Using the Show or Hide RTF Object Knowledge Object

The Show or Hide RTF Object Knowledge Object shows or hides an existing RTF object that has been previously created using the Create RTF Object Knowledge Object. Basically this does the same thing as the Show RTF Object option in the Create RTF Object Knowledge Object (see the procedure under Creating an RTF Object Knowledge Object). The difference is when the object is made visible or invisible.

The Show RTF Object option in the Create RTF Object Knowledge Object allows you to make the RTF Object visible or invisible at creation time. The Show or Hide RTF Object Knowledge Object allows you to make the RTF Object visible or invisible during the execution of the piece, for example, at runtime when a specific condition is met.

You might want to start off with an invisible object and then make it visible later when it is actually needed. Alternately, you might want to start off with a visible object and later hide it. See Creating an RTF Object Knowledge Object.

To show or hide an existing RTF object:

  1. Drag the Show or Hide RTF Object icon from the Knowledge Objects window to the flowline.

    If you have not previously saved your Authorware file, you are prompted to save it.

    The Show or Hide RTF Object: Introduction screen is displayed.

  2. Click Next, or click ID to display the Show or Hide RTF Object: ID screen.
  3. Enter the variable name of the RTF object you want to show or hide. This variable must have been created using the Create RTF Object Knowledge Object.
  4. Click Next, or click Show or Hide to display the Show or Hide RTF Object: Show or Hide screen.
  5. Select Show RTF Object or Hide RTF Object.
  6. Click Next, or click Finish to display the Show or Hide RTF Object: Finish screen.
  7. When you are ready to implement your choices, click Done.

    When you run your piece, the Show or Hide RTF Object Knowledge Object makes your RTF object visible or invisible, according to the option you selected.

    You must distribute RTFObj.u32 with your piece. The Show or Hide RTF Object Knowledge Object copies this file to the same location as your piece.

    Note: If you need to change any of the settings, double-click the Show or Hide RTF Object icon on the flowline to run the Knowledge Object again.
