The QStyleHintReturn class provides style hints that return more than basic data types.
QStyleHintReturn and its subclasses are used to pass information from a style back to the querying widget. This is most useful when the return value from QStyle::styleHint() does not provide enough detail; for example, when a mask is to be returned.
Constant | Value | Description |
---|---|---|
QStyleHintReturn::SH_Default | 0xf000 | QStyleHintReturn |
QStyleHintReturn::SH_Mask | QStyle::SH_RubberBand_Mask QStyle::SH_FocusFrame_Mask |
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.
Equals SH_Default.
Equals 1.
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. It behaves essentially like the above function.
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. It behaves essentially like the above function.
Returns a T or 0 depending on the type of hint.
