Problem with event hadling in fullscreen mode
I made a fullscreen application and I'm trying to get it to respond to the mouse or keyboard input. The problem is it only responds a few second after I press the button. Does anyone know how I could speed up the response? All my code is posted below.
import java.awt.*;
import java.awt.event.*;
import java.awt.image.BufferStrategy;

privatestatic DisplayMode[] BEST_DISPLAY_MODES =new DisplayMode[]{
new DisplayMode(800, 600, 32, 0),
new DisplayMode(800, 600, 16, 0),
new DisplayMode(800, 600, 8, 0)
};
Frame mainFrame;
boolean done;
boolean pressed;
public LostHaven(GraphicsDevice device)
{
try
{
GraphicsConfiguration gc = device.getDefaultConfiguration();
mainFrame =new Frame(gc);
mainFrame.setUndecorated(true);
mainFrame.setIgnoreRepaint(true);
device.setFullScreenWindow(mainFrame);
if (device.isDisplayChangeSupported())
{
chooseBestDisplayMode(device);
}
mainFrame.addMouseListener(this);
mainFrame.addKeyListener(this);
mainFrame.createBufferStrategy(2);
BufferStrategy bufferStrategy = mainFrame.getBufferStrategy();
done =false;
pressed =false;
while (!done)
{
Graphics g = bufferStrategy.getDrawGraphics();
render(g);
g.dispose();
bufferStrategy.show();
}
}
catch (Exception e)
{
e.printStackTrace();
}
finally
{
device.setFullScreenWindow(null);
}
}
privatevoid render(Graphics g)
{
Rectangle bounds = mainFrame.getBounds();
g.setColor(Color.black);
g.fillRect(0,0,bounds.width, bounds.height);
g.setColor(Color.red);
g.fillRect(bounds.width*1/4, bounds.height*1/4, bounds.width*2/4, bounds.height*2/4);
if(pressed)
g.drawString("mouse pressed", 0, 15);
}
privatestatic DisplayMode getBestDisplayMode(GraphicsDevice device)
{
for (int x = 0; x < BEST_DISPLAY_MODES.length; x++)
{
DisplayMode[] modes = device.getDisplayModes();
for (int i = 0; i < modes.length; i++)
