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

-
attemptMove
(self, point: QgsLayoutPoint, useReferencePoint: bool = True, includesFrame: bool = False, page: int = -1)¶ Attempts to move the item to a specified
point
.If
useReferencePoint
is true, this method will respect the item’s reference point, in that the item will be moved so that its current reference point is placed at the specified target point.If
useReferencePoint
is false, the item will be moved so thatpoint
falls at the top-left corner of the item.If
includesFrame
is true, then the position specified bypoint
represents the point at which to place the outside of the item’s frame.If
page
is not left at the default -1 value, then the position specified bypoint
refers to the relative position on the corresponding layoutpage
(where apage
of 0 represents the first page).Note that the final position of the item may not match the specified target position, as data defined item position may override the specified value.

-
attemptResize
(self, size: QgsLayoutSize, includesFrame: bool = False)¶ Attempts to resize the item to a specified target

includesFrame
is true, then the size specified bysize
includes the item’s frame.See also

is true, then the position and size specified byrect
represents the position and size at for the outside of the item’s frame.Note that the final position and size of the item may not match the specified target rect, as data defined item position and size may override the specified value.

()¶
-
readPropertiesFromElement
(self, element: QDomElement, document: QDomDocument, context: QgsReadWriteContext) → bool¶ Sets item state from a DOM element.
- Parameters
element – is the DOM element for the item
document – DOM document
context – read write context
Note that item subclasses should not rely on all other items being present in the layout at the time this method is called. Instead, any connections and links to other items must be made in the finalizeRestoreFromXml() method. E.g. when restoring a scalebar, the connection to the linked map’s signals should be implemented in finalizeRestoreFromXml(), not readPropertiesFromElement().

-
readXml
(self, itemElement: QDomElement, document: QDomDocument, context: QgsReadWriteContext) → bool¶ Sets the item state from a DOM element.
- Parameters
itemElement – is the DOM node corresponding to item (e.g. ‘LayoutItem’ element)
document – DOM document
context – read write context
Note that item subclasses should not rely on all other items being present in the layout at the time this method is called. Instead, any connections and links to other items must be made in the finalizeRestoreFromXml() method. E.g. when restoring a scalebar, the connection to the linked map’s signals should be implemented in finalizeRestoreFromXml(), not readXml().

The bounds are returned in the item’s coordinate system (see Qt’s QGraphicsItem docs for more details about QGraphicsItem coordinate systems). The results differ from Qt’s rect() function, as rect() makes no allowances for the portion of outlines which are drawn outside of the item.
See also
-
redraw
(self)¶ Triggers a redraw (update) of the item.
-
referencePoint
(self) → QgsLayoutItem.ReferencePoint¶ Returns the reference point for positioning of the layout item. This point is also fixed during resizing of the item, and any size changes will be performed so that the position of the reference point within the layout remains unchanged.
