これは私のGUIが今のように見えるものです:
3 つの列が均等に分散されるようにします。これを行うには、各重みを 1/3 に設定します。明らかに、それは機能していません。
フレームを作成するための私のコードは次のとおりです。
public static JPanel createLayout(int rows) {
JPanel product = new JPanel(new GridBagLayout());
String[] lables = {"School ", "Advanced #", "Novice # "};
double weight = .3333333333333;
GridBagConstraints c = new GridBagConstraints();
c.insets = new Insets(3, 3, 3, 3);
c.weightx = weight;
c.fill = GridBagConstraints.HORIZONTAL;
c.anchor = GridBagConstraints.CENTER;
c.gridy = 1;
for (int j = 0; j < lables.length; j++) {
c.gridx = j;
JLabel l = new JLabel(lables[j]);
product.add(l, c);
}
for (int i = 0; i < rows; i++) {
c.gridy++;
for (int j = 0; j < lables.length; j++) {
c.gridx = j;
JTextField f = new JTextField();
product.add(f, c);
}
}
c.gridy++;
c.gridx = 0;
c.anchor = GridBagConstraints.NORTHWEST;
c.fill = GridBagConstraints.NONE;
JPanel b = new JPanel();
JButton add = new JButton("+");
b.add(add);
JButton delete = new JButton("-");
b.add(delete);
product.add(b, c);
return product;
}
public static void main(String[] args) throws IOException {
JFrame frame = new JFrame("Debate Calculator");
JPanel debates = new JPanel();
frame.add(createLayout(5), BorderLayout.NORTH);
frame.pack();
frame.setVisible(true);
}
