- param parentElement:
- addItem(self, item: QgsLayoutItem)¶
Adds an
item
to the group. Ownership of the item is transferred to the group.- Parameters:

- adjustPointForReferencePosition(self, point: QPointF | QPoint, size: QSizeF, reference: QgsLayoutItem.ReferencePoint) QPointF ¶
Adjusts the specified
point
at which areference
position of the item sits and returns the top left corner of the item, if reference point were placed at the specified position.
- applyDataDefinedSize(self, size: QgsLayoutSize) QgsLayoutSize ¶
Applies any present data defined size overrides to the specified layout
size
.
- applyItemSizeConstraint(self, targetSize: QSizeF) QSizeF ¶
Applies any item-specific size constraint handling to a given
targetSize
in layout units. Subclasses can override this method if they need to apply advanced logic regarding item sizes, which cannot be covered bysetFixedSize()
orsetMinimumSize()
. Item size constraints are applied after fixed, minimum and data defined size constraints.See also
