The next sections outline a way to develop a Rich UI application. The IDE helps you to do the tasks quickly.

For background information, see Web technology for EGL Rich UI.

Create a Handler type of stereotype RUIHandler

package client;
 
import org.eclipse.edt.rui.widgets.GridLayout;
 
handler MyHandler type RUIhandler{
   initialUI =[ui], 
   onConstructionFunction = start, 
   cssFile = "css/MyProject.css", 
   title = "MyHandler"}
 
   ui GridLayout{columns = 3, rows = 4, cellPadding = 4, children =[]};
 
   function start()
   end
end

An IDE wizard initially creates a grid layout of 3 columns and 4 rows.

Declare, customize, and display widgets

end

Assign and code event handlers

 

Write initialization code in the on-construction function
