Remarks
Parameters
A map of options to pass to the method.
- context - IInputModeContext
- The context to retrieve information about the drag from.
- originalLocation - Point
- The value of the coordinate of the location property at the time of initializeDrag.
Called by clients to indicate that the repositioning has just been finished.
Remarks
Parameters
A map of options to pass to the method.
- context - IInputModeContext
- The context to retrieve information about the drag from.
- originalLocation - Point
- The value of the location property at the time of initializeDrag.
- newLocation - Point
- The coordinates in the world coordinate system that the client wants the handle to be at. Depending on the implementation the location may or may not be modified to reflect the new value. This is the same value as delivered in the last invocation of handleMove.
Called by clients to indicate that the element has been dragged and its position should be updated.
