详细描述
The QStyleOptionTabWidgetFrame class is used to describe the parameters for drawing the frame around a tab widget.
QStyleOptionTabWidgetFrame contains all the information that QStyle functions need to draw the frame around QTabWidget.
For performance reasons, the access to the member variables is direct (i.e., using the . or -> operator). This low-level feel makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.
For an example demonstrating how style options can be used, see the Styles example.
参见 QStyleOption and QTabWidget.
成员类型
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.
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 | 2 | 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.
参见 StyleOptionType.

成员变量
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
This variable holds the mid-line width for drawing the panel
The mid line width is usually used in drawing sunken or raised frames. The default value is 0.

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
This variable holds the rectangle containing all the tabs
