The %ls escape sequence expects a pointer to a zero-terminated array of unicode characters of type char16_t, or ushort (as returned by QString::utf16()). This is at odds with the printf() in the standard C++ library, which defines %lc to print a wchar_t and %ls to print a wchar...
isNull(); // returns false QString("abc").isEmpty(); // returns false All functions except isNull() treat null strings the same as empty strings. For example, toUtf8().constData() returns a pointer to a '\0' character for a null string (not a null pointer), and QString() ...

If unset, or if a null QRectF is set, this property has the same value as QGraphicsScene::sceneRect, and it changes with QGraphicsScene::sceneRect. Otherwise, the view's scene rect is unaffected by the scene. Note that, although the scene supports a virtually unlimited size, the range...
