Java 将GroupLayout更改为GridBagLayout
我正在创建一个简单的计算器GUI，我一直在使用netbeans IDE GUI builder。我一直在试图理解Java 将GroupLayout更改为GridBagLayout,java,swing,user-interface,layout,Java,Swing,User Interface,Layout,我正在创建一个简单的计算器GUI，我一直在使用netbeans IDE GUI builder。我一直在试图理解GroupLayout代码，但不幸的是，我没有理解它。我想，如果改为GridBagLayout，可能会更清晰，我也能更好地理解代码 下面是我的代码。有人能帮我把它改成GridBagLayout public class CITCalculatorGUI extends javax.swing.JFrame { /* Creates new frame CITCalculatorGUI

请看这里：。它在面板中使用GridLayout，可能会对您有所帮助。这里有一个代码片段，它的布局几乎与
GroupLayoutDesignGridLayout layout = new DesignGridLayout(getContentPane());
layout.row().grid().add(tempTextField);
layout.row().grid().add(sevenButton, eightButton, nineButton).grid().add(plusButton, minusButton, divisionButton);
layout.row().grid().add(fourButton, fiveButton, sixButton).grid().add(multiplication, andButton, orButton);
layout.row().grid().add(oneButton, twoButton, threeButton).grid().add(xorButton, norButton, equalsButton);
layout.row().grid().add(zeroButton, positiveNegativeToggle, decimalPoint).grid().empty().add(nandButton).empty();
layout.row().grid(1).add(base16A, base16B, base16C);
layout.row().grid(1).add(base16D, base16E, base16F);
layout.emptyRow();
layout.row().left().add(makLogo);
GroupLayout编辑：添加两行额外的代码以在底部添加徽标。+1该代码还演示了相互嵌套布局的概念（网格布局
位于边界布局）。这里是另一个。@Wassma：“我想也许换成GridBagLayout
会更清晰”？！？是什么让你认为改用GBL可以达到这个目的？这似乎与我在GBL方面的所有经验背道而驰。即使是提倡GBL的人也通常使用助手方法来定义组件的布局约束。您建议使用哪种布局管理器查看我对嵌套布局的评论（重点是s）。如果您还发布了您想要实现的屏幕截图（或模型），您的问题将更有意义。有几十个布局管理器，您可以根据自己的需求选择其中一个（或一组nexted布局，尽管我通常不推荐）。呵呵，这个问题完美地说明了为什么要避免GUI构建器；-）我只是看到我忘记了徽标（我无法在原始面板中看到它，因为我没有它的图像文件）。不确定它应该放在哪里（最后一行，但它是否居中？@Wassma：对于创建涉及的图像，我建议热链接到互联网上可用的图像（例如，我的任何图像），或者在源中生成图像，如图所示（红色/橙色渐变）。当然，这个问题也可以用绘画或ASCII艺术来描述。
