Member Function Documentation

configWidget()

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

overridevirtual

Override this in your implementation.

Create a new configuration widget for this widget type.

Parameters

vl	The layer for which the widget will be created
fieldIdx	The field index for which the widget will be created
parent	The parent widget of the created config widget

Returns

A configuration widget

Implements QgsEditorWidgetFactory.

create()

QgsEditorWidgetWrapper * QgsExternalResourceWidgetFactory::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

vl	The vector layer on which this widget will act
fieldIdx	The field index on which this widget will act
editor	An editor widget if already existent. If nullptr is provided, a new widget will be created.
parent	The parent for the wrapper class and any created widget.

Returns

A new widget wrapper

Implements QgsEditorWidgetFactory.

Definition at line 28 of file qgsexternalresourcewidgetfactory.cpp.

fieldScore()

unsigned int QgsExternalResourceWidgetFactory::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: specialized 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..
