Thread: Accessing && Editing properties of objects in an array. Plus a few more questions.

Alright I'll put it all in the main class. Ill let you know how it goes.
And thanks for all the help so far.

You don't have to move the code.
You do need to pass a reference to JFramePlayArea to the CreatePlayField class and save it in the jFrameMain variable.

I moved everything to the main class and still nothing.

Am I not adding it correctly? Do I have to do it like the IDE automatically does in initComponents()?

Now you have gotten into a conflict with the layout manager. You have already added some components to the frame and shown it. Where should the layout manager put the new ones you want to add?

The IDE has generated lots of code to position the two components that are being shown. The new ones don't fit in with them.

Where I have specified with the points in the boxes[] array that I generated.
Would it be easier to do all of this in a separate class or in the main class?

I don't normally do weird GUI. Removing components and resetting layout in a container is not something that makes sense to me.
I really have no recommendations for you if want to do this kind of stuff.

Alright I'll repost in a more suitable board. Thanks for all of the help.
