with this is that you have to run it in the folder you want to share and its difficult to to have multiple sources.
