    Default [SOLVED] Compress my Code!

    Hi;

    I have this code:

    public class Lab3 extends JFrame {
     
        /**
         * Creates new form Lab3
         */
        public Lab3() {
            initComponents();
            txtArea.addActionListener(new ActionListener() {
     
                public void actionPerformed(ActionEvent event) {
                    String usrInput = txtArea.getText();
                    usrInput = usrInput.trim();
     
                    txtAreaChange.setText(usrInput);
     
                }
            });
     
            cmdReset.addActionListener(new ActionListener() {
     
                public void actionPerformed(ActionEvent event) {
                    String usrResult = txtAreaChange.getText();
     
                    txtAreaChange.setText("");
                    txtArea.setText("");
                }
            });
     
            ButtonActions btnAct = new ButtonActions();
            btnSmall.addMouseListener(btnAct);
        }
     
        public class ButtonActions implements MouseListener{
     
            public void mouseClicked(MouseEvent event) {
                String usrInput = txtArea.getText();
                usrInput = usrInput.trim();
                txtAreaChange.setText(usrInput);
                Font oldFont = txtAreaChange.getFont();
                Font newFont = new Font(oldFont.getName(), oldFont.getStyle(), 12);
                txtAreaChange.setFont(newFont);
            }
     
            public void mousePressed(MouseEvent event) {
            }
     
            public void mouseReleased(MouseEvent event) {
            }
     
            public void mouseEntered(MouseEvent event) {
            }
     
            public void mouseExited(MouseEvent event) {
            }
        }

    I am currently using NetBeans IDE and using a the JFrame Form to create a GUI.

    Now I know that it is the easy way out, but I'm going to need to refresh my memory based on the layout classes in the weeks to come, so far I have settled with this.

    Now my GUI looks like this:



    The process may not be clear if not already.

    In this next screenshot:



    Now instead of myself copy and pasting the ButtonActions Method over and over again for the remaining radio/checkbox buttons.

    I want to be able to incorporate an If Statement within the ButtonActions Method, inside the mouseClicked Method. To be able to indicate which button is clicked and perform the necessary code given within the block.(Implementing ActionListener as well)


    variables:

    btnSmall = Small Radio Button
    btnMedium = Medium Radio Button
    btnLarge = Large Radio Button


    PS.C:

    void mouseClicked(MouseEvent event)
    {
    String usrInput = txtArea.getText();
    usrInput = usrInput.trim();
    txtAreaChange.setText(usrInput);
    Font oldFont = txtAreaChange.getFont();

    if(event.getSource()==btnSmall)
    {
    Font newFont = new Font(oldFont.getName(), oldFont.getStyle(), 12);
    txtAreaChange.setFont(newFont);
    }
    else if(event.getSource()==btnMedium)
    {
    Font newFont = new Font(oldFont.getName(), oldFont.getStyle(), 14);
    txtAreaChange.setFont(newFont);
    }
    else if(event.getSource()==btnLarge)
    {
    Font newFont = new Font(oldFont.getName(), oldFont.getStyle(), 24);
    txtAreaChange.setFont(newFont);
    }
    else
    {
    keep txtAreaChange the same.
    }

    I'm not sure if this is being clear enough. If any clarity is needed I will respond a.s.a.p.

    Thank you for looking at this post!

    Can you explain what your problem is? The last posted code looks like it does what you are asking about.

    The last posted code was just a pseudo I came up with.
    I tried doing what I typed in there but I get an error when I tried to event.getSource()==btnSmall.
    It says it cannot recognize it.

    What was not recognized?

    Make sure all variables are in scope.

    I tried this:

        public class ButtonActions implements MouseListener, ActionListener {
     
            public void mouseClicked(MouseEvent event) {
                String usrInput = txtArea.getText();
                usrInput = usrInput.trim();
                txtAreaChange.setText(usrInput);
                Font oldFont = txtAreaChange.getFont();
                public void actionPerformed(ActionEvent eventq)
                {
                if (eventq.getSource() == btnSmall) {
                    Font newFont = new Font(oldFont.getName(), oldFont.getStyle(), 12);
                    txtAreaChange.setFont(newFont);
                } else if (eventq.getSource() == btnMedium) {
                    Font newFont = new Font(oldFont.getName(), oldFont.getStyle(), 14);
                    txtAreaChange.setFont(newFont);
                } else if (eventq.getSource() == btnLarge) {
                    Font newFont = new Font(oldFont.getName(), oldFont.getStyle(), 24);
                    txtAreaChange.setFont(newFont);
                }
                }
            }
     
            public void mousePressed(MouseEvent event) {
            }
     
            public void mouseReleased(MouseEvent event) {
            }
     
            public void mouseEntered(MouseEvent event) {
            }
     
            public void mouseExited(MouseEvent event) {
            }
        }

    I get an error over ButtonActions saying I have not overwritten the mouseExited method yet.
    Also I get an error within the mouseClicked method which are my variables becoming unrecognized, and I'm unable to create Font Objects as well.

    saying I have not overwritten the mouseExited method
    You must override ALL methods in an interface that you implement.

    my variables becoming unrecognized,
    What variables? Are they defined and are their definitions in scope for where you are trying to use them.

    These are the list of variables that I am using:

        private javax.swing.JCheckBox btnBold;
        private javax.swing.JRadioButton btnCentre;
        private javax.swing.JCheckBox btnItalic;
        private javax.swing.JRadioButton btnLarge;
        private javax.swing.JRadioButton btnLeft;
        private javax.swing.JRadioButton btnMedium;
        private javax.swing.JRadioButton btnRight;
        private javax.swing.JRadioButton btnSmall;
        private javax.swing.JComboBox cmbBack;
        private javax.swing.JComboBox cmbFore;
        private javax.swing.JButton cmdExit;
        private javax.swing.JButton cmdReset;
        private javax.swing.ButtonGroup grpAlign;
        private javax.swing.ButtonGroup grpTxtSize;
        private javax.swing.JLabel lblAign;
        private javax.swing.JLabel lblBackground;
        private javax.swing.JLabel lblChangeTxt;
        private javax.swing.JLabel lblFont;
        private javax.swing.JLabel lblForeground;
        private javax.swing.JLabel lblTextSize;
        private javax.swing.JPanel pnlBot;
        private javax.swing.JPanel pnlMid;
        private javax.swing.JPanel pnlRight;
        private javax.swing.JPanel pnlTopLeft;
        private javax.swing.JTextField txtArea;
        private javax.swing.JTextField txtAreaChange;

    These are all in the same class.

    After I implemented the MouseListener class for the ButtonsAction method I put all the necessary methods within that method.

    Please post the full text of the error messages.
    If the compiler says there is an error, I believe the compiler. I need to see the full text of what the compiler is saying.
    I can not tell how the bits and pieces of your code are connected.

    I put all the necessary methods within that method.
    You can not nest method definitions within other method definitions.

    If possible, paste the whole code here so that we could see the scope. Otherwise, paste the exception/error message here.

    Where is the full text of the error messages?


    I put all the necessary methods within that method.
    You can not nest method definitions within other method definitions.

    public class ButtonActions implements MouseListener, ActionListener{

    public void mouseClicked(MouseEvent event) {
    public void actionPerformed(ActionEvent event)
    {
    String usrInput = txtArea.getText();
    usrInput = usrInput.trim();
    txtAreaChange.setText(usrInput);
    Font oldFont = txtAreaChange.getFont();
    if(event.getSource()==btnSmall)
    {
    Font newFont = new Font(oldFont.getName(), oldFont.getStyle(), 12);
    txtAreaChange.setFont(newFont);
    }
    }
    In your code, compiler is unable to find the abstract method actionPerformed(...) for ActionListener interface as it's nested inside the mouseClicked(...)
    Implement mouseClicked(...) and actionPerformed(...) separately.

    Can you use the javac compiler program to compile your program? The IDE's output does not show the source lines where the errors are.
    Here is a sample of the output from the javac program:
    TestSorts.java:138: cannot find symbol
    symbol  : variable var
    location: class TestSorts
             var = 2;
             ^

    .txtAreaActions.ButtonActions is not abstract and does not override abstract method mouseExited
    This part of the message says that your code does not correctly implement all the methods for the interface it implements. See post#6

       public class ButtonActions implements MouseListener, ActionListener {
     
            public void actionPerformed(ActionEvent event) {
                if (event.getSource() == btnSmall) {
     
                    Font newFont = new Font(oldFont.getName(), oldFont.getStyle(), 12);
                    txtAreaChange.setFont(newFont);

                Font oldFont = txtAreaChange.getFont();
     
            }

    I'm not being able to instantiate the font class? :S

    I found the issue on why it would not instantiate.

    public class Lab3 extends JFrame {
     
        /**
         * Creates new form Lab3
         */
        public Lab3() {
            initComponents();
     
            txtAreaActions txtAreaAct = new txtAreaActions();
            txtArea.addActionListener(txtAreaAct);
     
            clearAll clear = new clearAll();
            cmdReset.addActionListener(clear);
     
            exit exitWindow = new exit();
            cmdExit.addActionListener(exitWindow);
     
            ButtonActions btnAct = new ButtonActions();
            btnSmall.addMouseListener(btnAct);
            btnSmall.addActionListener(btnAct);
        }
     
        public class txtAreaActions implements ActionListener {
     
            public void actionPerformed(ActionEvent event) {
                String usrInput = txtArea.getText();
                usrInput = usrInput.trim();
     
                txtAreaChange.setText(usrInput);
     
            }
        }
     
        public class clearAll implements ActionListener {
     
            public void actionPerformed(ActionEvent event) {
                String usrResult = txtAreaChange.getText();
     
                txtAreaChange.setText("");
                txtArea.setText("");
            }
        }
     
        public class exit extends JOptionPane implements ActionListener {
     
            public void actionPerformed(ActionEvent event) {
                int answer = JOptionPane.showConfirmDialog(null, "Are you sure you want to Exit?", "Exit", JOptionPane.YES_NO_OPTION);
                if (answer == 0) {
                    System.exit(answer);
                }
            }
        }
     
        public class ButtonActions implements MouseListener, ActionListener {
     
            public void actionPerformed(ActionEvent event) {
                if (event.getSource() == btnSmall) {
                    Font oldFont = txtAreaChange.getFont();
                    Font newFont = new Font(oldFont.getName(), oldFont.getStyle(), 12);
                    txtAreaChange.setFont(newFont);
                }else if(event.getSource()==btnMedium){
                       Font oldFont = txtAreaChange.getFont();
                    Font newFont = new Font(oldFont.getName(), oldFont.getStyle(), 16);
                    txtAreaChange.setFont(newFont);
    }
            }
     
            public void mouseClicked(MouseEvent event) {
                String usrInput = txtArea.getText();
                usrInput = usrInput.trim();
                txtAreaChange.setText(usrInput);
                Font oldFont = txtAreaChange.getFont();
     
            }
     
            public void mousePressed(MouseEvent event) {
            }
     
            public void mouseReleased(MouseEvent event) {
            }
     
            public void mouseEntered(MouseEvent event) {
            }
     
            public void mouseExited(MouseEvent event) {
            }
        }

    So far I have no errors. But I'm wondering how am I going to make it when I mouseClick, it will use the actionPerformed method to determine which Radio Button is pressed?

    Why are you having the two listeners on a button?

    I was just testing to see if it would make a difference.
    Is there a way for my 'above post' possible?

    What happens when you execute the code an click on the button?
    Add printlns to each listener and see when/if they are called.

    With the two listeners on the button and I added printlns to each Listener. It does print out.

    Foolish of myself, the default size output without a Radio Button being pressed is 12, and the font settings for the Small Radio Button is to change the font size to 12.

    It is now working and I tried adding the Medium radio button to do the same thing. So far so good! The if Statement is doing the job.


    Thank you Norm & Mr.777 for taking your time to help with my situation.
