## Detailed Description

QStyleOptionTabWidgetFrame contains all the information that QStyle functions need to draw the frame around QTabWidget.

For performance reasons, there are few member functions and the access to the member variables is direct (i.e., using the `.` or `->` operator). This makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.

See also QStyleOption and QTabWidget.

## Member Type Documentation

### enum QStyleOptionTabWidgetFrame::StyleOptionType

This enum is used to hold information about the type of the style option, and is defined for each QStyleOption subclass.

Constant | Value | Description
--- | --- | ---
`QStyleOptionTabWidgetFrame::Type` | `SO_TabWidgetFrame` | The type of style option provided (SO_TabWidgetFrame for this class).

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.

See also StyleOptionVersion.

### enum QStyleOptionTabWidgetFrame::StyleOptionVersion

This enum is used to hold information about the version of the style option, and is defined for each QStyleOption subclass.

Constant | Value | Description
--- | --- | ---
`QStyleOptionTabWidgetFrame::Version` | `1` | 2

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.

See also StyleOptionType.

## Member Variable Documentation

### QSize QStyleOptionTabWidgetFrame::leftCornerWidgetSize

This variable holds the size of the left-corner widget

The default value is QSize(-1, -1), i.e. an invalid size.

### int QStyleOptionTabWidgetFrame::lineWidth

This variable holds the line width for drawing the panel

The default value is 0.

### int QStyleOptionTabWidgetFrame::midLineWidth

The default value is QSize(-1, -1), i.e. an invalid size.

### QRect QStyleOptionTabWidgetFrame::selectedTabRect

This variable holds the rectangle containing the selected tab

This rectangle is contained within the tabBarRect. The default value is a null rectangle, i.e. a rectangle with both the width and the height set to 0.

### QTabBar::Shape QStyleOptionTabWidgetFrame::shape

This variable holds the tab shape used to draw the tabs

The default value is QTabBar::RoundedNorth.

### QRect QStyleOptionTabWidgetFrame::tabBarRect
