尝试在框架中对齐包含按钮和sudokuboards的面板

Question

我有一个java程序，可以为我创建sudokus的解决方案。然后将其打印到GUI，其中包含电路板本身，并在其下方有两个标签（当前解决方案编号和总解决方案）以及下一个按钮。这三个按钮效果很好。然而，sudokuboard让我非常头痛。我在一个方法中创建了一个方法，该方法返回一个面板，该面板包含符号框的面板，其中JLabel具有实际值。

我确实让面板打印到GUI，但它在一行并折叠。根本不是盒子！ 它开始在按钮和标签上方对齐，然后当我按下下一个按钮时，它移动到顶部，下一个sudokuboard（仍然在折叠框架中）出现在下面。 我的代码中是否有一些我忽略的东西？到目前为止，我已经尝试过GridBagLayout，FlowLayout，GridLayout和BorderLayout。都具有相同的结果。 我把代码粘贴在下面。请问是否有不明确的事情。

JFrame frame;
JPanel sudokuPanel, buttonPanel;
GridBagConstraints c;
JLabel currentSolution, counterLabel;
JButton button;

/*
 * printSolution takes a beholder-object with all the solutions, as well as
 * the board created after reading the text-file. Then it creates the GUI
 * with help from the createSudokuPanel-method. In the
 * createSudokuPanel-method I use variables which I get from the
 * solution-objects, such as all values in the solution. the rows and
 * columns-variables are information read from the text-file, telling how
 * mant rows and columns there are in each box. the convertValue-method
 * takes a number higher than 9, up to 15, and converts it into letters
 * (A...F)
