Detailed Description

Stores metadata about one point cloud renderer class.

Note: It's necessary to implement createRenderer() function. In C++ you can use QgsPointCloudRendererMetadata convenience class.

Since: QGIS 3.18

Constructor & Destructor Documentation

◆ QgsPointCloudRendererAbstractMetadata()

QgsPointCloudRendererAbstractMetadata::QgsPointCloudRendererAbstractMetadata	(	const QString &	name,
		const QString &	visibleName,
		const QIcon &	icon = `QIcon()`
	)

inline

Constructor for QgsPointCloudRendererAbstractMetadata, with the specified name.

The visibleName argument gives a translated, user friendly string identifying the renderer type.

The icon argument can be used to specify an icon representing the renderer.

Member Function Documentation

◆ createRenderer()

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

pure virtual

Returns new instance of the renderer given the DOM element.

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

Implemented in QgsPointCloudRendererMetadata.

◆ createRendererWidget()

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

inlinevirtual

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().
