嵌套GridBagLayout -如何使子列与父列对齐

Question

我有一个JDialog，它有一个GridBagLayout作为布局。它包含一个JPanel子元素，它也有一个GridBagLayout作为布局。父字段包含其他字段，它们分别在两列(标签编辑器)中被释放。子字段包含几个字段，每个字段以三列(标签-编辑器-标签)进行处理。我希望子列和父列都对齐。现在的情况如下：

家长相关代码：

GridBagConstraints contrainte = new GridBagConstraints();
Insets insetsLabel = new Insets(0, 0, 0, 0);
Insets insetsChampsEdit = new Insets(0, 10, 0, 0);

contrainte.ipady = 10;
contrainte.gridx = 0;
contrainte.gridy = 1;
contrainte.fill = GridBagConstraints.HORIZONTAL;
contrainte.gridwidth = 1;
this.add(this.m_lblPremierDepart, contrainte);

contrainte.gridx = 1;
contrainte.insets = insetsChampsEdit;
this.add(this.m_timePicker, contrainte);

contrainte.gridx = 0;
contrainte.gridy = 2;
contrainte.insets = insetsLabel; // reset insets
contrainte.gridwidth = 3;
this.add(this.m_panneauDistribution, contrainte);

contrainte.gridy = 3;
contrainte.gridwidth = 1;
this.add(this.m_lblNbMaxVehicules, contrainte);

contrainte.gridx = 1;
contrainte.insets = insetsChampsEdit;
this.add(this.m_spinNbMaxVehicules, contrainte);

contrainte.gridx = 0;

contrainte.insets = insetsLabel; // reset insets
this.add(this.m_lblMoyen, contrainte);

contrainte.gridx = 1;
contrainte.insets = insetsChampsEdit;
this.add(this.m_spinMoyen, contrainte);

contrainte.gridx = 2;
this.add(new JLabel("minute(s)"), contrainte);

contrainte.gridx = 0;
contrainte.gridy = 2;
contrainte.insets = insetsLabel; // reset insets
this.add(this.m_lblPlusGrand, contrainte);

contrainte.gridx = 1;
contrainte.insets = insetsChampsEdit;
this.add(this.m_spinPlusGrand, contrainte);

contrainte.gridx = 2;
this.add(new JLabel("minute(s)"), contrainte);

是否有一种方法可以通过GridBagLayout获得所需的行为？

Answer 1

子字段包含几个字段，每个字段以三列(标签-编辑器-标签)进行处理。

您还需要将其设置为2列面板：

1. 标签为第一列
2. 面板(包含编辑器和标签)作为第二列)
