嵌套的GridBagLayout - 如何將孩子的列與父列對齊

Question

我有一個具有GridBagLayout作爲佈局的JDialog。它包含一個JPanel孩子，他也有一個GridBagLayout作爲佈局。父級包含其他字段，每個字段分爲兩列（標籤 - 編輯器）。孩子包含幾個字段，每個字段分成三列（標籤 - 編輯器 - 標籤）。我希望孩子和父母的第一列對齊在一起。這是它的外觀現在：

父相關代碼：

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); 

兒童相關代碼：

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); 

有沒有一種方法，以獲得與GridBagLayout的期望的行爲？

Answer 1

孩子包含幾個字段，每個字段分成三列（標籤 - 編輯器 - 標籤）。

您還需要使這2列面板：

1. 標籤作爲第一列
2. 面板（含編輯器和標籤）作爲第二列）
