Fix Creator crash when opening Charts project...
Fix Creator crash when opening Charts project There's a problem with Creator parsing the headers defined in Charts src.pro. This will cause the Creator (3.0.0-beta) to crash when trying to open charts.pro. As a workaround the headers are defined using new variables for each function and unsetting the variables after each rotation.
