Whilst reviewing some Qt C++ code I came across this: class Foo { Q_OBJECT signals: virtual void someSignal(const QString& str, int n) { Q_UNUSED(str); Q_UNUSED(n); } ... }; Now, Qt signals cannot have a body so I'm surprised this even compiles (perhaps because the body is effectively empty). I also don't see the p...

Using Qt 4.6.3 on Linux/X11. I have a QTreeView widget which uses a QStandardItemModel as its model, with 4 columns and hundreds of rows.
