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
handler MyHandler type RUIhandler {initialUI = [ myGridLayout ]} myGridLayout GridLayout{ rows = 4, columns = 3, 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" }; end
