Member Function Documentation

§ configWidget()

QgsEditorConfigWidget * QgsEnumerationWidgetFactory::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 33 of file qgsenumerationwidgetfactory.cpp.

§ create()

QgsEditorWidgetWrapper * QgsEnumerationWidgetFactory::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 28 of file qgsenumerationwidgetfactory.cpp.

§ fieldScore()

unsigned int QgsEnumerationWidgetFactory::fieldScore ( const QgsVectorLayer vl,
int  fieldIdx 
) const
overridevirtual

This method allows disabling this editor widget type for a certain field.

By default, it returns 5 for every fields. Reimplement this if you only support certain fields.

Typical return values are:

  • 0: not supported
  • 5: maybe support (for example, Datetime support strings depending on their content)
  • 10: basic support (this is what returns TextEdit for example, since it supports everything in a crude way)
  • 20: specialised support
Parameters
vl
fieldIdx
Returns
0 if the field is not supported or a bigger number if it can (the widget with the biggest number will be taken by default). The default implementation returns 5..

Reimplemented from QgsEditorWidgetFactory.
