2.1 GWT açıklandı 2010 Google IO yeni yer alacak Data Presentation Widgets. 2.1 M indirmek için kullanılabilir, ve muhtemelen widget dahil, ama hiçbir belge henüz ortaya çıkmamış.

Bunları kullanmak için nasıl kısa bir öğretici veya örnek var mı? CellList CellTable soru sınıfları hakkında bir söylenti gördüm. Onlar için Javadoc TODOs dolu dolu, biraz hala kullanımı açısından eksik.

Google I/O 2010 - GWT's UI overhaul

javadocs package com.google.gwt.cell.client in 2.1

Eclipse update site for milestone 2

Kodu bikeshed ederken, gwt.xml dosyanıza bu satırı ekleyin:

<inherits name='com.google.gwt.requestfactory.RequestFactory'/>

Aşağıdaki örnekleri takip:

• TextCells bu CellList ile PageSizePager
• Bir ile TextCells bu CellList SimplePager
• Bir ile TextCells bu CellList SimplePager ve PageSizePager(buggy) ve
• Dize başlığı ile CellTable ve TextCell başlık
