Constructor & Destructor Documentation

◆ Qgs3DAlgorithms()

Qgs3DAlgorithms::Qgs3DAlgorithms ( QObject * parent = nullptr )

Constructor for Qgs3DAlgorithms.

Member Function Documentation

◆ helpId()

QString Qgs3DAlgorithms::helpId ( ) const

overridevirtual

Returns the provider help id string, used for creating QgsHelp urls for algorithms belong to this provider.

By default, this returns an empty string, meaning that no QgsHelp url should be created for the provider's algorithms.

See also: id()

Reimplemented from QgsProcessingProvider.

◆ icon()

QIcon Qgs3DAlgorithms::icon ( ) const

overridevirtual

Returns an icon for the provider.

See also: svgIconPath()

Reimplemented from QgsProcessingProvider.

◆ id()

QString Qgs3DAlgorithms::id ( ) const

overridevirtual

Returns the unique provider id, used for identifying the provider.

This string should be a unique, short, character only string, eg "qgis" or "gdal". This string should not be localised.

See also: name(); helpId()

Implements QgsProcessingProvider.

◆ loadAlgorithms()

void Qgs3DAlgorithms::loadAlgorithms ( )

overrideprotectedvirtual

Loads all algorithms belonging to this provider.

Subclasses should implement this, calling addAlgorithm() to register all their associated algorithms.

Implements QgsProcessingProvider.

◆ name()

QString Qgs3DAlgorithms::name ( ) const

overridevirtual

Returns the provider name, which is used to describe the provider within the GUI.

This string should be short (e.g. "Lastools") and localised.

See also: longName(); id()

Implements QgsProcessingProvider.

◆ supportsNonFileBasedOutput()

bool Qgs3DAlgorithms::supportsNonFileBasedOutput ( ) const

overridevirtual

Returns true if the provider supports non-file based outputs (such as memory layers or direct database outputs).

If a provider returns false for this method than it indicates that none of the outputs from any of the provider's algorithms have support for non-file based outputs. Returning true indicates that the algorithm's parameters will each individually declare their non-file based support.

The default behavior for providers is to support non-file based outputs, and most providers which rely solely on QGIS API (and which do not depend on third-party scripts or external dependencies) will automatically support this.

See also: supportedOutputVectorLayerExtensions()

Reimplemented from QgsProcessingProvider.

◆ svgIconPath()

QString Qgs3DAlgorithms::svgIconPath ( ) const

overridevirtual

Returns a path to an SVG version of the provider's icon.

See also: icon()

Reimplemented from QgsProcessingProvider.
