public class Area extends Region
The Area element of the Runtime Designer Component. The Area class summarizes the Section element(s) into an Area, which makes it possible to change the behavior of all sections together. All sections in an Area have the same characteristics, but each Section in an Area can have a different format. Each Area contains a single Section by default. The name of the Section is based on the name of the enclosing Area, i.e. "D" if there is only one Section in the detail Area. If an Area has more than one Section the names are formed by appending letters of the alphabet, e.g. "Da" for the first Section in the detail Area, "Db" for the second, "Dc" for the third and so on.
` The Section with index "0" in an Area is always the default Section and cannot be removed if it is the only section in the Area, because each Area needs at least one Section.
Add sections with the addSection() method and remove sections with the removeSection(int) method. You can access a Section with the index of the Section, using the method getSection(int). You can get the number of sections in an Area with getSectionCount(). You can merge a Section with the Section below with method mergeSectionBelow(int).
This class is part of the RDC.
