Function Documentation

QVariant GammaRay::VariantHandler::decoration

(

const QVariant &

value

)

Returns a value representing value in a itemview decoration role.

Parameters

value

is a QVariant.

Returns

a QVariant itemview decoration role.

QString GammaRay::VariantHandler::displayString

(

const QVariant &

value

)

Returns a human readable string version of the QVariant value. Converts to the variant type and prints the string value accordingly.

Parameters

value

is a QVariant.

Returns

a QString containing the human readable string.

template<typename T >

QString GammaRay::VariantHandler::displayString ( T  value )

inline

Returns a human readable string version of the given value. Thihs is a convenience overload of the QVariant-based version above.

Returns

a QString containing the human readable string.

void GammaRay::VariantHandler::registerGenericStringConverter

(

GenericStringConverter

converter

)

Register a generic string conversion function for various variant types. This can be used when you have a converter that can dynamically check if it can handle a given variant, and the types it can handle aren't known at compile time (example: QQmlListProperty).

Parameters

converter

The converter function. It's second parameter is used to indicate if the value could be handled.

void GammaRay::VariantHandler::registerStringConverter	(	int	type,
		Converter< QString > *	converter
	)

Register a string conversion functions for a variant type.

template<typename T , typename FuncT >

void GammaRay::VariantHandler::registerStringConverter ( FuncT  f )

inline

Register a string conversion function for a variant type.

Template Parameters

T	The type for which to use this converter function.
