KeyListener doesnt work some times.

[Addez]

Hello
Because people did not realise that I NEED to learn to hack
(to prevent slaughter of christians in a couple of years)
and instread decided to becoming jerks,I decided
to do something else. A 2d simple game.

now, for no reason what so ever!
The key listener stops working! :(
I added it to the JFrame AND to the JPanel contaning my
drawings of sqares but now it stopped working AGAIN!!


First it works. you can drive you lil helicopter, but then suddenly during
one my my debugs, it stops working.
No input is gatherd whatso ever!
Why?

Hard to tell without more info about the code and the OS it is running on.
Does the component with the listener have the focus?

first of all what has religion got to do with code. second of all where is your example code, third of all what?

That is a preposterous argument; if it weren't so ludicrous I'd report your topic.

Yes I think so.
I got a JLabel inside a JFrame and thats all.
When I click it, one of them should get the focus right?

From the API documentation of the JLabel class:

A display area for a short text string or an image, or both. A label does not react to input events. As a result, it cannot get the keyboard focus. A label can, however, display a keyboard alternative as a convenience for a nearby component that has a keyboard alternative but can't display it.

kind regards,

The posts above certainly suggests that we be observant.

[Addez]

Dear Josh,
I realize that you are talking with eloquence in order to attain credibility
that you are of superior kind when arguing over these mathers.
I will therefore reply in the same elocutio.

Allow me to inform sir that I have not failed to furfilled every rules
applied to this specific page. Rather I came with a non-debateable
statement that the end of time is certainly approaching.


As for my real question:
Soo..
I got a JFrame, yet the keylistener stops working at random points
when I debug..
Hum.. Should I use something else instead of keylistener?

[Norm]

Could you post a small program that compiles and executes and demonstrates your problem?

[Addez]

Found out what it was.
I forgot to add:
@Override
thingy over my methods.. -.-

[Tolls]

Sometimes this place really throws up some surprises...:)

[Norm]

But that doesn't explain the "sometimes" aspect of the problem. Either the method was an override or it wasn't

[Addez]

Idk why, but it stopped it.
It works always now, as before only worked 50% of the time.

[Fubarable]

As far as I know, @Override will only effect the compilability of the code, not the behavior of the code.

[Norm]

AFAIK Computers are very consistent. There has to be something else about your code that allowed the "sometimes" aspect of the problem.

[Tolls]

As far as I know, @Override will only effect the compilability of the code, not the behavior of the code.

@Override doesn't stop it from compiling unless it is applied to a method that doesn't exist in a superclass.
