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 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 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 = 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.

public QStyleOptionFrameV2()
QStyleOptionFrameV2
object.
public QStyleOptionFrameV2(QStyleOptionFrame other)
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.
public QStyleOptionFrameV2(QStyleOptionFrameV2 other)
QStyleOptionFrameV2
copy of the other style option.
