Public Functions¶

Type	Name
	PointerTracker (QObject * parent=nullptr) Constructs a tracker owned by parent .
void	hoverEnter (const QHoverEvent & event) Places the pointer where the hover enters, unless a touch is in progress.
void	hoverLeave () Removes the pointer when the mouse leaves; a touch pointer stays.
void	hoverMove (const QHoverEvent & event) Places the pointer at a hover move, which always comes from the mouse.
void	mouseMove (const QMouseEvent & event) Places the pointer at a move, except the button-less move Qt Quick sends after a touch release.
std::optional< QPointF >	position () const Returns the pointer position in plot-local logical pixels, or nothing while no pointer is over the plot.
void	press (const QMouseEvent & event) Places the pointer at a mouse or touch press.
void	release () Ends a press, on release or when the plot loses its grab.

Detailed Description¶

A touch places the pointer where the finger is and leaves it there after the release, until the next tap or mouse movement.
