public DeselectAllCommand(Editor editor)

Method Detail

execute

public void execute()

remove all selected objects from the editor's Selection collection, and graphically deselect all visible toplevel editor FIG objects.

Unlike other commands, the DeselectAllCommand is not registered with the undo stack, as all previous selection status is lost anyway and cannot be restored.

Overrides:

execute in class Command

undo

public void undo()

undo: do nothing. Because any previous selection status has been lost, there is no way to restore any previous selections. We just print a warning message to that effect.

Overrides:
