swt eclipse文件选择器

最近在写swt程序的时候，发现SWT Designer图形化工具的面板中找不到直接拖动的文件选择器。发现eclipse里面有很多的文件选择器，所以肯定是支持的，只是这个图形化工具不直接支持而已。查了下资料，发现其实很简单，就是在页面上添加一个按钮，然后为这个按钮实现选中事件，在事件中新建类就可以实现。不多说了，直接上代码。

package com.devexception;

import java.io.IOException;

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.widgets.Button;

import org.eclipse.swt.widgets.FileDialog;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;
import org.eclipse.ui.forms.events.HyperlinkAdapter;
import org.eclipse.ui.forms.events.HyperlinkEvent;
import org.eclipse.ui.forms.widgets.FormToolkit;
import org.eclipse.ui.forms.widgets.Hyperlink;

public class FileChooser {

	protected Shell shell;
	private Text fileDirText;
	private Text fileNameText;
	private final FormToolkit formToolkit = new FormToolkit(Display.getDefault());

	/**
	 * Launch the application.
	 * @param args
	 */
	public static void main(String[] args) {
		try {
			FileChooser window = new FileChooser();
			window.open();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	/**
	 * Open the window.
	 */
	public void open() {
		Display display = Display.getDefault();
		createContents();
		shell.open();
		shell.layout();
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch()) {
				display.sleep();
			}
		}
	}

	/**
	 * Create contents of the window.
	 */
	protected void createContents() {
		shell = new Shell();
		shell.setSize(450, 300);
		shell.setText("开发异常网");
		
		Button button = new Button(shell, SWT.NONE);
		button.addSelectionListener(new SelectionAdapter() {
			@Override
			public void widgetSelected(SelectionEvent e) {
				FileDialog fileDialog=new FileDialog(shell);
				fileDialog.setText("chooser");
				fileDialog.open();
				fileDirText.setText(fileDialog.getFilterPath());
				fileNameText.setText(fileDialog.getFileName());
			}
		});
		button.setBounds(213, 77, 72, 22);
		button.setText("浏览");
		
		Label lblNewLabel = new Label(shell, SWT.NONE);
		lblNewLabel.setBounds(139, 127, 54, 12);
		lblNewLabel.setText("文件路径");
		
		fileDirText = new Text(shell, SWT.BORDER);
		fileDirText.setBounds(213, 127, 70, 18);
		
		Label lblNewLabel_1 = new Label(shell, SWT.NONE);
		lblNewLabel_1.setBounds(139, 173, 54, 12);
		lblNewLabel_1.setText("文件名");
		
		fileNameText = new Text(shell, SWT.BORDER);
		fileNameText.setBounds(215, 168, 70, 18);
		
		Hyperlink hprlnkNewHyperlink = formToolkit.createHyperlink(shell, "更多详情", SWT.NONE);
		hprlnkNewHyperlink.setBounds(139, 81, 63, 14);
		formToolkit.paintBordersFor(hprlnkNewHyperlink);
		hprlnkNewHyperlink.addHyperlinkListener(new HyperlinkAdapter(){

			@Override
			public void linkActivated(HyperlinkEvent e) {
				try {
				     Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler http://www.devexception.com/j2se/554187.htm/");
				    } catch (IOException e1) {
				     e1.printStackTrace();
				    }

			}
			
		});
	}
}

swt现在还更新吗，用的怎么样

研究这个，也是受人之托，帮忙做一个工具软件。感觉页面效果还是不错的。至于有没有更新，这个还真不太清楚呢。
