详细描述

The QStyleOptionFrame class is used to describe the parameters for drawing a frame.

QStyleOptionFrame is used for drawing several built-in Qt widgets, including QFrame , QGroupBox , QLineEdit ，和 QMenu .

An instance of the QStyleOptionFrame class has type SO_Frame and version 3.

类型内部使用通过 QStyleOption ，其子类，和 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 子类以实现扩展在不破坏兼容性的情况下。若使用 qstyleoption_cast ()，通常不需要校验它。

对于可以如何使用样式选项的演示范例，见 样式 范例。

enum QStyleOptionFrame:: FrameFeature
flags QStyleOptionFrame:: FrameFeatures

This enum describes the different types of features a frame can have.

常量	值	描述
QStyleOptionFrame::None	0x00	Indicates a normal frame.
QStyleOptionFrame::Flat	0x01	Indicates a flat frame.
QStyleOptionFrame::Rounded	0x02	Indicates a rounded frame.

The FrameFeatures type is a typedef for QFlags <FrameFeature>. It stores an OR combination of FrameFeature values.

enum QStyleOptionFrame:: StyleOptionType

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

常量	值	描述
QStyleOptionFrame::Type	SO_Frame	提供样式选项的类型 ( SO_Frame 对于此类)。

类型内部使用通过 QStyleOption ，其子类，和 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 QStyleOptionFrame:: StyleOptionVersion

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

常量	值	描述
QStyleOptionFrame::Version	3	3

版本的使用通过 QStyleOption 子类以实现扩展在不破坏兼容性的情况下。若使用 qstyleoption_cast ()，通常不需要校验它。
