Drag-Point Interactor
A drag-point interactor allows the user to drag a data point. It has the following basic characteristics:
Class | |
Registered name | “ChartDragPoint” |
Inherits from | |
Key or Button | Left mouse button |
Action | Lets the user modify a data point by dragging its graphical representation within the data display area. |
The mouse button used to perform the drag operation is the left mouse button by default. However, this button can be changed by passing another button as a parameter to the constructor of the drag-point interactor.
You can use two modes for the drag operation:
With the
opaque mode, the data point is modified each time the mouse is dragged.
With the
ghost mode, the data point is modified only when the mouse button is released.
When a drag-point interactor is created, the default mode that is used for the drag operation is the ghost mode. You can specify that the opaque mode should be used by calling the method IlvChartDragPointInteractor::setOpaque with IlvTrue as a parameter.
