class qgis.gui.QgsLayoutViewMouseEvent(view: QgsLayoutView, event: QMouseEvent, snap: bool = False)

Bases: PyQt5.QtGui.QMouseEvent

Constructor for QgsLayoutViewMouseEvent. Should only be required to be called from the QgsLayoutView.

Parameters:
  • view – The view in which the event occurred.
  • event – The original mouse event
  • snap – set to true to snap the point using the layout’s snapping settings

QgsLayoutViewMouseEvent(QgsLayoutViewMouseEvent)

A QgsLayoutViewMouseEvent is the result of a user interaction with the mouse on a QgsLayoutView.

It is sent whenever the user moves, clicks, releases or double clicks the mouse. In addition to the coordinates in pixel space it also knows the coordinates the layout space.

New in version 3.0: Methods

isSnapped Returns true if point was snapped, e.g.
layoutPoint Returns the event point location in layout coordinates.
snapPoint Manually triggers a snap for the mouse event position using the layout’s snapper.
snappedPoint Returns the snapped event point location in layout coordinates.

Attributes

isSnapped(self) → bool

Returns true if point was snapped, e.g. to grid or guide lines.

snappedPoint()

layoutPoint(self) → QPointF

Returns the event point location in layout coordinates.

snapPoint(self, horizontalSnapLine: QGraphicsLineItem = None, verticalSnapLine: QGraphicsLineItem = None, ignoreItems: Iterable[QgsLayoutItem] = [])

Manually triggers a snap for the mouse event position using the layout’s snapper.

If the horizontalSnapLine and verticalSnapLine arguments are specified, then the snapper will automatically display and position these lines to indicate snapping positions to item bounds.

The ignoreItems argument can be used to specify a list of items to avoid snapping to.

snappedPoint(self) → QPointF

Returns the snapped event point location in layout coordinates. The snapped point will consider all possible snapping methods, such as snapping to grid or guide lines.
