The field "name" doesnt apparently exsist :/

[Addez]

This code:

try {
				f.getClass().getField(txt).set(txt,real.substring(0,i));
			} catch (Exception e) {
				e.printStackTrace();
			}

Gives this error:

Can not set java.lang.String field Window.name to java.lang.String

Ehh wut?!

Why cant it assign a string, to a string object?

[eRaaaa]

Because you dont read the API Doc *g*
--> Field.set

Parameters:
obj - the object whose field should be modified
value - the new value for the field of obj being modified

try: set(f,real.substring(0,i));

This code:

try {

Gives this error:

Can not set java.lang.String field Window.name to java.lang.String

Ehh wut?!

You are referencing an incorrect object 'txt' in your getField( ... ) method; it should refer to the object to which you want to set its field. b.t.w. why are you using reflection?

kind regards,

Ahhh okeee!!! :D
I did read it, tho I didnt understand what they ment with object
so I thought they ment object type like String and int etc :P

Well, now I sorta fixed it, the window I belive, is a copy of the real..
Because the window name doesnt change in any of the open windows, only in the one called this.f

Heres a lil bit of my code:

public class AnimationManager {
	
	public static void text(Window f, String txt,String real,int time){
		new Thread(new writeString(f).start();
	}

	
}

class writeString implements Runnable{

	Window f;
	
	public writeString(Window f){
		this.f = f;
		
	}
	
	private static void wait(int time){
		try{
			Thread.sleep(time);
		} catch(Exception e){}
	}

	@Override
	public void run(){
             changing f here wouldnt change the f that we got in the text method right?
If so, how can I change the text methods f from this method?
		}
	}

Myself, I still am finding it hard to see what you're trying to do, but I also agree with the others that reflection doesn't smell right here. Consider creating and posting a small runnable version of your problem, an SSCCE.

Well, my main idea is to have a method
that I can call that would run in an extra thread, thus not
hogging up the maincore.

What I want it to do is to change values in a class instance called
Window.

Window "f" have the parameter-String "name"

So I want to call a method text(f.name,"awsome",4000);
Using that simple method, it would add a character, one at a time
until f.name = "awsome"
This should also only take 4000 miliseconds.

That's what I want to do, and probebly I overcomplecated things eyy? :P

lawls!
Had forgot to update the repaint in the while loop :P
So the actualy picture never updated :P
