Passing RIGHT and LEFT

I'm writing a simple typewriter class, and i want to be able to pass the RIGHT and LEFT keys to it so I can change the cursor postion, but as soon as I pass the "key" variable RIGHT and LEFT don't work anymore..
Anybody know what i'm doing wrong?
Code:class Typewriter
{
String buffer = "";
int insert = 0;
Typewriter() {}
void type(int c)
{
switch(c){
case 8: delete(); break;
//case RIGHT: if(insert > 0) insert--; break;
//case LEFT: if(insert < buffer.length()) insert++; break;
case 13: // Avoid special keys
case 65535:
case 127:
case 27:
break;
default: buffer = buffer+(char)c; break;
}
}
void type(String s)
{
buffer = buffer+s;
}
void delete()
{
if(buffer.length() > 0) {
buffer = buffer.substring(0,buffer.length()-1);
}
}
} |

You have the Variable c as an int. You switch c. So c can't never be RIGTH or LEFT cause it's an int.

So are RIGHT and LEFT constants for chars then? If they're chars shouldn't they be castable to ints?
Sorry if this is obvious

Okay. i figured it out. It turns out that RIGHT and LEFT and all will work fine if you're using keyPressed, but I was using keyTyped, since it's a typewriter. I guess they just don't register in keyTyped..
Fry, is that intentional?

yeah, seems that sun handles the key codes differently for when it's keyTyped or keyPressed, so i need to modify things to work around that.
so, i'll move this over to bugs. should be an easy fix.
