Q_DECL_OVERRIDE (which expands to 'override' for supported compiler) helps to declare the intent (that it is an overridden function) and force compilation error when there is no such virtual function in the base class. The examples should show the best practice of having it, as it may save the programmer quite some time in case of change of API or typo in the function name or arguments. This change was done automatically with clang-modernize -add-override -override-macros And fixed MSVC compilation by removing inline for TorrentViewDelegate::paint Change-Id: Ice66ae93fae571266f908703d5b8892b2c1ebb1a Reviewed-by: Jędrzej Nowacki <jedrzej.nowacki@digia.com>
