The QStyleOptionTabV2 class is used to describe the parameters necessary for drawing a tabs in Qt 4. or above. An instance of the QStyleOptionTabV2 class has type SO_Tab
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 QStyleOptionTab
and QStyleOptionTabV2. One way to achieve this is to use the QStyleOptionTabV2 copy constructor. For example:
QStyleOptionTab tabOption = null;
if ((tabOption = (QStyleOptionTab) option) != null) {
QStyleOptionTabV2 tabV2 =
new QStyleOptionTabV2(tabOption);
// draw the tab using tabV2
}
In the example above: If tabOption's version is 1, the extra member (iconSize) will be set to an invalid size for tabV2. If tabOption's version is 2, the constructor will simply copy the tab's iconSize. For an example demonstrating how style options can be used, see the Styles example.

QStyleOptionTabV2
public QStyleOptionTabV2()
- Constructs a QStyleOptionTabV2.
QStyleOptionTabV2
public QStyleOptionTabV2(QStyleOptionTab other)
- Constructs a QStyleOptionTabV2 copy of the other style option which can be either of the QStyleOptionTabV2 or
QStyleOptionTab
types. If the other style option's version is 1, the new style option's iconSize is set to an invalid value. If its version is 2, its iconSize value is simply copied to the new style option.
QStyleOptionTabV2
public QStyleOptionTabV2(QStyleOptionTabV2 other)
- Constructs a copy of the other style option.
setIconSize
public final void setIconSize(QSize iconSize)
- This variable holds the size for the icons. The default value is
QSize
(-1, -1), i.e. an invalid size; use QStyle::pixelMetric()
to find the default icon size for tab bars. - See also:
QTabBar::iconSize()
.
iconSize
public final QSize iconSize()
- This variable holds the size for the icons. The default value is
QSize
(-1, -1), i.e. an invalid size; use QStyle::pixelMetric()
to find the default icon size for tab bars. - See also:
QTabBar::iconSize()
.
clone
public QStyleOptionTabV2 clone()
- This method is reimplemented for internal reasons
- Overrides:
