我正在尝试制作一款看起来像这样的游戏:
我正在尝试为此找到最合适的布局设计。我尝试使用 gridbag 布局，但有一些组件未正确添加。这是我的代码:
//Gridbag for the whole frame
GridBagLayout gridbag = new GridBagLayout();
GridBagConstraints constraints = new GridBagConstraints();
this.setLayout(gridbag);
constraints.fill = GridBagConstraints.BOTH;
constraints.insets = new Insets(10, 10, 10, 10);
constraints.weightx = 0.5;
//Top left panel
pnlHP = new JPanel();
pnlHP.setBackground(new Color (75, 55, 28));
gridbag.setConstraints(pnlHP, constraints);
this.add(pnlHP);
GridBagLayout gridbagHP = new GridBagLayout();
GridBagConstraints constraintsHP = new GridBagConstraints();
pnlHP.setLayout(gridbagHP);
constraintsHP.fill = GridBagConstraints.BOTH;
constraintsHP.insets = new Insets(10, 10, 10, 10);
constraintsHP.weightx = 1.0;
lblHPTitle = new JLabel();
lblHPTitle.setText("HP");
lblHPTitle.setForeground(Color.WHITE);
lblHPTitle.setFont(new Font("Arial", Font.PLAIN, 60));
gridbagHP.setConstraints(lblHPTitle, constraintsHP);
pnlHP.add(lblHPTitle);
lblHP = new JLabel();
lblHP.setText("asdf");
lblHP.setForeground(Color.WHITE);
lblHP.setFont(new Font("Arial", Font.PLAIN, 20));
lblHP.setHorizontalAlignment(SwingConstants.RIGHT);
constraintsHP.gridwidth = GridBagConstraints.REMAINDER;
gridbagHP.setConstraints(lblHP, constraintsHP);
pnlHP.add(lblHP);
pgbHP = new JProgressBar();
pgbHP.setBackground(new Color (75, 55, 28));
pgbHP.setValue(25);
constraintsHP.weightx = 0.0;
gridbagHP.setConstraints(pgbHP, constraintsHP);
pnlHP.add(pgbHP);
//Top center part
btnGo = new JButton();
btnGo.setBackground(new Color (126, 72, 28));
btnGo.setText("Start Adventure!");
btnGo.setForeground(Color.WHITE);
btnGo.setFont(new Font("Arial", Font.PLAIN, 42));
gridbag.setConstraints(btnGo, constraints);
this.add(btnGo);
//Top right panel
pnlMPSP = new JPanel();
pnlMPSP.setBackground(new Color (75, 55, 28));
constraints.gridwidth = GridBagConstraints.REMAINDER;
gridbag.setConstraints(pnlMPSP, constraints);
this.add(pnlMPSP);
GridBagLayout gridbagMPSP = new GridBagLayout();
GridBagConstraints constraintsMPSP = new GridBagConstraints();
pnlMPSP.setLayout(gridbagMPSP);
constraintsMPSP.fill = GridBagConstraints.BOTH;
constraintsMPSP.insets = new Insets(10, 10, 10, 10);
constraintsMPSP.weightx = 1.0;
lblMPSP = new JLabel();
lblMPSP.setText("asdf");
lblMPSP.setForeground(Color.WHITE);
lblMPSP.setFont(new Font("Arial", Font.PLAIN, 20));
gridbagMPSP.setConstraints(lblMPSP, constraintsMPSP);
pnlMPSP.add(lblMPSP);
lblMPSPTitle = new JLabel();
lblMPSPTitle.setText("MP");
lblMPSPTitle.setForeground(Color.WHITE);
lblMPSPTitle.setFont(new Font("Arial", Font.PLAIN, 60));
lblMPSPTitle.setHorizontalAlignment(SwingConstants.RIGHT);
constraintsMPSP.gridwidth = GridBagConstraints.REMAINDER;
gridbagMPSP.setConstraints(lblMPSPTitle, constraintsMPSP);
pnlMPSP.add(lblMPSPTitle);
pgbMPSP = new JProgressBar();
pgbMPSP.setBackground(new Color (0, 0, 255));
pgbMPSP.setValue(25);
constraintsMPSP.weightx = 0.0;
gridbagMPSP.setConstraints(pgbMPSP, constraintsMPSP);
pnlMPSP.add(pgbMPSP);
//Middle Left
lblNotifications = new JLabel();
lblNotifications.setText("<html>N<br>o<br>t<br>i<br>f<br>i<br>c<br>a<br>t<br>i<br>o<br>n<br>s</html>");
lblNotifications.setFont(new Font("Arial", Font.PLAIN, 20));
lblNotifications.setBackground(Color.WHITE);
gridbag.setConstraints(lblNotifications, constraints);
this.add(lblNotifications);
//Middle Center
txtNotifCenter = new JTextPane();
txtNotifCenter.setBackground(new Color (205, 160, 96));
txtNotifCenter.setEnabled(false);
txtNotifCenter.setDisabledTextColor(Color.black);
scpNotifCenter = new JScrollPane(txtNotifCenter);
scpNotifCenter.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED);
gridbag.setConstraints(scpNotifCenter, constraints);
this.add(scpNotifCenter);
//Middle Right
txtXPInfo = new JTextPane();
txtXPInfo.setBackground(new Color (205, 160, 96));
txtXPInfo.setEnabled(false);
txtXPInfo.setDisabledTextColor(Color.black);
scpXPInfo = new JScrollPane(txtXPInfo);
scpXPInfo.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED);
constraints.gridwidth = GridBagConstraints.REMAINDER;
gridbag.setConstraints(scpXPInfo, constraints);
this.add(scpXPInfo);
//I haven't made the bottom part yet
this.pack();
如果运行此命令，lblNotifications 和 txtNotifCenter(或 scpNotifCenter)似乎具有相同的宽度。我想把它做成图中的样子。我是否应该使用其他布局，或者我只是以错误的方式使用 gridbag 布局？预先感谢您!
最佳答案
GridBagLayout 非常难用，只有那些贪图惩罚的人才会尝试使用它。它实际上最初是供 GUI 构建者使用的，而不是手动编码的。
您应该使用嵌套布局。您实际上有一个非常标准的布局。对于主窗口，请使用 BorderLayout(这是所有顶级容器(如 JFrame)的默认布局)。
您的 HP、Start Adventure 和 MP 将位于使用 X_AXIS BoxLayout 的 JPanel 中(JPanel 默认情况下使用 FlowLayout，因此您必须将其设置为 BoxLayout)。该 JPanel 将位于 BorderLayout 的北部位置。
您的两个通知文本区域可能最好放在 JSplitPane 中(一个文本区域位于左侧，另一个文本区域位于右侧)，然后将分割 Pane 放在 BorderLayout 的中心。
然后您的 CharMode、Level 和 Logout 将位于另一个使用 X_AXIS BoxLayout 的 JPanel 中。该 JPanel 将位于 BorderLayout 的南位置。
