    public class QStyleOptionTabV2

extends QStyleOptionTab
implements java.lang.Cloneable

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.

Constructor Detail

### 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.

Method Detail

### 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:
    `clone` in class `QStyleOptionTab`
