BoxLayout中的JLabel和JButton中心
[英]JLabel and JButton Center in BoxLayout
问题描述
我是Java编程的新手，无法解决我的Swing问题。 我找不到以JPanels（BoxLayout）为中心的JButton和JLabel。
这是一些照片：
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(""));

至于布局问题：有一个关于如何使用盒子布局的教程（查找组件的对齐方式以使其居中）：docs.oracle.com/javase/tutorial/uiswing/layout/box.html。
或者，您可以使用更易于使用IMO的外部布局管理器之一，例如MigLayout。
