NAME¶
ScaleTool - tool for rotating components
SYNOPSIS¶
#include <Unidraw/Tools/scale.h>
DESCRIPTION¶
ScaleTool lets the user rotate components by direct manipulation.
PUBLIC OPERATIONS¶
- ScaleTool(ControlInfo* = nil)
- Create a new ScaleTool.
- 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.
