Creating a Rotation Interactor

 INDEX Gray bullet PREVIOUS NEXT

A rotation interactor is used to revolve a symbol object when the mouse hovers over an object in a symbol. The rotation interactor changes the value of the parameter to which it is bound. This change in parameter value is used to make a rotation transformation on the object bound to the parameter. For example, if you rotate the mouse over a dial symbol, the dial knob rotates with the mouse.

To add a rotation interactor to a symbol, do the following:

  1. In the Symbol Editor, create a new symbol. For more information, see Making a New Symbol.
  2. Import the nobvista.svg image from the <installdir>/jviews-diagrammer81/bin/symboleditor/data/examples directory. The SVG image creates an SVG object. For more information, see Importing a Vector Graphic.
  3. Delete the Text and Shape objects. SVG is now the base object.
  4. Ungroup the SVG object.
  5. Create a float parameter rotation. For more information, see Creating a New Parameter.
  6. Select the GeneralPath5 dial knob object.
