Re: [PyQt] Mac OS X Problem: PyQT applications not focusing on launch

Cheers, Holger Given it's a Mac-only problem, which wasn't reproducible with Qt, only PyQt, for me it looks like a PyQt bug. But the fix is quite easy. A.

Maybe somewhere in the PyQt Wiki: http://www.diotavelli.net/PyQtWiki/StartPage Perhaps create a Platform Specific Notes page and add a link to it in the list under Developing with PyQt and PyKDE on the main page.

But the fix is quite easy. No, it's not a PyQt issue, it's about Qt being compliant with Apple design guidelines.. (red that in some Qt developer blog, but didn't remember the address..) I bet, wxpython does ignore these guides and implicitely raises the window. Now imagine, you try to respect them with wx.. Calling raise_() is a small price to pay, doesn't it? Pete A.
