Although the example illustrated here covers rectangles, this tech tip also applies to ovals and matrices.

To create a transparent rectangle:


  1. While designing a form, make sure the tools palette is visible.
  2. Click on the rectangle tool.
  3. Create a rectangle on the form.
  4. Open the property list.
  5. Make sure the rectangle is selected.
  6. In the property list, Expand the "Appearance" item.
  7. Click on "Fill Pattern".
  8. Select "N".

This is one of the many reasons why we always recommend testing your application and interface on the platform on which it will be used.
