Setting Up Sketchpad and Cabri II as Helper Applications

You can set up most Web browsers to use helper applications so that when the browser can't open a document itself, it will send it to a helper application. This happens with sounds, pictures, and movies, but you can also set up a browser to use Sketchpad and Cabri to open sketches, scripts, figures, and macros.

Each Web browser uses a different process for defining helper applications, but they all need the same information. Below is the specific information for Sketchpad and Cabri.

Geometer's Sketchpad Settings

You can set up your browser to recognize both sketches and scripts, but you will need to set them up differently since they have different file types.

                Mime type       SubType     Extension     File Code

(for sketches)  application     x-gsp       gsp           GSPk
(for scripts)   application     x-gss       gss           GSPc

You will probably want the action to be "launch application" as well.

Cabri Geometry II Settings

You can set up your browser to recognize both figures and macros, but you will need to set them up differently since they have different file types.

                Mime type       SubType         Extension     File Code

(for figures)   application     x-cabri           fig           FIGU
(for macros)    application     x-cabri-macro     mac           MACR

You will probably want the action to be "launch application" as well.
