Mac: Crash with save dialogs running Snow Leopard package on Mountion Lion

[Martyn Gigg]

As we still only have one Mac package it is imperative that this works on Mountain Lion when using the Snow Leopard package.

To reproduce on a ML machine:

• Start MantidPlot
• Go to File->Save Project As
• Click the spinbox used to select the directory for saving -> CRASH

[Martyn Gigg]

Note this happens for all save dialogs but not the load dialogs

[Martyn Gigg]

Use native save dialogs for OSX running 10.6 package on 10.8. Re #6497

This changes all uses of getSaveFileName to a custom handler that we already had so that we can switch to Qt dialogs where necessary.

This is a far from ideal fix but crashing is certainly worse.

Ticket #6501 has been opened to investigate whether a newer Qt will help.

Tester: Please try and install the snow leopard package on a SL machine and on a ML machine. On SL you should see a standard Mac save dialog and on ML you should see a different Qt save dialog that more importantly doesn't crash!

Do you want me to wait for the new 'release kit' or grab the latest incremental one ?

[Martyn Gigg]

The incremental one should be fine I think.

[Stuart Campbell]

I do indeed see a Mac OS X native dialog on Snow Leopard and a Qt one on Mountain Lion (and no crash).
