控制与另一个单元格的单元格间距GridBagLayout

Question

我想要的是让第一个textField更靠近第一个jlabel，在第一个textField和第二个jlabel之间有一些空间，像这样：

JLabel：JTEXTFIELD-----（spaceeee）-------JLabel：JTEXTFIELD

但我所改变的一切都不能接近我想要的，你看：

    JLabel lblProtocolo = new JLabel("Protocolo:");
    JLabel lblDataEntrada = new JLabel("Data Entrada:");
    JTextField tfProtocolo = new JTextField(10);
    JTextField tfDataEntrada = new JTextField(10);
    JTextField soteste = new JTextField(10);
    JLabel soocupa = new JLabel();
    GridBagConstraints gbc = new GridBagConstraints();
    gbc.gridx = 0;
    gbc.gridy = 0;
    gbc.weightx = 1;
    gbc.weighty = 1;
    gbc.fill = GridBagConstraints.HORIZONTAL;
    gbc.insets = new Insets(10, 10, 10, 10);
    gbc.anchor = GridBagConstraints.NORTHWEST;
    panel2DistribuidorDistribuir.add(lblProtocolo,gbc);
gbc.gridx = 1;
    panel2DistribuidorDistribuir.add(tfProtocolo,gbc);

gbc.gridx = 2;
    panel2DistribuidorDistribuir.add(lblDataEntrada,gbc);

gbc.gridx = 3;
    panel2DistribuidorDistribuir.add(tfDataEntrada,gbc);

GBC.weightx=1；基本上是说组件希望占用100%的可用空间。

我要做的是从移除它开始...

您还可以使用GBC.insets来影响各个组件之间的距离...
