Detailed Description

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.

Since: QGIS 3.0

Constructor & Destructor Documentation

◆ QgsLayoutViewMouseEvent()

QgsLayoutViewMouseEvent::QgsLayoutViewMouseEvent	(	QgsLayoutView *	view,
		QMouseEvent *	event,
		bool	snap = `false`
	)

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

Definition at line 21 of file qgslayoutviewmouseevent.cpp.

Member Function Documentation

◆ isSnapped()

bool QgsLayoutViewMouseEvent::isSnapped ( ) const

inline

Returns true if point was snapped, e.g.

to grid or guide lines.

See also: snappedPoint()

Definition at line 84 of file qgslayoutviewmouseevent.h.

◆ layoutPoint()

QPointF QgsLayoutViewMouseEvent::layoutPoint ( ) const

Returns the event point location in layout coordinates.

Definition at line 44 of file qgslayoutviewmouseevent.cpp.

◆ snappedPoint()

QPointF QgsLayoutViewMouseEvent::snappedPoint ( ) const

inline

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.

See also: isSnapped()

Definition at line 78 of file qgslayoutviewmouseevent.h.

◆ snapPoint()

void QgsLayoutViewMouseEvent::snapPoint	(	QGraphicsLineItem *	horizontalSnapLine = `nullptr`,
		QGraphicsLineItem *	verticalSnapLine = `nullptr`,
		const QList< QgsLayoutItem *> &	ignoreItems = `QList< 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.
