                                                  int dropAction)

Constructs a new command.

Parameters:

node - the hierarchy / tree node on which the timeline object is located

layer - the layer where the timeline object gets displayed

object - the timeline object that will be modified by the command

model - the model from which the timeline object originated

span - the new time span that will be assgined to the timeline object

dropAction - the type of drop performed by the user (possible values are defined in DnDConstants)

Method Detail

executeCommand

public void executeCommand(IProgressMonitor monitor)

Description copied from interface: ICommand

Executes the command.

Parameters:

Returns:

the model to which the timeline object belongs

Since:

1.0

getNewTimeSpan

public ITimeSpan getNewTimeSpan()

Returns the time span that will be / was assigned to the timeline object by the command.

Returns:

the new time span of the timeline object

Returns:

the tree node to which the timeline object belongs

Since:
