使用SWT模拟鼠标键盘事件

    在SWT的snippets中有两个例子用来介绍这两个方法的使用，如下：

(1)、模拟鼠标事件
 * UI Automation (for testing tools) snippet: post mouse events
import org.eclipse.swt.*;

public class Snippet142 {

public static void main(String[] args) {
 final Display display = new Display();
 final Shell shell = new Shell(display);
 final Button button = new Button(shell,SWT.NONE);
 button.setSize(100,100);
 button.setText("Click");
 shell.pack();
 shell.open();
 button.addListener(SWT.MouseDown, new Listener() {
  public void handleEvent(Event e){
   System.out.println("Mouse Down (button: " + e.button + " x: " + e.x + " y: " + e.y + ")");
  }
 });
 final Point pt = display.map(shell, null, 50, 50);
 new Thread(){
  Event event;
  public void run(){
   try {
    Thread.sleep(300);
   } catch (InterruptedException e) {}
   event = new Event();
   event.type = SWT.MouseMove;
   event.x = pt.x;
   event.y = pt.y;
   display.post(event);
   try {
    Thread.sleep(300);
   } catch (InterruptedException e) {}
   event.type = SWT.MouseDown;
   event.button = 1;
   display.post(event);
   try {
    Thread.sleep(300);
   } catch (InterruptedException e) {}
   event.type = SWT.MouseUp;
   display.post(event);
  } 
 }.start();
 while (!shell.isDisposed()) {
  if (!display.readAndDispatch()) display.sleep();
 }
 display.dispose();
}
}
(2)、模拟键盘事件

 * UI Automation (for testing tools) snippet: post key events
import org.eclipse.swt.*;

public class Snippet146 {

public static void main(String[] args) {
 final Display display = new Display();
 final Shell shell = new Shell(display);
 final Text text = new Text(shell, SWT.BORDER);
 text.setSize(text.computeSize(150, SWT.DEFAULT));
 shell.pack();
 shell.open();
 new Thread(){
  public void run(){
   String string = "Love the method.";
   for (int i = 0; i < string.length(); i++) {
    char ch = string.charAt(i);
    boolean shift = Character.isUpperCase(ch);
    ch = Character.toLowerCase(ch);
    if (shift) {
     Event event = new Event();
     event.type = SWT.KeyDown;
     event.keyCode = SWT.SHIFT;
     display.post(event); 
    }
    Event event = new Event();
    event.type = SWT.KeyDown;
    event.character = ch;
    display.post(event);
    try {
     Thread.sleep(10);
    } catch (InterruptedException e) {}
    event.type = SWT.KeyUp;
    display.post(event);
    try {
     Thread.sleep(100);
    } catch (InterruptedException e) {}
    if (shift) {
     event = new Event();
     event.type = SWT.KeyUp;
     event.keyCode = SWT.SHIFT;
     display.post(event); 
    }
   }
  } 
 }.start();
 while (!shell.isDisposed()) {
  if (!display.readAndDispatch()) display.sleep();
 }
 display.dispose();
}
}

两种方法中都是先声明一个Event，然后将该Event的type类型设置为对应的SWT.KeyUp/KeyDown/MouseUp/MouseDown，最后通过Display类的post（Event）方法来模拟对应的事件。注意：如果有多个控件，需要得到对应控件的display属性，然后post该事件。例如，在一个窗口中有一个Browser，则需要使用thisClass.browser.getDisplay().post(event)。
