The context pointer was dereferenced after the context object was deleted. This is fixed by storing a pointer to the MainWindow in QTFullScreen, so context does not have to be dereferenced.
The logic in QTFullScreen::eventFilter is also simplified a bit.
Decoupled classes from MainWindow to reference Context
and Athlete (and introduced a couple of new headers).
We no longer pass around a MainWindow pointer to children
but pass a context instead.
There are still a few pieces left in MainWindow that need
to move to a better place;
* Setting/clearing filter selection
* Working with Intervals
* Adding/Deleting Rides
* Save on Exit
As mentioned previously there are lots of other parts to
this refactor left to do;
* break MainWindow Gui elements into Toolbar and Views
* migrate from RideItem and Ridelist to ActivityCollection
and Activity classes that are not tied into gui elements.
* introduce Application Context and AthleteCollection
Add support to toggle full screen mode on Linux
and Windows, in similar fashion to the recent
update for Mac OSX Lion.
A new view menu option to toggle full screen has
been added in lieu of the Mac titlebar icon on
either Win/Linux. Additionally, hitting Function
key F11 toggles fullscreen and hitting ESC whilst
in full screen also returns to normal.
