嵌套GridBagLayout-如何将子列与父列对齐

Question

我有一个将GridBagLayout作为布局的JDialog。它包含一个JPanel子级，该子级也有一个GridBagLayout作为布局。父级包含其他字段，每个字段设置在两列中（标签-编辑器）。子级包含几个字段，每个字段设置在三列中（标签-编辑器-标签）。我希望子级和父级的第一列对齐在一起。这是它现在的样子：

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);

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 = 0;
contrainte.fill = GridBagConstraints.HORIZONTAL;
this.add(this.m_lblPlusPetit, contrainte);

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

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

contrainte.gridx = 0;
contrainte.gridy = 1;
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);

有没有办法通过GridBagLayout获得所需的行为？

Answer 1

子项包含几个字段，每个字段分为三列（标签-编辑器-标签）。

您还需要将其设置为2列面板：

1. 标签作为第一列
2. 面板（包含编辑器和标签）作为第二列）
