Class Hierarchy

Subclasses

QgsAbstractReportSection	An abstract base class for QgsReport subsections.
QgsLayoutAtlas	Class used to render QgsLayout as an atlas, by iterating over the features from an associated vector layer.

Methods

beginRender	Called when rendering begins, before iteration commences.
count	Returns the number of features to iterate over.
endRender	Ends the render, performing any required cleanup tasks.
filePath	Returns the file path for the current feature, based on a specified base file path and extension.
layout	Returns the layout associated with the iterator.
next	Iterates to next feature, returning False if no more features exist to iterate over.
