Inheritance diagram for ViewProfileDivider:

Signals
void	signalMovedLow (double xSceneOther)
	Signal used when divider is dragged and m_isLowerBoundary is true.

void	signalMovedHigh (double xSceneOther)
	Signal used when divider is dragged and m_isLowerBoundary is false.

Public Member Functions
	ViewProfileDivider (QGraphicsScene &scene, QGraphicsView &view, int sceneWidth, int sceneHeight, int yCenter, bool isLowerBoundary)
	Single constructor.

virtual QVariant	itemChange (GraphicsItemChange change, const QVariant &value)
	Intercept changes so divider movement can be restricted to horizontal direction only.

virtual void	mousePressEvent (QGraphicsSceneMouseEvent *event)
	Save paddle position at start of click-and-drag.

void	setX (double x, double xLow, double xHigh)
	Set the position by specifying the new x coordinate.

Detailed Description

Divider that can be dragged, in a dialog QGraphicsView.

Click on the paddle to drag. There are three parts:

Paddle which is the superclass of this class, since we catch its events so dragging works
Divider which is a vertical line
Shaded area that extends from xAnchor to the divider
