Java gridbaglayout調整

這是此問題的擴展：Java gridbaglayout problems。由於panel1的寬度溢出，Panel1與panel2重疊。但是，如果我刪除了gc.gridwidth = 2，它將正確對齊panel2，但它也會將組合框移到其右側的原始位置。我一直在玩弄不同的gridbaglayout屬性，但不能像我想要的那樣對齊它。Java gridbaglayout調整

繼承人我的代碼：

public void createGUI() 
{ 
    main_panel = new JPanel(); 
    main_panel.setLayout(new GridBagLayout()); 
    GridBagConstraints gc = new GridBagConstraints(); 

    gc.fill = GridBagConstraints.HORIZONTAL; 
    gc.gridx = 0; 
    gc.gridy = 0; 
    gc.insets = new Insets(5, 0, 10, 0); 
    main_panel.add(label, gc); 

    gc.fill = GridBagConstraints.HORIZONTAL; 
    gc.gridx = 1; 
    gc.gridy = 0; 
    gc.insets = new Insets(5, 0, 10, 0); 
    main_panel.add(band_combobox, gc); 

    gc.fill = GridBagConstraints.HORIZONTAL; 
    gc.gridx = 0; 
    gc.gridy = 1; 
    gc.gridwidth = 2; 
    gc.insets = new Insets(0, 0, 10, 0); 
    main_panel.add(panel1, gc); 

    gc.fill = GridBagConstraints.HORIZONTAL; 
    gc.gridx = 1; 
    gc.gridy = 1; 
    gc.gridwidth = 2; 
    gc.insets = new Insets(0, 0, 10, 0); 
    main_panel.add(panel2, gc); 

    gc.fill = GridBagConstraints.HORIZONTAL; 
    gc.gridx = 0;

    gc.gridwidth = 2;

    main_panel.add(panel3, gc); 
}

GBC是基於第1行創建 – mKorbel

把標籤和組合框與流佈局一個單獨的面板和cooordinates放置在頂部。 – Marco

@mKorbel謝謝。我將panel2的gridx設置爲3，並將panel2正確對齊，但標籤和combox沒有居中。 – user1352609

不要害怕使用複合佈局來實現您的需求。您的標籤和組合框想要「浮動」在最上面一排。這將是一個難以實現它自己的一個GridBagLayout的事情，但通過將它們添加到另一個容器中，用不同的佈局管理器，它是可以實現的......

enter image description here

當您更改組件gridWidth或gridHeight這將讓他們「流動」到其他行和列，這意味着他們可以坐在上面或下面是佔用空間，這取決於加入時，他們對組件...

此外，檢查出的weight性質。

試試這個：

public void createGUI() 
{ 
    main_panel = new JPanel(); 
    main_panel.setLayout(new GridBagLayout()); 
    GridBagConstraints gc = new GridBagConstraints(); 

    gc.fill = GridBagConstraints.HORIZONTAL; 
    gc.gridx = 0; 
    gc.gridy = 0; 
    gc.insets = new Insets(5, 0, 10, 0); 
    main_panel.add(label, gc); 

    gc.fill = GridBagConstraints.HORIZONTAL; 
    gc.gridx = 1; 
    gc.gridy = 0; 
    gc.insets = new Insets(5, 0, 10, 0); 
    main_panel.add(band_combobox, gc); 

    gc.fill = GridBagConstraints.HORIZONTAL; 
    gc.gridx = 0; 
    gc.gridy = 1; 
    gc.gridwidth = 1; 
gc.weightx = 1; 
gc.weighty = 1; 
    gc.insets = new Insets(0, 0, 10, 0); 
    main_panel.add(panel1, gc); 

    gc.fill = GridBagConstraints.HORIZONTAL; 
    gc.gridx = 1; 
    gc.gridy = 1; 
    gc.gridwidth = 1; 
gc.weightx = 1; 
gc.weighty = 1; 
    gc.insets = new Insets(0, 0, 10, 0); 
    main_panel.add(panel2, gc); 

    gc.fill = GridBagConstraints.BOTH; 
    gc.gridx = 0; 
    gc.gridy = 2; 
gc.weightx = 1; 
gc.weighty = 1; 
    gc.gridwidth = 2; 
    gc.insets = new Insets(0, 0, 10, 0); 
    main_panel.add(panel3, gc); 
}

你沒有設定重量，而你的寬度設置有點不妥。

也把樂隊的標籤和組合在一個JPanel，並將其寬度設置爲兩個，並將其添加到頂部。這看起來好多了。

另請參閱我的GridBagLayout教程（在我的博客中，在我的配置文件中）獲取更多幫助。

樂隊目錄標籤，組合框，會員小組和CD列表面板應分配gridwidth = 1具有讀取和添加CD面板gridwith = 2 。

GBC來創建列需要座標在第一行，則創建矩陣爲整個容器，緩和的坡度是必要的調整大小無閃爍
肯定的是可能幾乎創造這個GBC矩陣而不是將無形的JComponents（JLabel在這種情況下添加邊框）添加到合成器中，也許爲什麼要打擾，
這是關於使用GBC的AbsoluteLayout，另一種方法是使用隱形JC omponents
