我是使用 Java Swing 的新手，并且希望生成一個類似于以下內容的 GUI：
我非常接近，但有一個問題，JLabel 會像這樣推動網格設計：
我怎樣才能避免這種情況發生？我將網格放入一個 GridBagLayout 面板，將 JLabel 放入另一個 GridBag 面板（也計劃在這里放置一個 JToolbar），然后將它們添加到主框架中。
GridBagLayout tileLayout = new GridBagLayout();
GridBagConstraints tileLayoutConstraints = new GridBagConstraints();
JPanel tilePanel = new JPanel(tileLayout);
JPanel selectionPanel = new JPanel(tileLayout);
TileButton[][] tileAccessMatrix = new TileButton[4][4];
public BoardUILayer() {
setSize(1920, 1080);
buildBoardTiles();
buildResourcePrompt();
add(selectionPanel, BorderLayout.SOUTH);
add(tilePanel, BorderLayout.CENTER);
}
private void buildBoardTiles() {
for (int r = 0; r < tileAccessMatrix.length; r ) {
for (int c = 0; c < tileAccessMatrix[r].length; c ) {
TileButton temp = new TileButton(r, c);
tileAccessMatrix[r][c] = temp;
tileLayoutConstraints.ipadx = 115;
tileLayoutConstraints.ipady = 115;
tileLayoutConstraints.gridx = r;
tileLayoutConstraints.gridy = c;
temp.addActionListener(temp);
tilePanel.add(temp, tileLayoutConstraints);
}
}
}
public void buildResourcePrompt() {
final JLabel resourceTextLabel = new JLabel("What resource would you like?");
tileLayoutConstraints.ipadx = 0;
tileLayoutConstraints.ipady = 400;
tileLayoutConstraints.gridx = 50;
tileLayoutConstraints.gridy = 50;
selectionPanel.add(resourceTextLabel, tileLayoutConstraints);
}

我根據您的繪圖創建了一個 GUI。這是我在 Swing 中創建的最復雜的 GUI 之一。挑戰在于保持JButton尺寸不變。
也許 aMigLayout更適合你。
Oracle 有一個有用的教程，用 Swing 創建 GUI。跳過 Netbeans 部分。
我創建了 11 個內部JPanels來構建這個 GUI。
JFrame
main JPanel
inner JPanel
turnButton JPanel
turn JPanel
buttonGrid JPanel
resource JPanel
resourceLabel JPanel
resourceButton JPanel
manual JPanel
outerEastButton JPanel
eastButton JPanel
這是完整的可運行代碼。

您可以使用 MigLayout 和多個 JPanel 來實作。MigLayout 非常易于使用。
首先，創建一個 JPanel 并將您的組件添加到該 JPanel。其次，創建另一個 JPanel 并將其他組件添加到該 JPanel。
MigLayout 有行和列。
new MigLayout("","[][][]"/*for ex: 3 columns*/,"[][]" /*for ex 2 rows*/)
this.add(aComponent, "cell 2 1" /*for ex: that component added to third column and second row.*/);
