Detailed Description

The PySide.QtGui.QItemEditorFactory class provides widgets for editing item data in views and delegates.

When editing data in an item view, editors are created and displayed by a delegate. PySide.QtGui.QItemDelegate , which is the delegate by default installed on Qt’s item views, uses a PySide.QtGui.QItemEditorFactory to create editors for it. A default unique instance provided by PySide.QtGui.QItemEditorFactory is used by all item delegates. If you set a new default factory with PySide.QtGui.QItemEditorFactory.setDefaultFactory() , the new factory will be used by existing and new delegates.

A factory keeps a collection of PySide.QtGui.QItemEditorCreatorBase instances, which are specialized editors that produce editors for one particular PySide.QtCore.QVariant data type (All Qt models store their data in PySide.QtCore.QVariant s).

Standard Editing Widgets

The standard factory implementation provides editors for a variety of data types. These are created whenever a delegate needs to provide an editor for data supplied by a model. The following table shows the relationship between types and the standard editors provided.

Type	Editor Widget
bool	PySide.QtGui.QComboBox
double	PySide.QtGui.QDoubleSpinBox
int	PySide.QtGui.QSpinBox
unsigned int
PySide.QtCore.QDate	PySide.QtGui.QDateEdit
PySide.QtCore.QDateTime	PySide.QtGui.QDateTimeEdit
PySide.QtGui.QPixmap	PySide.QtGui.QLabel
PySide.QtCore.QString	PySide.QtGui.QLineEdit
PySide.QtCore.QTime	PySide.QtGui.QTimeEdit

Additional editors can be registered with the PySide.QtGui.QItemEditorFactory.registerEditor() function.
