GridLayout網格布局時最常用的布局之一，類似于Html中使用table布局。通過使用GridData來設置布局參數。

做個例子看看。

代碼：

import?org.eclipse.swt.SWT;

import?org.eclipse.swt.layout.FillLayout;

import?org.eclipse.swt.layout.GridData;

import?org.eclipse.swt.layout.GridLayout;

import?org.eclipse.swt.widgets.Button;

import?org.eclipse.swt.widgets.Composite;

import?org.eclipse.swt.widgets.Display;

import?org.eclipse.swt.widgets.Group;

import?org.eclipse.swt.widgets.Label;

import?org.eclipse.swt.widgets.List;

import?org.eclipse.swt.widgets.Shell;

import?org.eclipse.swt.widgets.Text;
