Upgrading to PyQT4
« on: March 07, 2009, 06:47:59 am »
I have an app I want to run that needs PyQT4.

Would it be possible on VL6 to upgrade from PyQT3 without making the system unstable?

The worst thing that can happen is some app depending on PyQt3 not working anymore.
I have been working in a PyQt4 package, which I am testing before I submit it for the repository.
You are welcome to give it a try: http://drop.io/k3woxwp

That's my fear!  ;D

How reversible do you think installing pyqt4 would be?

Or best until it gets to stable?

PyQt4 is stable here, and I am afraid that Qt3 apps will never be compatible with Qt4 ones, that is, Qt4 will not include backward compatibility with Qt3. The developers will have to port their apps to Qt4 if they want. Qt3 and Qt4 can live together very well though, but not the Python bindings as far as I know, I have been looking at this and I didn't find a way to make them work together, and worst, nobody seems to be worried about it. The good thing in all this seems to be that there is not many apps written for PyQt, at least in our repo.

EDIT: Well I did a search in the repo and looks like we have 0 apps depending on PyQt3, that means that the risk is also 0 :P

Above and beyond the call of duty!

Had to upgrade QT4 as well and everything seems to be holding together!
