Detailed Description

Implementation of legend node interface for displaying WMS legend entries.

Constructor & Destructor Documentation

QgsWMSLegendNode::QgsWMSLegendNode	(	QgsLayerTreeLayer *	nodeLayer,
		QObject *	parent = `0`
	)

QVariant QgsWMSLegendNode::data ( int role ) const

overridevirtual

Return data associated with the item.

Must be implemented in derived class.

QSizeF QgsWMSLegendNode::drawSymbol	(	const QgsLegendSettings &	settings,
		ItemContext *	ctx,
		double	itemHeight
	)		const

overridevirtual

Draws symbol on the left side of the item.

Parameters

settings	Legend layout configuration
ctx	Context for rendering - may be null if only doing layout without actual rendering
itemHeight	Minimal height of the legend item - used for correct positioning when rendering

Returns: Real size of the symbol (may be bigger than "normal" symbol size from settings)

void QgsWMSLegendNode::invalidateMapBasedData ( )

overridevirtual

Notification from model that information from associated map view has changed.

Default implementation does nothing.
