java - 嵌套 GridBagLayout - 如何将子级的列与父级的列对齐

Question

我有一个 JDialog，其布局为 GridBagLayout。它包含一个 JPanel 子级，该子级还具有 GridBagLayout 作为布局。父级包含其他字段，每个字段分布在两列中(标签 - 编辑器)。子项包含多个字段，每个字段分布在三列中(标签 - 编辑器 - 标签)。我希望子级和父级的第一列对齐在一起。这是现在的样子:

父级相关代码:

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 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)
