Member Function Documentation

◆ createWidget()

virtual QWidget* QgsLayerTreeEmbeddedWidgetProvider::createWidget ( QgsMapLayer layer,
int  widgetIndex 
)
pure virtual

Factory to create widgets.

The returned widget is owned by the caller. The widgetIndex argument may be used to identify which widget is being created (useful when using multiple widgets from the same provider for one layer).

◆ id()

virtual QString QgsLayerTreeEmbeddedWidgetProvider::id ( ) const
pure virtual

Unique name of the provider (among other providers)

◆ name()

virtual QString QgsLayerTreeEmbeddedWidgetProvider::name ( ) const
pure virtual

Human readable name - may be translatable with tr()

◆ supportsLayer()

virtual bool QgsLayerTreeEmbeddedWidgetProvider::supportsLayer ( QgsMapLayer layer)
pure virtual

Whether it makes sense to use this widget for a particular layer.
