Member Function Documentation

◆ configWidget()

QgsEditorConfigWidget * QgsUniqueValueWidgetFactory::configWidget ( QgsVectorLayer vl,
int  fieldIdx,
QWidget parent 
) const
overridevirtual

Override this in your implementation.

Create a new configuration widget for this widget type.

Parameters
vlThe layer for which the widget will be created
fieldIdxThe field index for which the widget will be created
parentThe parent widget of the created config widget
Returns
A configuration widget

Implements QgsEditorWidgetFactory.

Definition at line 32 of file qgsuniquevaluewidgetfactory.cpp.

◆ create()

QgsEditorWidgetWrapper * QgsUniqueValueWidgetFactory::create ( QgsVectorLayer vl,
int  fieldIdx,
QWidget editor,
QWidget parent 
) const
overridevirtual

Override this in your implementation.

Create a new editor widget wrapper. Call QgsEditorWidgetRegistry::create() instead of calling this method directly.

Parameters
vlThe vector layer on which this widget will act
fieldIdxThe field index on which this widget will act
editorAn editor widget if already existent. If NULL is provided, a new widget will be created.
parentThe parent for the wrapper class and any created widget.
Returns
A new widget wrapper

Implements QgsEditorWidgetFactory.

Definition at line 27 of file qgsuniquevaluewidgetfactory.cpp.

◆ readConfig()

QgsVectorLayer layer,
int  fieldIdx 
)

Read the config from an XML file and map it to a proper QgsEditorWidgetConfig.

Parameters
configElementThe configuration element from the project file
layerThe layer for which this configuration applies
fieldIdxThe field on the layer for which this configuration applies
Returns
A configuration object. This will be passed to your widget wrapper later on

Reimplemented from QgsEditorWidgetFactory.

Definition at line 37 of file qgsuniquevaluewidgetfactory.cpp.

◆ writeConfig()
