Question

我目前正致力于改善工作项目，这需要我创建6个不同的GUI。我首先应该说我在GUI设计上非常糟糕。我曾尝试过学习Grid Bag，但确实觉得很困难。

在这个GUI中我使用BorderLayout和Flow Layout，它工作正常。我能够创建GUI并完成目标，但我不禁觉得这种方法不专业，并且如果我的其他GUI最终拥有更多JTextFields和JLabel（其中一些），将会有很多不必要的代码会）。

我想知道是否有任何布局可以减少我在这里的面板数量。我已经探索了网格布局，但我担心所有单元格大小相同。如果有人可以通过让我知道，从他们的经验，这个项目的最佳布局，并可能告诉我如何使用它，我会很感激。我已经尝试过像GridBag布局这样的布局教程，但实际上在我自己的项目中实现它有问题。

        JFrame frame = new JFrame("All File Types Selection");
        JPanel mainPanel = new JPanel(new BorderLayout());
        JPanel panelOne = new JPanel(new BorderLayout());

        frame.add(mainPanel);

        frame.setVisible(true);

        frame.setSize(630,210);

        frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

    }

}

Answer 1

我想这是一个意见，但我认为这个GUI看起来更专业。

标签和文本字段按列对齐。我使用GridBagLayout来创建GUI的表单部分。

这是代码。我将JPFnel中的JFrame代码，JPanel代码和Swing组件分组在一起，因此代码更容易理解。

我将main方法与此代码放在一起，因此我只需要粘贴一个文件。

            @Override
            public void run() {
                new AllGUI().createAllGUI();
            }
