Detailed Description▲
QStyleOptionFrame is used for drawing several built-in Qt widgets, including QFrame, QGroupBox, QLineEdit, and QMenu.
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.
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.

Member Type Documentation▲
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.

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.
