public class QStyleOptionFrameV2
The QStyleOptionFrameV2 class is used to describe the parameters necessary for drawing a frame in Qt 4.1 or above.
QStyleOptionFrameV2 inherits QStyleOptionFrame which is used for drawing several built-in Qt widgets, including QFrame, QGroupBox, QLineEdit, and QMenu.
An instance of the QStyleOptionFrameV2 class has type SO_Frame and version 2. The type is used internally by QStyleOption, its subclasses, and qstyleoption_cast() to determine the type of style option. In general you do not need to worry about this unless you want to create your own QStyleOption subclass and your own styles. The version is used by QStyleOption subclasses to implement extensions without breaking compatibility. If you use qstyleoption_cast(), you normally don't need to check it.
If you create your own QStyle subclass, you should handle both QStyleOptionFrame and QStyleOptionFrameV2. One way to achieve this is to use the QStyleOptionFrameV2 copy constructor. For example:
QStyleOptionFrame *option;
if (const QStyleOptionFrame *frameOption =
qstyleoption_cast<const QStyleOptionFrame *>(option)) {
QStyleOptionFrameV2 frameOptionV2(*frameOption);
// draw the frame using frameOptionV2
}
In the example above: If the frameOption's version is 1, FrameFeature is set to None for frameOptionV2. If frameOption's version is 2, the constructor will simply copy the frameOption's FrameFeature value.
For an example demonstrating how style options can be used, see the Styles example.
