Java Components doing whatever they want

[Pan Niko]

Hello,

I have really stuck at this point. I have the code below:

mainBoard = new JPanel(new BorderLayout());
board = new JPanel(new BorderLayout());

for(int i=0; i<4; i++){
			
			if(i==0){
				JPanel arrowPanel = new JPanel();
				arrowPanel.setLayout(new FlowLayout());
				for(int k =0; k<4; k++){
					arrows[i][k] = new JCoordButton(up);
					arrows[i][k].setPreferredSize(new Dimension(40,40));
					arrowPanel.add(arrows[i][k]);
				}
				board.add(arrowPanel, BorderLayout.NORTH);
			}
			else if(i==1){
				JPanel	arrowPanel = new JPanel();
				arrowPanel.setLayout(new FlowLayout());
				for(int k =0; k<4; k++){
					arrows[i][k] = new JCoordButton(right);
					arrows[i][k].setPreferredSize(new Dimension(40,40));
					arrowPanel.add(arrows[i][k]);
				}
				board.add(arrowPanel, BorderLayout.PAGE_END);
			}
			else if(i==2){
				JPanel	arrowPanel = new JPanel();
				arrowPanel.setLayout(new FlowLayout());
				for(int k =0; k<4; k++){
					arrows[i][k] = new JCoordButton(down);
					arrows[i][k].setPreferredSize(new Dimension(40,40));
					arrowPanel.add(arrows[i][k]);
				}
				board.add(arrowPanel, BorderLayout.SOUTH);
			}
			else if(i==3){
				JPanel arrowPanel = new JPanel();
				arrowPanel.setLayout(new FlowLayout());
				for(int k =0; k<4; k++){
					arrows[i][k] = new JCoordButton(left);
					arrows[i][k].setPreferredSize(new Dimension(40,40));
					arrowPanel.add(arrows[i][k]);
				}
				board.add(arrowPanel, BorderLayout.PAGE_START);
			}
		}

board.add(colourBoard, BorderLayout.CENTER);
mainBoard.add(board, BorderLayout.CENTER);

The output is as shown below :

You can imagine from my code that is not the result I want! So, what I'm doing wrong? Any idea?

Thank you

If there are separate code blocks for all values of "i" anyway, then there's no point in having the loop at all.

I can't tell what you're trying to accomplish, though; can you describe it in words?

[Campbell Ritchie]

The Components are not doing “what they want”, but what they always do: what you tell them. You said to add the panel four times, and it added the panel four times.

[Pan Niko]

Yes but, I'm creating new Panel each time and also has different position for each condition(North, South, Page Start, Page End). Also, I have right and left be Page Start and Page End, then why place them North and South ? :S Really weird

Well, no we can't really. If that's the code that's giving you the output, then how can we expect it to do anything else than what it's doing?

Why don't you tell us what you want?

Hello,

Thanks for responses. With code above wanted to add different arrows around a board. That's why I was using North, South, Page End and Start. Figured out how to do it and are simply two things. First, use West and East instead of Page End - Start and second panel's layout to be BoxLayout(), with Y_Axis or X_Axis.

Thank you, again
