Class: QgsProcessingParameterTinInputLayers

class qgis.core.QgsProcessingParameterTinInputLayers

Bases: QgsProcessingParameterDefinition

A parameter for processing algorithms that need a list of input vector layers to construct a TIN.

A valid value for this parameter is a list (QVariantList), where each item is a map (QVariantMap) in this form: { ‘source’: string that represents identification of the vector layer, ‘type’: how the vector layer is used : as vertices, structure lines or break lines ‘attributeIndex’ : the index of the attribute of the vector layer used to defined the Z value of vertices, if -1, the Z coordinates of features are used }

Added in version 3.16.
