SWT Jface formlayout 完美布局

  

其实刚刚学习SWT/Jface 不久，之前对AWT有所了解，所以很容易上手。

刚开始我要做一个界面设计，需要用布局完成界面框架，然而这个SWT的布局让我迷惑不已，

我基本上把其中的所有的layout用完了，Filllayout、GridLayout、甚至连sashform都用上了各种组合，

搞得页面那个不堪不已啊，自己都无法忍受，最后实在没办法了而且也就剩下formlayout没有尝试过了。

因为在学习的时候我真的没有发现formlayout 有什么用处、有什么特色，真是失算... 后来仔细研究了一把结果恍然大悟，其实那么多布局，两个就够了，

Filllayout和formlayout。 两个的共同特点就是可以自适应屏，formlayout 就是他提供一中类似于html中百分比一样的东东，

而filllayout呢他提是提供填满效果，两者互不。基本上可以解决大多数情况。

下面给出代码：

package export;

import org.eclipse.swt.SWT;

public class TestFormLayout extends Shell {

	/**
	 * Launch the application.
	 * @param args
	 */
	public static void main(String args[]) {
		try {
			Display display = Display.getDefault();
			TestFormLayout shell = new TestFormLayout(display);
			shell.open();
			shell.layout();
			while (!shell.isDisposed()) {
				if (!display.readAndDispatch()) {
					display.sleep();
				}
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
