The option parameter is a pointer to a QStyleOptionComplex object that can be cast to the correct subclass using the qstyleoption_cast() function. Note that the rect member of the specified option must be in logical coordinates. Reimplementations of this function should use visualRect() to ...
queryable and designable object properties. Hierarchical and queryable object trees that organize. Object ownership in a natural way with guarded pointers (QPointer). A dynamic cast that works across library boundaries.Qt QML is a module that provides a framework for developing applications and librari...
This signal is emitted when the widget that has keyboard focus changed from old to now, i.e., because the user pressed the tab-key, clicked into a widget or changed the active window. Both old and now can be the null-pointer. The signal is emitted after both widget have been notified...

have been made. Probably most notable is the internal switch from QWeakPointer to QPointer, because it gets rid of deprecated Qt functionality. This allows QCustomPlot to be compiled with Qt 5.1 and Qt 5.2 smoothly (although only the beta of Qt 5.2.0 was tested at the time of this ...
Although the size() is 5, the byte array also maintains an extra '\0' character at the end so that if a function is used that asks for a pointer to the underlying data (e.g. a call to data()), the data pointed to is guaranteed to be '\0'-terminated....
Returns the givenvalueconverted to the template typeT. This works with any typeTthat has aQMetaType. The conversion is done in JavaScript semantics. Those differ fromqvariant_cast's semantics. There are a number of implicit conversions between JavaScript-equivalent types that are not performed by...
