SWT/Jface 图片自动缩放的例子

本文主要是介绍SWT/Jface 图片自动缩放的例子，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

原创的例子 图片是做到label上了  其实控件的原理是通的 大家想放哪就放哪 哈哈

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.PaintEvent;
import org.eclipse.swt.events.PaintListener;
import org.eclipse.swt.graphics.Image;
import org.eclipse.swt.graphics.Point;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;

/**
 * @Title: ImageTest.java
 * @Description: TODO

public class ImageTest {
 public static void main(String[] args) {
  Display display = new Display();
  final Shell shell = new Shell(display);
  shell.setSize(600,300);
  shell.setLayout(new GridLayout());

  final Label label = new Label(shell, SWT.BORDER);
  label.setLayoutData(new GridData(GridData.FILL_BOTH));
  final Image image = new Image(display, "icons/test.jpg");
  label.setImage(image);
  label.addPaintListener(new PaintListener() {
   @Override
   public void paintControl(PaintEvent e) {
    Point size = label.getSize();
    Point p = label.getLocation();
    e.gc.drawImage(image, 0, 0, 512, 78, p.x, p.y, size.x, size.y);
   }
  });
  shell.open();
  while (!shell.isDisposed()) {
   if (!display.readAndDispatch())
    display.sleep();
  }
  display.dispose();

 }
}
