Layout Manager and Keyboard Panel

**DOLZero** · May 22nd, 2012, 05:54 AM

I am working on a program to run a game engine. Right now I am working with a frame that has two panels in it. One is for the main display, and the other is for the keyboard controls. The problem I am having is that I want to run some subroutines that utilize the getHeight() and getLength() commands in the keyboard panel. When I try to use it, it gives results for the keyboard panel rather than the entire frame.

I have tried running different layout managers. CardLayout, GridLayout, BorderLayout, even multiple frames and have not been able to get the desired results. I had the most success with the BorderLayout, and could use fixed numbers rather than the getHeight() and getWidth() commands, but then the window would not adjust properly if resized.

I realize that my code is not optimized and looks pretty sloppy at the moment. That is not something I am worried about right now as I can always go through and clean it up once I get everything working properly.

Any help would be appreciated.

The default value for an element in an int array is 0. You only need to set the non-zero entries.

**DOLZero** · May 22nd, 2012, 07:12 AM

I am not quite sure I follow you. Are you referring to this:

		JPanel p2 = new KeyboardPanel();
		p2.setSize(0, 0);

**Norm** · May 22nd, 2012, 07:18 AM

I was referring to the massive list of assignment statements for the map array:

      int[][] map = new int[32][12];  
      map[0][0] = 1; 
      map[1][0] = 0;  //<<<<<<<<<<<<< NOT NEEDED
      map[2][0] = 0;  //<<<<<<<<<<<<< NOT NEEDED
       ....

I got it. It's old code that I haven't optimized. That doesn't help me with my current issue.

Are you asking how to get the values for component2 when executing a method in component1?

You need a reference to component2 in component1 so that the methods in component1 can use that reference to call methods in component2.

I think I figured out a way to do what you are suggesting. I created a JFrame variable to use as the general frame and made it static so I could access it anywhere in the code. It seems to work, although I need to fix some of the math in the KeyboardPanel() section of code. Sometimes it just takes a little nudge in the right direction. Thanks!

EDIT: I want to give you thanks, but I don't want to mess up that 777. That number is so pretty

Using static can be a problem sometimes. Pass a reference (use "this") to the constructor when you create the class that needs the reference and have the constructor save it in a class variable. Then methods in that class can use the reference to get to the other class.
