Adding a Talent Display Group
The browser you just created is going to display a list of Talent objects. Like a repetition element, a browser has list and item attributes. As the browser moves through its list, the browser sets item to the object at the current index. The Movies application uses a display group to provide the browser with a list of Talent objects, so now you need to create the new display group and a variable to bind to the browser's item attribute.
- Use the Add Variable/Method command to create two new instance variables:
- talentDisplayGroup, whose type is DisplayGroup
- talent, whose type is Talent
- Using the Display Group Options panel, assign talentDisplayGroup's entity to Talent.
- Configure talentDisplayGroup to sort its objects alphabetically (ascending) by lastName.
- Configure it to fetch on load.
You don't need to add set and get methods for the variables.
Remember that to open the Display Group Options panel, simply
double-click the talentDisplayGroup variable in the object browser. The icon initially displayed next to the variable indicates that initialization parameters have not yet been set.
After you configure talentDisplayGroup, the object browser shows a icon next to the variable.
