jface中对话框返回数据给调用窗口

最近学习JFACE，在做一个POC的过程中，要用弹出对话框，填写数据，在关闭时，将数据传给调用窗口，
如果是一般的程序，或者用SWT的SHELL来做，是很简单的事，但确实不懂JFACE. 没办法，下班后，自己琢磨了一阵，发现自己真的老了，用类最基本的方法就可以解决，居然没有反应过来，get ,set 方法呀。晕呀。在 TitleAreaDialog 对话框的 ok 按钮上 把要传递的值给赋上，用get 方法来取。 废话少说，看代码最好了。

private Text picPathText;

private String picPath;
private int waterLeft;
private int waterTop;
/**

* @param parentShell
*/
public ImageWaterMarkDlg(Shell parentShell) {
super(parentShell);
}

@Override
protected Control createContents(Composite parent) {

super.createContents(parent);
setMessage("选择图片路径和输入图片水印的坐标,都必须填写!");
setTitle("图片水印设置");
return parent;


}

/**

@Override
protected Control createDialogArea(Composite parent) {
Composite area = (Composite) super.createDialogArea(parent);

public void widgetSelected(final SelectionEvent e) {

dlg.setFilterExtensions(new String[] {"*.bmp", "*.jpg", "*.tif", "*.*"});

if (fileName != null) {
picPathText.setText(fileName);
}


}
});
selectPicbutton.setText("...");
selectPicbutton.setBounds(435, 21, 30, 22);

final Label label_3 = new Label(container, SWT.NONE);
label_3.setText("(数字)");

final Label label_4 = new Label(container, SWT.NONE);
label_4.setText("(数字)");

//
return area;
}

/**

* @param parent
*/
@Override
protected void createButtonsForButtonBar(Composite parent) {
createButton(parent, IDialogConstants.OK_ID, "确定",
true);
createButton(parent, IDialogConstants.CANCEL_ID,
"取消", false);
}

/**
* Return the initial size of the dialog
*/
@Override
protected Point getInitialSize() {
return new Point(500, 293);
}
protected void buttonPressed(int buttonId) {
if (buttonId == IDialogConstants.OK_ID) {
picPath=picPathText.getText();
waterLeft=Integer.parseInt(waterLeftText.getText());
waterTop=Integer.parseInt(waterTopText.getText());
super.okPressed();
return;
}
super.buttonPressed(buttonId);
}

public String getPicPath() {
return picPath;
}


public int getWaterLeft() {
return waterLeft;
}



public int getWaterTop() {
return waterTop;
}



}

调用窗口的代码：
picWaterButton.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(final SelectionEvent e) {
ImageWaterMarkDlg imageWaterMarkDlg=new ImageWaterMarkDlg(getSite().getShell());
if (imageWaterMarkDlg.open()==Dialog.OK){
keyImage.AddImageWaterMark(imageWaterMarkDlg.getPicPath(),
imageWaterMarkDlg.getWaterLeft(), imageWaterMarkDlg.getWaterTop());
}

}
});

就这么简单，年纪大了，不服老都不行了，思维没有以前敏捷了。
