QItemEditorCreatorBase

The QItemEditorCreatorBase class provides an abstract base class that must be subclassed when implementing new item editor creators. More…

Detailed Description

QItemEditorCreatorBase objects are specialized widget factories that provide editor widgets for one particular QVariant data type. They are used by QItemEditorFactory to create editors for QStyledItemDelegate s. Creator bases must be registered with registerEditor() .

An editor should provide a user property for the data it edits. QItemDelagates can then access the property using Qt’s meta-object system to set and retrieve the editing data. A property is set as the user property with the USER keyword:

Q_PROPERTY(QColor color READ color WRITE setColor USER true)

If the editor does not provide a user property, it must return the name of the property from ; delegates will then use the name to access the property. If a user property exists, item delegates will not call .

QStandardItemEditorCreator is a convenience template class that can be used to register widgets without the need to subclass QItemEditorCreatorBase .
