public class QStyleOptionFrameV2

The QStyleOptionFrameV2 class is used to describe the parameters necessary for drawing a frame in Qt 4. 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 typeSO_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 do not 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 = new QStyleOptionFrame();

        QStyleOptionFrame frameOption = null;
        if ((frameOption = (QStyleOptionFrame) option) != null) {
            QStyleOptionFrameV2 frameOptionV2 = new QStyleOptionFrameV2(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.

Constructor Detail

QStyleOptionFrameV2

public QStyleOptionFrameV2()
Constructs a QStyleOptionFrameV2 object.


QStyleOptionFrameV2

public QStyleOptionFrameV2(QStyleOptionFrame other)
Constructs a QStyleOptionFrameV2 copy of the other style option which can be either of the QStyleOptionFrameV2 or QStyleOptionFrame types.

If the other style option's version is 1, the new style option's FrameFeature value is set to QStyleOptionFrameV2::None . If its version is 2, its FrameFeature value is simply copied to the new style option.

version.


QStyleOptionFrameV2

public QStyleOptionFrameV2(QStyleOptionFrameV2 other)
Constructs a QStyleOptionFrameV2 copy of the other style option.
