嵌套的GridBagLayout - 如何将孩子的列与父列对齐

Question

我有一个具有GridBagLayout作为布局的JDialog。它包含一个JPanel孩子，他也有一个GridBagLayout作为布局。父级包含其他字段，每个字段分为两列（标签 - 编辑器）。孩子包含几个字段，每个字段分成三列（标签 - 编辑器 - 标签）。我希望孩子和父母的第一列对齐在一起。这是它的外观现在：

父相关代码：

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); 

儿童相关代码：

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); 

有没有一种方法，以获得与GridBagLayout的期望的行为？

Answer 1

孩子包含几个字段，每个字段分成三列（标签 - 编辑器 - 标签）。

您还需要使这2列面板：

1. 标签作为第一列
2. 面板（含编辑器和标签）作为第二列）
