KeyListener - Is this what I need?

[dbashby]

I have an application in netbeans, has a help key on it, I want it so that if a user presses f1 at any point in the running of the app that the help screen comes up which works if you press the button.

Is a keylistener what I need for this?

Thanks in advance

[dbashby]

I have tried a couple of sets of code

public void keyPressed(KeyEvent e){
        int F1;

        if (e.getKeyCode() == e.VK_F1);
                {
                 optPane1.showMessageDialog(this,
                    " You can use your mouse or tab key to navigate\n"+
                    " our body mass calculator.\n\n"+
                    " New button, this will overwrite all previous\n" +
                    " files\n\n"+
                    " Add Record, enables you to add a new member\n" +
                    " to the records only after creating new file.\n\n"+
                    " Search button, enter your membership number \n" +
                    " click search to find member details.\n\n"+
                    " Update Button, Search for the appropriate record\n"+
                    " by membership number, amend the details\n"+
                    " then click the update button\n\n"+
                    " Select Imperial or Metric for the measurements,\n" +
                    " enter the height and weight then click convert\n\n"+
                    " The default measurements are metric, if you \n"+
                    " select imperial using the radio button you \n"+
                    " will be advised."+
                    " \n","User Guide",optPane1.INFORMATION_MESSAGE);}

    }

From the code at the top I have tried the getkey and keyListener both but neither seems to work, could someone just advise as to which method i should be following to produce the effect that I am wanting

which is on press of f1 the help screen opens up

Thanks in advance

You could use a keylistener to trigger the display of your help menu, but key binding might be better... Reason being is that key bindings override the current action of the key, while a keylistener lets you know when the key is pressed, released, etc... The current action of the key is still preformed...

Check out:
How to Use Key Bindings (The Java™ Tutorials > Creating a GUI with JFC/Swing > Using Other Swing Features)

Let me know if you get stuck...

Thanks for the info, I am just taking a look now....I am sure at some point I will be back at least to clarify something..

Ok, so far I have

if component.getInputMap().put(KeyStroke("F1"));

The code may not be right at the moment but the question I have is, can this be put in the code for the button or does it have to go in public?

private void cmdHelpActionPerformed(java.awt.event.ActionEvent evt) {                                        
                 // Instructions on how to use this application
        
        if component.getInputMap().put(KeyStroke("F1"));
              //if(evt.getSource()==cmdHelp);
                { 
                 optPane1.showMessageDialog(this,                        
                    " You can use your mouse or tab key to navigate\n"+
                    " our body mass calculator.\n\n"+
                    " New button, this will overwrite all previous\n" +
                    " files\n\n"+
                    " Add Record, enables you to add a new member\n" +
                    " to the records only after creating new file.\n\n"+
                    " Search button, enter your membership number \n" +
                    " click search to find member details.\n\n"+
                    " Update Button, Search for the appropriate record\n"+
                    " by membership number, amend the details\n"+
                    " then click the update button\n\n"+                    
                    " Select Imperial or Metric for the measurements,\n" +
                    " enter the height and weight then click convert\n\n"+
                    " The default measurements are metric, if you \n"+
                    " select imperial using the radio button you \n"+
                    " will be advised."+
                    " \n","User Guide",optPane1.INFORMATION_MESSAGE);}
    }

I dont need the answer to the final solution yet, I am hopeing that I can figure it out but could you answer me as to whether it has to be public or not?

Thanks in advance

[markw8500]

You can make it private...

[dbashby]

But can I have it working within the Help button code or do I need to seperate it?

I have had a look at several examples of scripts with the event, I am trying to validate it at the moment in the help button but I have the feeling that this will never work, is this the case?

[markw8500]

You can have your program do just about anything you want... You just need to have enough patience...

For your button... All you would need to do is:

       JButton b = new JButton();

        b.addActionListener(new ActionListener(){

            public void actionPerformed(ActionEvent e) {
                
                
                //Display HelpMenu...
                
            }
            
            
            
            
        });

Then you want to use key bindings to override the action of the F1 key...

[dbashby]

Well I am surrounded by books, googled myself to death but I have not been able to make working sense of this, I know the answer when I eventually get there will probably only be 4 or 5 lines of code but currently I have been jargoned to death.

I need a little more help!!

Thanks in advance

[markw8500]

No Prob...

       this.getInputMap(JComponent.WHEN_FOCUSED).put(KeyStroke.getKeyStroke("F1"), f1Action.getValue(Action.NAME));

        this.getActionMap().put(f1Action.getValue(Action.NAME), f1Action);




     public Action f1Action = new AbstractAction("DisplayHelpMenu") {

        public void actionPerformed(ActionEvent e) {

            DisplayHelpMenu();
        }


    };

That should do the trick...

[dbashby]

well I hate to admit it but no matter where I put this I get errors, I know it is going to be me but I have tried placing the code in the public class at the start of my code which gives me an error on the line below

this.getActionMap().put(f1Action.getValue(Action.NAME), f1Action);

the error I am getting is 'illegal start of expression'

Thanks for the help so far but can I ask for more..... :D

[markw8500]

You dont have to ask...

Replace this with the component that you want the f1Action to work... For instance if I have a JFrame with a JTable in it... I want to do this:

       JTable jt = new JTable();

       jt.getInputMap(JComponent.WHEN_FOCUSED).put(KeyStroke.getKeyStroke("F1"), f1Action.getValue(Action.NAME));

        jt.getActionMap().put(f1Action.getValue(Action.NAME), f1Action);

Now if the JTable (jt) has focus then when I press F1 the help menu will pop up...

Post your code and lets take a look...

[dbashby]

Well I will post the code but its a very large amount, is there a particular part you want or do u want it all?

This application is nearly complete, in total there are 1537 lines of code bearing in mind a lot of it is netbeans.

[markw8500]

I see... Well it cant hurt... Post it all and if we need to reduce it to a particular part we can do it at that time...

[dbashby]

It wont let me post all the code, tried to attach a .txt, was told file exceeds limit so have to cut it into sections

I recommend that you just extract the code of interest and place it in a separate compilable program without netbeans code. That way we'll have less code to go through and your chances of getting an answer quick will be increased. Have a look at this to see what I'm talking about: SSCCE
