Angry ok this is really wierd - java painting


allright: I have a wierd java problem.

I just have to do this, which leads to another thing, then I can beta my program!

I'm getting a head of myself.
I have this hangman program, which needs to paint a scaffold/gallows and obviously the guy. Problem: when I try to paint this: nothing turned up. disapointed, I tested a LARGE rectangle, only a small square turned up.

will post the code.

if all else fails, will have to do a complete rewrite.

It looks like you are not setting the size on the canvas properly. Not all layout managers do that for you. Try calling canvas.setPreferredSize(new Dimension(<whatever>)) before you add it to the panel.

yes, I put it in the "hangman" method. Thanks.

OK: quick question: how do I add stuff to it with if statements (ie all that action event stuff) ?

Thanks, I really appreciate it.

Are you somewhat new to programming in Java?
Please don't take offense to this question - but I have a couple suggestions for you:

You should initialize your instance variables in the constructor. I know Java lets you get away with this but its good practice.
Also, you should probably have an array of JButton objects to make your code more orderly.
You might want to add some more methods instead of doing everything in the constructor - it would make your code more readable.
Also, could you not simply use: "source.setEnabled(false);" instead of checking all the letters of the alphabet in separate if's??

Anyways, just simple things like that - its mainly about readability, your programming otherwise seems fine.

Sorry if I'm presuming too much here - I don't want to offend you - just offer some suggestions about things that have helped me.

About your question, what is it exactly you are trying to "add stuff to" with if statements?

yes it is my first "real" program. The reason I'm not using arrays in my program, is partly because I have already written my program twice (read: rewritten) and don't feel like doing it again... and to have a dig at my friend, who is in the same class, uses arrays but has less idea about what his code does. heheh. will use arrays when I fully comprehend them.

You should initialize your instance variables in the constructor. I know Java lets you get away with this but its good practice.
?? what do you mean?

will try the source.setEnabled(false); then. thanks.

Please don't be concerned about stepping on my toes, I am a complete n00b and have little or no idea what I'm doing. ( )

thanks!

Ummm, I think you are missing super.paintComponent(g) in the paintComponent method. You have to stick it at the beginning.

[/B]
For example,

if you declare your JButtons globally, then do it like this:

private JButton myButton;

public hangman ( ) {
myButton = new JButton("A");
}


That way, when you actually create the hangman object (by the way, your class names should start with Capitals - I know that's picky), you actually "create" everything that has to do with that object - since the constructor is the first thing that is 'called' when you create an object, as in:
Hangman h = new Hangman();

Hope this helps.
