Constant | Value | Description |
---|---|---|
QStyleHintReturn::SH_Default | 0xf000 | QStyleHintReturn |

This enum is used to hold information about the type of the style option, and is defined for each QStyleHintReturn subclass.
Constant | Value | Description |
---|---|---|
QStyleHintReturn::Type | SH_Default | The type of style option provided (SH_Default for this class). |
The type is used internally by QStyleHintReturn, 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 QStyleHintReturn subclass and your own styles.
See also StyleOptionVersion.
This enum is used to hold information about the version of the style option, and is defined for each QStyleHintReturn subclass.
Constant | Value | Description |
---|---|---|
QStyleHintReturn::Version | 1 | 1 |
The version is used by QStyleHintReturn subclasses to implement extensions without breaking compatibility. If you use qstyleoption_cast(), you normally don't need to check it.
See also StyleOptionType.
Constructs a QStyleHintReturn with version version and type type.
The version has no special meaning for QStyleHintReturn; it can be used by subclasses to distinguish between different version of the same hint type.
See also QStyleOption::version and QStyleOption::type.
This variable holds the type of the style hint container.
See also HintReturnType.
This variable holds the version of the style hint return container.
This value can be used by subclasses to implement extensions without breaking compatibility. If you use qstyleoption_cast<T>(), you normally don't need to check it.
This is an overloaded member function, provided for convenience.
Returns a T or 0 depending on the type and version of hint.
Example:
int MyStyle::styleHint(StyleHint stylehint, const QStyleOption *opt, const QWidget *widget, QStyleHintReturn* returnData) const; { if (stylehint == SH_RubberBand_Mask) { const QStyleHintReturnMask *maskReturn = qstyleoption_cast<const QStyleHintReturnMask *>(hint); if (maskReturn) { ... } } ... }
See also QStyleHintReturn::type and QStyleHintReturn::version.
This is an overloaded member function, provided for convenience.
Returns a T or 0 depending on the type of hint.
