【问题描述】:
我是 Java 编程新手,无法处理我的 Swing 问题。我无法让 JButtons 和 JLabels 在 JPanels(BoxLayout) 中居中。
这里有一些照片:
代码:
PlayerLabel.setHorizontalTextPosition(JLabel.CENTER);
PlayerLabel.setVerticalTextPosition(JLabel.BOTTOM);
PlayerLabel.setText("Player Level: " + CarMain.main[5]);
AccessoriesLVL1Label.setHorizontalTextPosition(JLabel.CENTER);
AccessoriesLVL1Label.setVerticalTextPosition(JLabel.BOTTOM);
AccessoriesLVL1Label.setText("<html>Accessories LVL 1<br>" + "Count: " + Part.parts[1]);
JButton jbtnSellAccessoriesLv1 = new JButton("Sell");
jbtnSellAccessoriesLv1.addActionListener(this);
这就是我制作 Jlabel 的地方:
//升级面板
GridLayout UpgradesLayout = new GridLayout(3,3);
JPanel UpgradesPanel = new JPanel();
UpgradesPanel.setLayout(UpgradesLayout);
JPanel UpgradesPanelSub = new JPanel();
UpgradesPanelSub.setLayout(new BoxLayout(UpgradesPanelSub, BoxLayout.PAGE_AXIS));
UpgradesPanelSub.setBorder(BorderFactory.createCompoundBorder(raisedbevel, loweredbevel));
JPanel UpgradesPanelSub2 = new JPanel();
UpgradesPanelSub2.setLayout(new BoxLayout(UpgradesPanelSub2, BoxLayout.PAGE_AXIS));
UpgradesPanelSub2.setBorder(BorderFactory.createCompoundBorder(raisedbevel, loweredbevel));
JPanel UpgradesPanelSub3 = new JPanel();
UpgradesPanelSub3.setLayout(new BoxLayout(UpgradesPanelSub3, BoxLayout.PAGE_AXIS));
UpgradesPanelSub3.setBorder(BorderFactory.createCompoundBorder(raisedbevel, loweredbevel));
UpgradesPanelSub.add(Labels.PlayerLabel);
UpgradesPanelSub.add(jbtnUpgradeLevel);
UpgradesPanelSub2.add(Labels.GarageLabel);
UpgradesPanelSub2.add(jbtnUpgradeGarageLevel);
UpgradesPanelSub3.add(Labels.BoxesLVLLabel);
UpgradesPanelSub3.add(jbtnUpgradeBoxesLevel);
UpgradesPanel.add(new JLabel(""));
UpgradesPanel.add(new JLabel(""));
UpgradesPanel.add(new JLabel(""));
UpgradesPanel.add(UpgradesPanelSub);
UpgradesPanel.add(UpgradesPanelSub2);
UpgradesPanel.add(UpgradesPanelSub3);
UpgradesPanel.add(new JLabel(""));
UpgradesPanel.add(new JLabel(""));
UpgradesPanel.add(new JLabel(""));
【问题讨论】:
-
为减少混淆,我建议您查看 Java 编码约定,尤其是它建议变量和字段名称应以小写字符开头的部分(例如
upgradesPanel)。 -
@Thomas 是的,对此感到抱歉.. 我已经阅读了它,但在这一刻,我不想重写所有 ~10'000 行,并检查一下,小写字母,在哪里大,我稍后再做。不过谢谢你的建议。

@Thomas,谢谢我找到了。做出答案,我会检查它是否正确。
