Cleanup some minor issues in the chart example: - remove unused members - use initializer list for members - pass a proper role to dataChanged() - honor roles parameter in PieView::dataChanged() - use nullptr instead 0 - use new-style connect - fix indentation and other whitespaces Change-Id: Idb212b07c006fe3ae31bee9cd9b1ba4d03043b5e Reviewed-by: André Hartmann <aha_1980@gmx.de> Reviewed-by: Paul Wicking <paul.wicking@qt.io>
