GridBagLayout-forcing content left.

[Mapisto]

Before troubling you, I've searched information about this and found some1 else who had the same problem.

One of the guys who answered him proposed a solution that worked (I've tried it myself).

The thing is, I couldn't understand what exactly the change in the code did to make it work!

here's the link:
gridBagLayout anchor ... wanna move all components to top left

Take a look at reply #12 - the guy added "d" after declaring the c.weight=1

Without the "d" it just won't work no matter what else I've tried, the content stayed in the middle.

So what exactly this 'd' stands for? how does it help ?

Thanks :)

Um, I am not sure yet, but I can tell you that, if you place a 'd' character after a number in Java, it will cast it as a double. Or something similar to that. For example:

 double number = 1d;

if you do

 int number = 1d;

you get an error saying lose of precision because the number is a double and you trying to fit it into an integer.
Same goes with floats.

 float number = 1f;

Maybe, making the number a double precision primitive type makes the weight work.

Ye,
I thought it maybe has something to do with that, because we use these letters for "printf".

But now I've tried just writing 1 without 'd' and it worked! when I write 0 is doesn't work.

That's an entirely different kettle of fish. Don't confuse them just because the same letter is used.

Thanks DarrylBurke. I have always wondered what those letters were called.
