A Properties view provides a way to display and set the attributes and other options associated with a part or connection. In addition to part-specific properties, you can set data validation, layout, drag and drop, and help information. For example, you can add an OK push button and define it as the default push button by opening the properties view for the Push Button part and setting the value of the showAsDefault property to true. A part's properties view is displayed using the Properties window for a part.
