Detailed Description

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.

Member Function Documentation

Q3EditorFactory::Q3EditorFactory ( QObject * parent = 0 )

Constructs an editor factory with parent parent.

Q3EditorFactory::~Q3EditorFactory ()

Destroys the object and frees any allocated resources.

QWidget * Q3EditorFactory::createEditor ( QWidget * parent, const QVariant & v ) [virtual]

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.

Q3EditorFactory * Q3EditorFactory::defaultFactory () [static]

Returns an instance of a default editor factory.

void Q3EditorFactory::installDefaultFactory ( Q3EditorFactory * factory ) [static]

Replaces the default editor factory with factory. Q3EditorFactory takes ownership of factory, and destroys it when it is no longer needed.
