All, I just submitted an update to backend_qt.py and backend_qt4.py. Both updates remove the 'mainloop' flag from the 'show' function as it is now handled automatically.
Essentially the qt event-loop will only be started by matplotlib if matplotlib was the one to create the qApp, if not then it is up to the creator of the Qt qApp to start the event-loop when they are ready for it. This allows for applications with embedded Qt event loops to work with matplotlib. I have run some test cases in a few different python environments (including the vanilla python) and all seem to be working. I have not, however tested this in the iPython environment (although I don't think that iPython uses Qt, does it?). Any feedback would be appreciated. --James Evans ------------------------------------------------------------------------- Take Surveys. Earn Cash.
