哪种java布局适合我的布局

我正在努力制作一个类似这样的游戏:Layout Design

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();

如果运行此选项,则lblNotifications和txtNotifCenter(或scpNotifCenter)似乎具有相同的宽度。我想在照片中做到这一点。我应该使用另一种布局,还是我只是以错误的方式使用网格布局?提前谢谢!

不确定屏幕的哪些部分是组件而哪些不是(例如hp显示一个组件或一组组件?)但是GridBagLayout当然可以做你想要的。

关键是不要尝试使用一个GridBagLayout来完成所有操作,因为这样一切都需要在网格中排成一行。

而是将屏幕分成三行。在布局上使用来排列三行(例如BoxLayout),然后在每行中使用单独的布局管理器(例如GridBagLayout)来布置该行中的组件。

GridBagLayout非常难以使用,只有那些受到惩罚的人才会尝试使用它。它实际上最初是由GUI构建器使用,而不是手工编码。

您应该使用嵌套布局。你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(JPanels默认使用FlowLayout,因此您必须将其设置为BoxLayout)。 JPanel将进入BorderLayout的NORTH位置。

您的两个通知文本区域可能在JSplitPane中最佳(左侧有一个文本区域,右侧有另一个文本区域),然后将分割窗格放在BorderLayout的CENTER中。

然后你的CharMode,Level和Logout将使用X_AXIS BoxLayout进入另一个JPanel。 JPanel将进入BorderLayout的南部位置。
