It contains state regarding the current state of the operation to enable the operations initiator to provide the end user with the appropriate drag over feedback.

Constructor Detail

DragSourceDragEvent

public DragSourceDragEvent(DragSourceContext dsc,
                           int dropAction,
                           int actions,
                           int modifiers)
Constructs a DragSourceDragEvent. This class is typically instantiated by the DragSourceContextPeer rather than directly by client code.

Parameters:
dsc - the DragSourceContext that is to manage notifications for this event.
dropAction - the value of one of the static fields from DNDConstants indicating the type of user drop action this event represents.
actions - the value of one of the static fields from DNDConstants indicating the type of target drop action supported by and returned from the current drop target.
modifiers - specifies the state of the input device modifiers associated with the user gesture.
Method Detail

getTargetActions

public int getTargetActions()
This method returns the logical intersection of the current target, source, and user actions.

Returns:
the logical intersection of the current target, source and user actions

getGestureModifiers

public int getGestureModifiers()
This method returns an int representing the current state of the input device modifiers associated with the user's gesture. Typically these would be mouse buttons or keyboard modifiers.

Returns:
the current state of the input device modifiers

getUserAction

public int getUserAction()
This method returns an int representing the user's currently selected drop action.

Returns:
the user's currently selected drop action

getDropAction

public int getDropAction()
This method returns an int representing the effective drop action which is the intersection of the user's selected action, and the source and target actions.
