Dragging

A mixin trait for region-like track tools that enables updates during mouse dragging. It adds an internal class Drag that embodies that dragging state (initial and current positions). Dragging is useful for all parameters that can be continuously changed such as region position but also region gain. It does not necessarily mean that regions are moved. In other words, whenever the mouseDragged event causes a meaningful change in the editing state.

Custom data can be added by the sub-class by specifying the type member Initial.

All the sub-class must do is call new Drag and provide the body of method dragToParam.

Type Members

class Drag extends MouseInputAdapter with KeyListener

Objects that represents a (potential) drag.
Objects that represents a (potential) drag. When instantiated, it installs itself on the parent component of firstEvent and automatically removes itself when the mouse is released.
A drag is only formally started once dragStarted returns true. It will then update the drag state by calling repeatedly into dragToParam and dispatching appropriate events.
A drag can be aborted by pressing the Escape key.

Determines if the drag operations should be started or not.
Determines if the drag operations should be started or not. The default behavior is to wait until the mouse is dragged by around four pixels. Sub-classes may override this, for example to have the drag start immediately without threshold.
returns
true if the parameter data signalize that a drag has started, false if it is not (yet) sufficient.
