The Q3EditorFactory class is used to create editor widgets for QVariant data types.
Each editor factory provides the createEditor() function which given a QVariant will create and return a QWidget that can edit that QVariant. For example if you have a QVariant::String type, a QLineEdit would be the default editor returned, whereas a QVariant::Int's default editor would be a QSpinBox.
If you want to create different editors for fields with the same data type, subclass Q3EditorFactory and reimplement the createEditor() function.
Constructs an editor factory with parent parent.
Destroys the object and frees any allocated resources.
Creates and returns the appropriate editor for the QVariant v. If the QVariant is invalid, 0 is returned. The parent is passed to the appropriate editor's constructor.
Returns an instance of a default editor factory.
Replaces the default editor factory with factory. Q3EditorFactory takes ownership of factory, and destroys it when it is no longer needed.
