.SH DESCRIPTION
Acts like a union for the most common Qt data types.
.PP
Unfortunately one can not use C++ unions with classes that have constructors and destructors since the compiler and the runtime library could not determine which destructor to call.
.PP
To come around this QProperty can store the most common Qt and C++ data types. Like every union it can hold one value of a certain type at a time.
.SH MEMBER FUNCTION DOCUMENTATION

.SH "QProperty::QProperty ( double _v )"
Creates a new property with a floating point value.
.SH "QProperty::QProperty ( int _v )"
Creates a new property with an integer value.
.SH "QProperty::~QProperty () \fC[virtual]\fR"
Subclasses which re-implement clear() should reimplement the destructor to call clear() - so that the overridden clear() is called.
.SH "bool QProperty::boolValue () const"
Returns the value stored in the property. If the properties value does not match the return type of this function then this function will abort your process. So check with type() or typeName() first wether the property holds the correct data type.
.SH "const QBrush& QProperty::brushValue () const"
Returns the value stored in the property. If the properties value does not match the return type of this function then this function will abort your process. So check with type() or typeName() first wether the property holds the correct data type.

De-allocate, based on the type, producing an Empty property.
.SH "const QColor& QProperty::colorValue () const"

.SH "int QProperty::intValue () const"
Returns the value stored in the property. If the properties value does not match the return type of this function then this function will abort your process. So check with type() or typeName() first wether the property holds the correct data type.
.SH "bool QProperty::isEmpty () const"
Returns TRUE if the storage type of this property is QProperty::Empty.
.SH "void QProperty::load ( QDataStream & s ) \fC[virtual]\fR"
Internal function for loading a property. Use the stream operators instead.
.SH "QProperty& QProperty::operator= ( const QProperty & p )"
