[Qgis-user] Mac QGIS using Qt4.5

[John C. Tull]

I'll just disable grass for now as I do not want to compile qt-4.5  
myself. I'm more interested in the improvements to open/save dialogs  
and testing those.

The patch applied successfully, but the build failed. I went back  
through some of the ts files one at a time as errors popped up during  
make and deleted more problematic lines. Apparently some additional  
changes to those since you created your patch. I'm using the most  
current source. The build succeeded from there, but I've no idea what  
effect these changes have on the translations.

I guess we now need someone to fix qgsgrassshell.cpp to drop the qt3  
dependency. That and somehow handle the qt-4.5 issues with the  
translations without the need to patch or hand edit them.

Thanks!
John
