Constructor Detail

DragTransformInteractor2D

protected DragTransformInteractor2D(int iButton)

Details: This constructor sets the button used for dragging with this interactor. The button values used here are the same as used in FigMouseEvent.

Parameters:

iButton - the button value

Method Detail

mouseButtonPressed

public void mouseButtonPressed(FigMouseEvent iEvent)

Begins drag-translating.

Details: This implementation determines if the button pushed is the button used for this transform interaction, and if it is, it records the point where the drag operation began.

Specified by:

mouseButtonPressed in interface FigMouseButtonListener

Parameters:

iEvent - the mouse event

mouseButtonReleased

public void mouseButtonReleased(FigMouseEvent iEvent)

Ends drag-translating.

Details: This implementation determines if the button released is the button used for this transform interaction, and if it is, it ends the drag operation.

Specified by:

mouseButtonReleased in interface FigMouseButtonListener

Parameters:

iEvent - the mouse event

mouseCursorMoved

public void mouseCursorMoved(FigMouseEvent iEvent)

Continues drag-translating.

Details: This implementation determines if this drag transform is currently in progress, and if it is, transforms the view by an amount appropriate for the dragging that took place since the last mouse event.

Specified by:

mouseCursorMoved in interface FigMouseMotionListener

Parameters:

iEvent - the mouse event
