真想掐死一个阿三，据调查薪水比我高，屁都不懂，lead developer, 最近一个
project due, 丫什么都做不出来，一出错就打电话来complain说有这样那样的问题，
也是我不好给他解释debug 过了一次，这下好过去的两周每天收到其SR的电话和email,
从中发现此人什么都不懂，想不通怎么会被雇佣的，而且还混了N年到现在的地位，
TNND我要是it的manager当场就要fire it..

I tried the following code, and looks like text.setText("test") caused
the "org.eclipse.swt.SWTException: Invalid thread access" error.
the UI here has text field, and a browser button, the browser button will
display JFileChooser to choose a file.
any idea how to get this work?
thanks.
testing code:
private void createContents(final Shell shell)
shell.setLayout(new GridLayout(3, false));
final Label lable = new Label(shell, SWT.READ_ONLY);
lable.setText("File Path");
final Text text = new Text(shell, SWT.SINGLE | SWT.BORDER);
text .setBounds(100, 75, 100, 20);
text .setTextLimit(150);
Button button = new Button(shell, SWT.PUSH);
button.setText("Browse...");
button.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent event) {

Display.getDefault().asyncExec(new Runnable() {

public void run()
{
JFileChooser jfc = new JFileChooser();
jfc.setFileSelectionMode(JFileChooser.FILES_ONLY);

jfc.setMultiSelectionEnabled(false);
int status = jfc.showOpenDialog(null);
if(status == JFileChooser.APPROVE_OPTION)
{
File browseFile = jfc.getSelectedFile();
text.setText("test");
}
}
});

}
});
