NAME

       RotateTool - tool for rotating components

SYNOPSIS

       #include <Unidraw/Tools/rotate.h>

DESCRIPTION

       RotateTool lets the user rotate components by direct manipulation.

PUBLIC OPERATIONS

       RotateTool(ControlInfo* = nil)
              Create a new RotateTool.

       virtual Manipulator* CreateManipulator(
          Viewer*, Event&, Transformer*
       )

       virtual void InterpretManipulator(Manipulator*)
              CreateManipulator detects whether the user clicked on a component.  If not, it clears the editor's
              selection  and  returns  a  nil manipulator.  If a component was hit, and if the component was not
              previously selected, then CreateManipulator clears the editor's selection, selects  the  component
              the  user  hit, and delegates manipulator creation and interpretation to it.  If the component was
              the only selected component, it again delegates manipulator creation  and  interpretation  to  the
              component, but the selection is unaltered.  If the user clicks on one of many selected components,
              then  CreateManipulator will delegate manipulator creation and interpretation to the hit component
              without altering the selection.
