Returns camera view.
Contains settings and helpers relating to a render of a QgsLayoutItem.
Definition: qgslayoutitem.h:45
Base class for graphical items within a QgsLayout.
virtual bool writePropertiesToElement(QDomElement &element, QDomDocument &document, const QgsReadWriteContext &context) const
Stores item state within an XML DOM element.
virtual void finalizeRestoreFromXml()
Called after all pending items have been restored from XML.

virtual void draw(QgsLayoutItemRenderContext &context)=0
Draws the item's contents using the specified item render context.
Base class for layouts, which can contain items such as maps, labels, scalebars, etc.
Definition: qgslayout.h:51
The class is used as a container of context for various read/write operations on other objects.
