Creating parts
To add a new part to an application, do the following:
1. From the Applications pane, select the application to contain the part.
2. From the Parts menu, select New.
3. In the displayed
New Part window, type a name for the part in
Part class field. The name must begin with a capital letter and contain no spaces.
4. Select the type of part you want from the Part type drop-down list.
Visual part
Select Visual part for a user interface (or view).
Nonvisual part
Select Nonvisual part for a part that does not have a view, but contains scripts used by your application.
Smalltalk class
Select Smalltalk class to subclass a Smalltalk class such as Object or String.
5. From the Inherits from drop-down list, select the class from which your part will inherit.
Notice that the class names shown in the drop-down list change whenever you select a different part type. For visual and nonvisual parts, you likely want the defaults. For Smalltalk classes, select from the list the Smalltalk class whose attributes and methods are of most use to your part.
If you do not see the class from which the part will inherit in the list, type the name of the superclass in the text pane.
6. To open a VA Smalltalk editor on the new part, keep the check mark beside Open now. To make the part and not work on it immediately, deselect the check box.
7. Select OK.
