GroupLayoutをGridBagLayoutに変更する

Question

単純な電卓のGUIを作成していますが、私はnetbeans IDE GUIビルダーを使用しています。私はGroupLayoutのコードを理解しようとしていますが、残念ながら私はそれを取得しません。私はおそらくGridBagLayoutに変更することでより明確になり、コードを理解する上でより良い立場にあると考えました。

以下は私のコードです。誰でもGridBagLayoutに変更するのに役立つことができますか？

public class CITCalculatorGUI extends javax.swing.JFrame { 

/* Creates new frame CITCalculatorGUI */ 
public CITCalculatorGUI() { 
    initComponents(); 
} 

/* This method is called from within the constructor to 
* initialize the frame. 
*/ 

private void initComponents() {

Answer 2

はGroupLayoutとほぼ同じレイアウトを行いスニペットですが、コードのわずか10行で：

DesignGridLayout layout = new DesignGridLayout(getContentPane()); 
layout.row().grid().add(tempTextField); 
layout.row().grid().add(sevenButton, eightButton, nineButton).grid().add(plusButton, minusButton, divisionButton); 
layout.row().grid().add(fourButton, fiveButton, sixButton).grid().add(multiplication, andButton, orButton); 
layout.row().grid().add(oneButton, twoButton, threeButton).grid().add(xorButton, norButton, equalsButton); 
layout.row().grid().add(zeroButton, positiveNegativeToggle, decimalPoint).grid().empty().add(nandButton).empty(); 
layout.row().grid(1).add(base16A, base16B, base16C); 
layout.row().grid(1).add(base16D, base16E, base16F); 
layout.emptyRow(); 
layout.row().left().add(makLogo); 

これは、コードと維持するためにレイアウトを簡単にするためにDesignGridLayoutを使用しています。 GroupLayoutベースのサンプルとの視覚的な違いは、フレームを拡大するとすべてのボタンが大きくなることです（これは自分自身の好みによっては必ずしも悪くはありません）。

上記の10行を書き込むのに約5~10分かかりました。
