Adding the MovieDetails Page

8. In Project Builder, modify the showDetails action to look like the

following:

public Component showDetails()

{

MovieDetails nextPage =

(MovieDetails)application().pageWithName("MovieDetails");

EnterpriseObject selection =

(EnterpriseObject)movieDisplayGroup.selectedObject();

nextPage.setSelectedMovie(selection);

return nextPage;

}

This method creates the MovieDetails page and then invokes its

setSelectedMovie method with the movie that’s selected in the Main page.

The display group method

selectedObject returns its selected object,

which, in the Main component, is set when a user clicks a movie title

hyperlink.

Designing MovieDetails’ User Interface

Now lay out the user interface for MovieDetails. When you’re done, your

component should look like the following:

1. Create a top-level heading with the text

Movie Details.

Recall that to create a top-level heading, you type the text of the

heading, select the text, click the button to add a heading element

around the text, and then use the Inspector to set the heading’s level,

as you did in “Using the Inspector” (page 22).

2. Below the heading, add a string element.

3. With the string element selected, add a heading.
