Frame resets when label or text change

I am currently having some problem in some javaFrame application. It is a simple game where the ball is running around and there is one button which starts and stops the ball. The problem is whenever i change the text of a label or a button while the ball is running the frame resets(the ball is resetting where it was in the first place) and i don't want that to happen. I created the frame and the panel by dragging from the side(i did not write code to create frame and panels). I don't know all the rules in this site and i don't know if it is permissible but i could not find any ways to show this to you so i linked 2 short youtube videos at the end so you can see what it is(i apologize for that).
What i did in frame:
Created 2 panels.
Added a button to panel1(upper one) and added ball image on top of it.
Added 2 buttons on panel2(lower one) which are Start/Stop and changeLabel.

How to change the values of spinner and radio button if I click on a row from jtable (must depend on the values form jtable)

If I click a row(JTABLE), it must display the specific values back to the textfields/combobox/radiobutton/spinner. But in my case, it's just hard to retrieve the values back to the RADIO BUTTON and SPINNER.

How to change the values of spinner and radio button
The spinner should be easily settable by calling its setValue(...) method, and passing in the number from the selected table row item.
For the JRadioButtons, probably the easiest solution is to use a Map that maps the selection to its radio button, and then using this map to get a reference to the proper JRadioButton, and calling setSelected(true) on it.
For an example, and for an example of a Minimal, Complete, and Verifiable example, please have a look at:

JTextField resizing after setting text that is longer than its initial size?

This is what the textfield looks like before clicking the check button:
This is what happens after clicking check. This only happens with a string that is longer than the textfield.

vlcj application optimization

Hi friends I'm actually developing my own video player, using VLCJ libraries , I use a canvas over a JFrame and a options bar with buttons to play,stop etc..
in this moment the video player and all the buttons works, but
it is so slow and the fps are so low too, I think that using a canvas is not the best method to play videos , or maybe my code is not optimized .
Main class:
package vlcvideo;

File ourFile;
//seleccionar la ruta de instalacion del vlc
/*filex.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);//selecciona solo directorios
filex.showSaveDialog(null);
ourFile=filex.getSelectedFile();
rutaVlc=ourFile.getAbsolutePath();*/
/*
filex.setFileSelectionMode(JFileChooser.FILES_ONLY);
filex.showSaveDialog(null);
ourFile=filex.getSelectedFile();
rutaVideo=ourFile.getAbsolutePath();*/
System.out.println(rutaVlc + "ruta DLL");
System.out.println(rutaVideo + " ruta video");
//new MediaPlayer(rutaVlc,rutaVideo).run();

You have a tight loop in your thread that will consume just about all of your CPU.
Rather than polling inside a tight loop you should use media player events to get the information you want.
Or at worst you should sleep in that loop.

Accessing elements from a jFrame that is within a running instance of a thread

I am trying to make an app for communicating between different running instances of a thread. I have a jFrame that has a jTextField and a jButton. In the jTextField I type the number of threads that I want to run and after I press the jButton the threads run. Each thread contains a jFrame with a jButton. So if I type 3 in the jTextField and then press OK, three different jFrames pop out that have an own jButton. If I press the jButton in one of the jFrames of the threads, the jButton is set to disabled (setEnabled(false)). This should happen to each jButton of the jFrames from within the threads when pressed but the one from the last jFrame that is still not pressed.
This is the window class for the thread:
public class Window extends JFrame implements Runnable {
JFrame jr;
JButton bt;
public void run() {
jr=new JFrame();
bt=new jButton();
bt.setTitle("Press Me");
jr.setLayout(new FlowLayout());
jr.add(bt);
bt.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e){
bt.setEnabled(false);
}
});
jr.setVisible(true);
}
}
Now this is how I run multiple instances of this thread. i is the number of the thread instances that is taken from the jTextField:
( int i=Integer.parseInt(jTextField1.gettext()) )
for (int a=0;a<i;a++) {
Runnable thr=new Window(a);
executor.execute(thr);
}
This is what I want to do: After I press the jButton on every jFrame that is within the thread instances and it is set to setEnabled(false) I get to the last jFrame that is popped up whose jButton is still unpressed. When I press this last JButton I want that all the JButtons on every jFrame to be set back to setEnabled(true). How can I do that?

This is the main class it works 100 % now!
