Q3EditorFactory Class Reference
[Qt3Support module]

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.
