[英]GridBagLayout Troubleshooting
因此,我決定使我的GUI看起來更好一些,並改用GridBagLayout。 以下是我要添加到面板中的對象:
choosePanel = new JPanel();
choosePanel.setLayout(new GridBagLayout());
chooseLabel = new JLabel("Choose a quarter to input data for:");
addItem(chooseLabel, 0, 0, 1, 1);
qGroup = new ButtonGroup();
q1 = new JRadioButton("Q1");
qGroup.add(q1);
q1.setSelected(true);
addItem(chooseLabel, 0, 1, 1, 1);
q2 = new JRadioButton("Q2");
qGroup.add(q2);
addItem(chooseLabel, 0, 2, 1, 1);
q3 = new JRadioButton("Q3");
qGroup.add(q3);
addItem(chooseLabel, 0, 3, 1, 1);
q4 = new JRadioButton("Q4");
qGroup.add(q4);
addItem(chooseLabel, 0, 4, 1, 1);
chooseButton = new JButton("Press to Enter Quarter");
chooseButton.addActionListener(e->{
cl.show(mainPanel, "Info");
this.setSize(330, 240);
});
chooseButton.setPreferredSize(new Dimension(200, 100));
addItem(chooseLabel, 1, 1, 1, 1);
resetButton = new JButton("Reset all previous data");
resetButton.addActionListener(e->{
});
resetButton.setPreferredSize(new Dimension(200, 100));
addItem(chooseLabel, 1, 2, 1, 1);
這是“ addItem”方法:
private void addItem(JComponent c, int x, int y, int width, int height){
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridx = x;
gbc.gridy = y;
gbc.gridwidth = width;
gbc.gridheight = height;
gbc.weightx = 100.0;
gbc.weighty = 100.0;
gbc.fill = GridBagConstraints.NONE;
choosePanel.add(c, gbc);
}
我的問題是,當我運行該程序時,顯示的只是屏幕中間的choiceLabel,而沒有其他顯示。 有人知道怎么修這個東西嗎? ......
更改
q1 = new JRadioButton("Q1");
qGroup.add(q1);
q1.setSelected(true);
addItem(chooseLabel, 0, 1, 1, 1);
q2 = new JRadioButton("Q2");
qGroup.add(q2);
addItem(chooseLabel, 0, 2, 1, 1);
q3 = new JRadioButton("Q3");
qGroup.add(q3);
addItem(chooseLabel, 0, 3, 1, 1);
q4 = new JRadioButton("Q4");
qGroup.add(q4);
addItem(chooseLabel, 0, 4, 1, 1);
至
q1 = new JRadioButton("Q1");
qGroup.add(q1);
q1.setSelected(true);
addItem(q1 , 0, 1, 1, 1);
q2 = new JRadioButton("Q2");
qGroup.add(q2);
addItem(q2, 0, 2, 1, 1);
q3 = new JRadioButton("Q3");
qGroup.add(q3);
addItem(q3, 0, 3, 1, 1);
q4 = new JRadioButton("Q4");
qGroup.add(q4);
addItem(q4, 0, 4, 1, 1);
依此類推。.您chooseLabel
都在添加chooseLabel
