[英]How to cast a keyboard event
Where it says **spacebarpressed**
, I want to cast an event: 它说**spacebarpressed**
,我想投射一个事件:
public static void main(String[] args) throws IOException, AWTException{
final Robot robot = new Robot();
robot.delay(2000);
while(true)
{
if( **spacebarpressed** ) {
robot.mousePress(InputEvent.BUTTON1_MASK);
robot.mouseRelease(InputEvent.BUTTON1_MASK);
robot.delay(50);
}
else {
robot.delay(50);
}
}
}
You want to check if spacebar is pressed? 您要检查是否按下空格键吗? If that's so, you need an inner private class that implements KeyListener
, but you need to hook it up to a JFrame
however... I don't know about any other way. 如果是这样的话,您需要一个内部私有类来实现KeyListener
,但是您需要将其连接到JFrame
……我不知道其他任何方式。
private class Key
implements KeyListener
{
private boolean spacebarPressed = false;
@Override
public void keyTyped(KeyEvent e)
{
}
@Override
public void keyPressed(KeyEvent e)
{
if(e.getKeyCode() == KeyEvent.VK_SPACE)
{
spacebarPressed = true;
}
}
@Override
public void keyReleased(KeyEvent e)
{
if(e.getKeyCode() == KeyEvent.VK_SPACE)
{
spacebarPressed = false;
}
}
public boolean isSpacebarPressed()
{
return spacebarPressed;
}
}
And then just call isSpacebarPressed()
in your while loop to check. 然后只需在while循环中调用isSpacebarPressed()
即可进行检查。
