Constructor & Destructor Documentation

◆ QgsPointCloudRendererMetadata()

QgsPointCloudRendererMetadata::QgsPointCloudRendererMetadata	(	const QString &	name,
		const QString &	visibleName,
		QgsPointCloudRendererCreateFunc	pfCreate,
		const QIcon &	icon = `QIcon()`,
		QgsPointCloudRendererWidgetFunc	pfWidget = `nullptr`

Member Function Documentation

◆ createFunction()

inline

Note: not available in Python bindings

Definition at line 153 of file qgspointcloudrendererregistry.h.

◆ createRenderer()

QgsPointCloudRenderer * QgsPointCloudRendererMetadata::createRenderer	(	QDomElement &	elem,
		const QgsReadWriteContext &	context
	)

inlineoverridevirtual

Returns new instance of the renderer given the DOM element.

Returns nullptr on error. Pure virtual function: must be implemented in derived classes.

Implements QgsPointCloudRendererAbstractMetadata.

Definition at line 144 of file qgspointcloudrendererregistry.h.

◆ createRendererWidget()

QgsPointCloudRendererWidget * QgsPointCloudRendererMetadata::createRendererWidget	(	QgsPointCloudLayer *	layer,
		QgsStyle *	style,
		QgsPointCloudRenderer *	oldRenderer
	)

inlineoverridevirtual

Returns new instance of settings widget for the renderer.

Returns nullptr on error.

The oldRenderer argument may refer to previously used renderer (or it is nullptr). If not nullptr, it may be used to initialize GUI of the widget from the previous settings. The old renderer does not have to be of the same type as returned by createRenderer().
