Hola, tengo está clase de java donde utilizo el teclado como comando, y me gustaria para los mismos comando, en vez con el teclado usando botones. Si alguien me puede echar una mano:

import java.awt.KeyEventDispatcher;
import java.awt.event.KeyEvent;

public class ControlTeclado implements KeyEventDispatcher, Runnable {
private VueloDrone af = null;
private Thread controller;
private boolean stop;
private boolean hascontrol = false;

float speed = 0.4f;
float theta = 0;
float phi = 0;
float gaz = 0;
float yaw = 0;

public ControlTeclado(VueloDrone af) {
this.af = af;
}

public void start() {
controller = new Thread(this);
controller.start();
stop = false;
}

public void stop() {
stop = true;
}

public boolean dispatchKeyEvent(KeyEvent e) {
if (e.getID() == KeyEvent.KEY_PRESSED) {

switch(e.getKeyCode()) {
case KeyEvent.VK_P:

af.takePhoto();

break;

case KeyEvent.VK_R:

af.toggleRecording();


break;

case KeyEvent.VK_T:

af.toggleRecordingOnUSB();


break;

case KeyEvent.VK_PAGE_UP:
if(speed + 0.1f < 1.05f) {
speed += 0.1f;
}
break;

case KeyEvent.VK_PAGE_DOWN:
if(speed - 0.1f > 0.05f) {
speed -= 0.1f;
}
break;

case KeyEvent.VK_F5:

af.takeOff();


break;

case KeyEvent.VK_F6:

af.land();


break;



case KeyEvent.VK_F12:

af.emergency();
break;

case KeyEvent.VK_F:

af.flip();
VueloDrone.append("Flip!");
break;

case KeyEvent.VK_W:
theta = -speed;
break;

case KeyEvent.VK_S:
theta = speed;
break;

case KeyEvent.VK_A:
phi = -speed;
break;

case KeyEvent.VK_D:
phi = speed;
break;

case KeyEvent.VK_UP:
gaz = speed;
break;

case KeyEvent.VK_DOWN:
gaz = -speed;
break;

case KeyEvent.VK_LEFT:
yaw = -0.8f;
break;

case KeyEvent.VK_RIGHT:
yaw = 0.8f;
break;

}
//}
if(e.getKeyCode() == KeyEvent.VK_CONTROL) {
setControl(true);
}
if(e.isAltDown()) {
if(!af.isScriptExecuting()) {
for(int i = 0; i < af.shortcuts.size(); i++) {
if(Character.toUpperCase(e.getKeyChar()) == ((char) af.shortcuts.get(i)[2])) {
af.runScriptFromShortcut(i);
}
}
}
}
if(e.getKeyCode() == KeyEvent.VK_F1) {
af.requestUserControl();
}

if(e.getKeyCode() == KeyEvent.VK_ESCAPE) {
af.leaveFullscreenMode();
af.video.toggleHUD();
}
if(e.getKeyCode() == KeyEvent.VK_ENTER) {
if(e.isAltDown()){
af.enterFullscreenMode();
af.video.toggleHUD();
}}


if(e.getKeyCode() == KeyEvent.VK_F3) {
af.video.toggleDebugInfo();
af.toggleDebugInfo();
}
} else if (e.getID() == KeyEvent.KEY_RELEASED) {
switch(e.getKeyCode()) {
case KeyEvent.VK_W:
theta = 0;
break;

case KeyEvent.VK_S:
theta = 0;
break;

case KeyEvent.VK_A:

break;

case KeyEvent.VK_D:

break;

}
if(e.getKeyCode() == KeyEvent.VK_CONTROL) {

af.ctrler_move(0, 0, 0, 0);
}
} else if (e.getID() == KeyEvent.KEY_TYPED) {

}

return false;
}

public void setControl(boolean hascontrol) {
this.hascontrol = hascontrol;
if(af.ctrlpoll != null) {
af.ctrlpoll.setControl(!hascontrol);
}
}

}

public void run() {

if(hasControl()) {
af.ctrler_move(phi, theta, gaz, yaw);
}

try {
Thread.sleep(10);
} catch(InterruptedException e) {

}
}
}
