Adding New Properties

Adding New Properties

Each section in the map, and each check box, and each row in the bottom table, are populated by properties from a TimeZoneWrapper object. We will change TimeZoneWrapper.java to add the new properties that timezone.xhtml uses JSF expression language bindings to access:

1. Add new property to hold the relative file path to the map image for the time zone being represented by this TimeZoneWrapper:
private String imagePath;
 
2. Add another property for managing both the current state of the check box for this time zone, and the visibility of the corresponding row in the bottom table:
private boolean currentlyShowing;
 
3. Initialize the new properties:
/**
 
 * @param id id used to identify the time zone.
 
 * @param imgPath Path to the image to represent this time zone.
 
 * @param mapId map button component id in web page
 
 * @param checkId checkbox component id in web page
 
 */
 
public TimeZoneWrapper(String id, String imgPath, String mapId, String checkId)
 
{
 
		this.id = id;
 
		this.imagePath = imgPath;
 
		this.mapCommandButtonId = mapId;
 
		this.checkboxId = checkId;
 
		this.currentlyShowing = false;
 
		this.dateFormat = TimeZoneBean.buildDateFormatForTimeZone(
 
				TimeZone.getTimeZone(id) );
 
}
 

 
4. Add accessor methods for the new properties:
public String getImagePath() {
 
		return imagePath;
 
}
 
...
 
public boolean getCurrentlyShowing() {
 
		return currentlyShowing;
 
}
 
...
 
public void setCurrentlyShowing(boolean showing) {
 
		currentlyShowing = showing;
 
}
