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{ // sets one or more widgets at the root of the widget tree. initialUI =[ui], // specifies the function that runs initially and without user interaction. onConstructionFunction = start, // identifies the CSS file that helps you to design the page. cssFile = "css/MyProject.css", // sets the title that is displayed at the top of your browser or browser tab. 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
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 =[myLabel, myTextField, myCheckBox, myButton]}; myLabel TextLabel{ layoutData = new GridLayoutData{ row = 1, column=1}, text = "Label: " }; myTextField TextField{ layoutData = new GridLayoutData{ row = 1, column = 2, horizontalSpan = 2 }, text = "Text field"}; myCheckBox CheckBox{ layoutData = new GridLayoutData{ row = 2, column = 2, verticalSpan = 2 }, text="Check box" }; myButton Button{ layoutData = new GridLayoutData{ row = 4, column = 1, horizontalSpan = 2, horizontalAlignment = GridLayoutLib.Align_Center }, text="Button" }; function start() end end
