Creating a subclass

To subclass from Object, do the following:

  1. From a standard Application Browser opened on DevelopChooser, select Object.
  2. From the Classes menu, select Add > Subclass.
  3. In the displayed prompter, type Chooser, then select OK. A window opens, prompting you to select what type of subclass should be added.

    The choices are:

    subclass
    Add a class that has only named instance variables.

    variableSubclass
    Add a class that has indexed instance variables capable of storing arbitrary objects, and can also have named instance variables.

    variableByteSubclass
    Add a class that has indexed instance variables that hold bytes.

    variableWordSubclass
    Add a class that has indexed instance variables that hold words.

    variableLongSubclass
    Add a class that has indexed instance variables that hold long words.
  4. Select subclass; then select OK.
    Subclass

You have just created a new class in DevelopChooser. In an Application Browser, you can now view the class definition of class Chooser. In an Application Manager with DevelopChooser selected, you can see that a new class edition named Chooser is listed in the classes pane.
