Hello,
I'm developing a Slide Image Puzzle in Java. I'm randomly shuffling the Image in a for loop and I want the Image to be painted on the screen after each iteration of the for loop. Using repaint() doesn't work so I'm wondering how I can implement paintImmediately() to do this.
Here's a simplified version of my program structure
1. ImageGame class - main app
2. ImageFrame class - JFrame
3. ImagePanel class - JPanel
The repaint() doesn't work in the loop because Java only performs the repaint() at the last iteration. Therefore, I want to use paintImmediately() to paint the panel at every iteration so that the user can see how the tiles are being swapped. I understand that paintImmediately() can only be called from the EDT (event dispatch thread) so my guess is that it needs to be in the ImageFrame() class in the ActionPerformed(). I can't figure out how to do this!
Does anyone know how it can be implemented?
Thanks in advance!

Code:
class ImageGame{
[INDENT]public static void main() {
[INDENT]//creates and displays a new ImageFrame (extends JFrame)[/INDENT]
}[/INDENT]
}2. ImageFrame class - JFrame
Code:
class ImageFrame extends JFrame{
[INDENT]ImagePanel panel = new ImagePanel(); //creates panel
//has a menu with options "loadImage" and "shuffleImage"
[INDENT]public void actionPerformed(ActionEvent evt)
{
Object source = evt.getSource();
[INDENT]if(source==loadimage)
{
panel.loadimage();
}[/INDENT]
[INDENT]if(source==shuffleimage)
{
panel.ShuffleImage();
}[/INDENT]
}
[/INDENT][/INDENT]
}3. ImagePanel class - JPanel
Code:
class ImagePanel extends JPanel{
[INDENT]//setting up the Panel
[INDENT]public void paintComponent(Graphics g) //works fine
{
super.paintComponent(g);
if (image != null)
{
g.drawImage(image, 0, 0, null); }
}[/INDENT]
[INDENT]public void loadimage()
{
//code to load the image
}[/INDENT]
public void shuffleImage()
[INDENT]{
[INDENT]for(i=0;i<x;i++)
{
//swap adjacent x and x-1
repaint()
Thread.sleep(delay);
}[/INDENT]
}[/INDENT][/INDENT]
