Member Function Documentation

◆ changed

void QgsSymbolLayerWidget::changed ( )

signal

Should be emitted whenever configuration changes happened on this symbol layer configuration.

If the subsymbol is changed, symbolChanged() should be emitted instead.

◆ context()

QgsSymbolWidgetContext QgsSymbolLayerWidget::context ( ) const

Returns the context in which the symbol widget is shown, e.g., the associated map canvas and expression contexts.

See also: setContext()

Definition at line 135 of file qgssymbollayerwidget.cpp.

◆ createExpressionContext()

QgsExpressionContext QgsSymbolLayerWidget::createExpressionContext ( ) const

overrideprotectedvirtual

This method needs to be reimplemented in all classes which implement this interface and return an expression context.

Implements QgsExpressionContextGenerator.

Definition at line 66 of file qgssymbollayerwidget.cpp.

◆ registerDataDefinedButton()

void QgsSymbolLayerWidget::registerDataDefinedButton	(	QgsPropertyOverrideButton *	button,
		QgsSymbolLayer::Property	key
	)

protected

Registers a data defined override button.

Handles setting up connections for the button and initializing the button to show the correct descriptions and help text for the associated property.

Definition at line 140 of file qgssymbollayerwidget.cpp.

◆ setContext()

void QgsSymbolLayerWidget::setContext ( const QgsSymbolWidgetContext & context )

virtual

Sets the context in which the symbol widget is shown, e.g., the associated map canvas and expression contexts.

Parameters

context symbol widget context

Reimplemented in QgsSimpleLineSymbolLayerWidget, QgsMarkerLineSymbolLayerWidget, QgsHashedLineSymbolLayerWidget, QgsSvgMarkerSymbolLayerWidget, QgsRasterMarkerSymbolLayerWidget, QgsAnimatedMarkerSymbolLayerWidget, QgsSVGFillSymbolLayerWidget, and QgsLinearReferencingSymbolLayerWidget.

Definition at line 125 of file qgssymbollayerwidget.cpp.

◆ setSymbolLayer()

virtual void QgsSymbolLayerWidget::setSymbolLayer ( QgsSymbolLayer * layer )

pure virtual

◆ symbolChanged

void QgsSymbolLayerWidget::symbolChanged ( )

signal

Should be emitted whenever the sub symbol changed on this symbol layer configuration.

Normally changed() should be preferred.

◆ symbolLayer()

virtual QgsSymbolLayer * QgsSymbolLayerWidget::symbolLayer ( )

pure virtual

◆ updateDataDefinedProperty

void QgsSymbolLayerWidget::updateDataDefinedProperty ( )

protectedslot

Definition at line 189 of file qgssymbollayerwidget.cpp.

◆ vectorLayer()

const QgsVectorLayer * QgsSymbolLayerWidget::vectorLayer ( ) const

inline

Returns the vector layer associated with the widget.
