最近在學(xué)習(xí)SWT/JFace,在做一個(gè)小東西的時(shí)候需要模擬鼠標(biāo)鍵盤事件,在網(wǎng)上搜了一下,在java中模擬這些事件,主要有兩種方法:
一、使用AWT中的Robot類
Robot
java.lang.Object
java.awt.Robot
-
public class Robot
- extends Object
此類用于為測試自動(dòng)化、自運(yùn)行演示程序和其他需要控制鼠標(biāo)和鍵盤的應(yīng)用程序生成本機(jī)系統(tǒng)輸入事件。Robot 的主要目的是便于 Java 平臺(tái)實(shí)現(xiàn)自動(dòng)測試。類中幾個(gè)主要的模擬函數(shù)如下:
void |
keyPress(int keycode)
按下給定的鍵。 |
void |
keyRelease(int keycode)
釋放給定的鍵。 |
void |
mouseMove(int x, int y)
將鼠標(biāo)指針移動(dòng)到給定屏幕坐標(biāo)。 |
void |
mousePress(int buttons)
按下一個(gè)或多個(gè)鼠標(biāo)按鈕。 |
void |
mouseRelease(int buttons)
釋放一個(gè)或多個(gè)鼠標(biāo)按鈕。 |
void |
mouseWheel(int wheelAmt)
在配有滾輪的鼠標(biāo)上旋轉(zhuǎn)滾輪。 |
二、使用SWT中的鼠標(biāo)鍵盤事件
在SWT的snippets中有兩個(gè)例子用來介紹這兩個(gè)方法的使用,如下:
(1)、模擬鼠標(biāo)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)、模擬鍵盤事件
* 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();
}
}
兩種方法中都是先聲明一個(gè)Event,然后將該Event的type類型設(shè)置為對(duì)應(yīng)的
SWT.KeyUp/KeyDown/MouseUp/MouseDown,最后通過Display類的post(Event)方法來模擬對(duì)應(yīng)的事件。注
意:如果有多個(gè)控件,需要得到對(duì)應(yīng)控件的display屬性,然后post該事件。例如,在一個(gè)窗口中有一個(gè)Browser,則需要使用
thisClass.browser.getDisplay().post(event)。
