Java Keyboard Keycodes list

Question

Can anybody provide me with the Key Code integer list for individual keys used on the Keyboard for the KeyEvent class in java?

I want to create a dropdown list of all the keyboard keys for the user to select. I need the list specific to Keyboard. The VK constants does not help in this case because I need a 'list' of Keys used on the Keyboard. This post here didn't come of use because it's for Javascript and the codes aren't the same for all keys comparing with the javadoc. Also the KeyCode values used in javadoc are all arranged in Alphabetical Order, so it's hard to find the Keyboard keys over there. I tried googling for sources but nothing interesting came up just the Javascript one. Should I just compile them one by one myself or is there an easier way?

Edit: I know about VK. I need to use KeyEvent.getKeyText function to store each of the keyboard keys in a dropdown menu. So i need the list. That's why I asked should I need to compile them myself. I should have mentioned that earlier. It would be a waste of time doing that for each key.

Solution 1

KeyEvent class has static fields with these values.

For example, KeyEvent.VK_A represent "A" key.

To get the fields names you can use reflection:

Field[] fields = java.awt.event.KeyEvent.class.getDeclaredFields();
for (Field f : fields) {
    if (Modifier.isStatic(f.getModifiers())) {
        System.out.println(f.getName());
    } 
}

I generated it with this plain bruteforce:

import java.awt.event.KeyEvent;                                                               
import java.lang.reflect.Field;                                                               
import java.lang.reflect.Modifier;                                                            
import java.util.*;                                                                           
                                                                                              
public class Test {                                                                           
    public static void main(String[] a) {                                                     
        for(int i = 0; i < 1000000; ++i) {                                                    
            String text = java.awt.event.KeyEvent.getKeyText(i);                              
            if(!text.contains("Unknown keyCode: ")) {                                         
                System.out.println("" + i + " -- " + text);                                   
            }                                                                                 
        }                                                                                     
                                                                                              
    }                                                                                         
}

I have excluded the "unknown" codes.

Solution 3

You don't need to know the exact value of key codes. KeyEvent class has constants fields defining all the key codes:

KeyEvent.VK_A
KeyEvent.VK_ENTER
KeyEvent.VK_SPACE

etc.

Please read Javadoc carefully. All the constant values can also be found here:

http://docs.oracle.com/javase/7/docs/api/constant-values.html

Solution 4

You can try this program to get all the int values of the fields in the KeyEvent class

import java.awt.Robot; 
import java.awt.event.KeyEvent;
import java.awt.event.KeyEvent;
import java.lang.reflect.Field;
import java.lang.reflect.Modifier;
import java.util.*;
public class RobotClass 
{ 
   public static void main(String[] args)  
   {   
      ArrayList<Integer> values = new ArrayList<>();
      try{
         Robot robot = new Robot();
         Field[] fields = java.awt.event.KeyEvent.class.getDeclaredFields();
         for (Field f : fields) {
            if (Modifier.isStatic(f.getModifiers())) {
               values.add(f.getInt(f.getName()));
           } 
         }         
      }
      catch(Exception e){
         Collections.sort(values);
         for(int i:values) System.out.println(i);
      }
   } 
}

It doesn't help. I know about VK. My question was about compiling the list of KeyCodes rather than using each KeyCode. That's why I asked if i should compile them manually.

[Jean Waghetti]

Edited the answer. This will give the fields names. Then you'll need to "edit" the strings to put in the dropdown menu.

[Abdud Dayan Adeeb]

Thanks for your help. This is Perfect.

@AbdudDayanAdeeb, if this solved your problem then you should accept the answer.

I know it is old topic, but somebody may find this helpful

[Adam_G]

Thanks for this! Just curious where you pulled this from?

[radrow]

Just bruteforced all the keys to some reasonable number. Tbh this was just a random answer that I posted when I started to learn actual programming and it is still the most rated one out of all my posts
