copied!<p>Ok guys, I've made some changes in my code as told by you. I have 3 classes:</p> <p>The second class (and first GUI): I have 4 <code>JButton</code>s - Simulare, CazParticular, Start and HandSelection, some <code>JLabel</code>s and 3 <code>JTextField</code>s; When I press the HandSelection button another frame it's created with different content.</p> <p>The 3rd class (and second GUI): I have 2 <code>JButton</code>s - Ok and Cancel and other stuff. When I press the Ok button I want to the access to the <code>JTextField(QuesHandText)</code> from the first Gui and use the method <code>setText()</code>. I can't figure this out, I'm thinking on this like 4-5 days and still can't get the answer. Please help me!</p> <p><img src="https://i.stack.imgur.com/S9JGS.jpg" alt="Screenshot"></p> <p>What code should I write in if statement to be able to modify the text in the <code>JTextField</code> from 2nd class (first GUI) ?</p> <h2>First class:</h2> <pre><code>import javax.swing.JFrame; public class Main { public static void main(String[] args){ //other stuff GuiMain gui = new GuiMain(); gui.frame1.setLocation(150,150); gui.frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); gui.frame1.setSize(400,250); gui.frame1.setResizable(false); gui.frame1.setVisible(true); //other stuff } } </code></pre> <h2>Second class:</h2> <pre><code>import java.awt.*; import java.awt.event.ActionListener; import java.awt.event.ActionEvent; import java.awt.event.ItemEvent; import java.awt.event.ItemListener; import java.awt.event.KeyEvent; import java.awt.event.KeyListener; import java.awt.event.WindowEvent; import javax.swing.*; public class GuiMain { public static GuiMain instance; public static GuiMain getInstance(){ if(GuiMain.instance == null){GuiMain.instance = new GuiMain();} return GuiMain.instance; } public JFrame frame1 = new JFrame(); public JTextField QuesHandText, FlopTurnRiverText, RezultatText; public JButton Simulare, CazParticular, Start, HandSelection; public int w1,h1; public JLabel someText; static int u=0; public int j=0; public GuiMain(){ frame1.setTitle("HoldemTool"); frame1.setLayout(null); QuesHandText = new JTextField(4); Simulare = new JButton("Simulare"); CazParticular = new JButton("Caz particular"); Start = new JButton("Start"); HandSelection = new JButton(new ImageIcon(getClass().getResource("GuiPic.png"))); Handler handler1 = new Handler(); CazParticular.addActionListener(handler1); Simulare.addActionListener(handler1); HandSelection.addActionListener(handler1); Start.addActionListener(handler1); QuesHandText.setEditable(false); FlopTurnRiverText.setEditable(false); RezultatText.setEditable(false); frame1.add(Welcome1); frame1.add(Welcome2); frame1.add(QuesHand); frame1.add(FlopTurnRiver); frame1.add(Rezultat); frame1.add(QuesHandText); frame1.add(FlopTurnRiverText); frame1.add(RezultatText); frame1.add(Simulare); frame1.add(CazParticular); frame1.add(Start); } public JTextField getQuesHandText(){ return QuesHandText; } public class Handler implements ActionListener{ public void actionPerformed(ActionEvent e){ if(e.getSource()==Simulare) { } if(e.getSource()==CazParticular){ QuesHandText.setEditable(true); FlopTurnRiverText.setEditable(true); QuesHandText.setText(""); FlopTurnRiverText.setText(""); RezultatText.setText(""); frame1.setSize(470, 250); Start.setBounds(3*FlopTurnRiverText.getX(), QuesHand.getY(), 65, h1); HandSelection.setBounds(3*FlopTurnRiverText.getX(), FlopTurnRiverText.getY(), 65, h1); frame1.add(HandSelection); frame1.add(Start); } if(e.getSource()==Start){ QuesHandText.setText("Text"); } if(e.getSource()==HandSelection){ GuiSelection gui2 = new GuiSelection(); gui2.frame2.setVisible(true); } } }} </code></pre> <h2>3rd class</h2> <pre><code>import java.awt.*; import java.awt.event.ActionListener; import java.awt.event.ActionEvent; import java.awt.event.ItemEvent; import java.awt.event.ItemListener; import java.awt.event.KeyEvent; import java.awt.event.KeyListener; import java.awt.event.WindowEvent; import javax.swing.*; public class GuiSelection extends GuiMain { JFrame frame2 = new JFrame(); GuiMain guiMain; public JButton Ok,Cancel; //other stuff public GuiSelection(){ guiMain = new GuiMain(); frame2.setTitle("Hand selection"); frame2.setSize(1135,535); frame2.setLayout(null); frame2.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame2.setVisible(true); frame2.setResizable(false); //other stuff Handler2 handler2 = new Handler2(); Ok.addActionListener(handler2); Cancel.addActionListener(handler2); frame2.add(Ok); frame2.add(Cancel); } public class Handler2 implements ActionListener{ public void actionPerformed(ActionEvent e){ if(e.getSource()==Cancel){ frame2.hide(); } if(e.getSource()==Ok) { GuiMain.getInstance().getQuesHandText().setText("From Ok"); //When I prees this button "Ok" I want to get access to the JTextField(QuesHandText) in the GuiMain class, and .setText(); //somothing like QuesHandtText.setText("someText"); } } } } </code></pre>
