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, and QMenu.
An instance of the QStyleOptionFrame class has type SO_Frame and version 3.
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 do not need to check it.
For an example demonstrating how style options can be used, see the Styles example.
参见 QStyleOption.
成员类型
enum QStyleOptionFrame::FrameFeature
flags QStyleOptionFrame::FrameFeatures
This enum describes the different types of features a frame can have.
| Constant | Value | Description |
|---|---|---|
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 subclass.
| Constant | Value | Description |
|---|---|---|
QStyleOptionFrame::Type | SO_Frame | The type of style option provided (SO_Frame 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 QStyleOptionFrame::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 |
|---|---|---|
QStyleOptionFrame::Version | 3 | 3 |
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.
成员函数
QStyleOptionFrame::QStyleOptionFrame()
Constructs a QStyleOptionFrame, initializing the members variables to their default values.
QStyleOptionFrame::QStyleOptionFrame(const QStyleOptionFrame &other)
Constructs a copy of the other style option.
成员变量
FrameFeatures QStyleOptionFrame::features
This variable holds a bitwise OR of the features that describe this frame.
参见 FrameFeature.
QFrame::Shape QStyleOptionFrame::frameShape
This property holds the frame shape value of the frame.
int QStyleOptionFrame::lineWidth
This variable holds the line width for drawing the frame
The default value is 0.
int QStyleOptionFrame::midLineWidth
This variable holds the mid-line width for drawing the frame
This is usually used in drawing sunken or raised frames.
The default value is 0.
