Constructor for
QgsLayoutItemGroup
, belonging to the specifiedlayout
.A container for grouping several QgsLayoutItems.
New in version 3.0.
- Parameters

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

adjustPointForReferencePosition
(self, point: Union[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
