二、使用SWT中的鼠标键盘事件

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)。
