嵌套的 GridBagLayout - 如何将 child 的列与 parent 的列对齐

Question

我有一个以 GridBagLayout 作为布局的 JDialog。它包含一个 JPanel child，它也有一个 GridBagLayout 作为布局。 parent 包含其他字段，每个字段分布在两列中（标签 - 编辑器）。 child 包含几个字段，每个字段分为三列（标签 - 编辑器 - 标签）。我希望 child 和 parent 的第一列对齐在一起。这是现在的样子：

Parent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);

Child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 = 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

The child contains several fields which are disposed in three columns each (label - editor - label).

您还需要将其设为 2 栏面板：

标签为第一列
面板（包含编辑器和标签）作为第二列）
