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.
