Features of SamplePart(OD Cookbook)

Inside Macintosh: OpenDoc Cookbook /: Chapter 2 - SamplePart Tutorial

Features of SamplePart
SamplePart implements a complete but minimum set of features. Although it's possible to write an executable part editor with even fewer features, it would not be very useful.
From the user's point of view, SamplePart's primary capability is simply to display a text string. It can also display itself in small icon, large icon, and thumbnail views. SamplePart also supports the Save command and, when embedded in a container part, the View as Window command.
In order to support its feature set and interact properly with other parts, SamplePart performs the following tasks, which are described in this chapter:

initialization
opening the part into a window
handling frame layout
drawing the part's content
handling basic events
activation
writing the part to persistent storage

In addition, this chapter shows how to set up your part editor's resources so that OpenDoc can match it with its parts.
