RadioButton 和 CheckBox 未在自定义外观中显示

Question

我正在为一家公司创建一个定制的外观和感觉，作为我毕业的最后一个实习船。我已经在这部分卡了几天了，我和我的同事似乎无法修复它。

我正在尝试为外观创建一个自定义单选按钮和一个复选框。现在，当我想将库存显示到屏幕/ JFrame 时，它​​不会显示。

一旦我激活我的外观和感觉，复选框和单选按钮就会消失。但它们的标签确实显示在屏幕上。当我在外观之外创建复选框/收音机或为它们提供灵气外观时，它会显示。所以不知何故，我的外观和感觉正在破坏事物。任何人都可以帮忙吗？

这是我的单选按钮代码；

public class MyRadioBut extends BasicRadioButtonUI {


    public MyRadioBut()
    {
        super();
    }

    public static ComponentUI createUI(JComponent c) {
        return new MyRadioBut();
    }

    @Override
    public void installUI(final JComponent c) {
        super.installUI(c);
    }

    public static MyRadioBut createRadio()
    { 
        MyRadioBut radio = new MyRadioBut();

        return radio;
    }
    private boolean defaults_initialized = false;
    @Override
    public void installDefaults(AbstractButton b) {  
        super.installDefaults(b);

    }
}

复选框的代码是相同的。

        //   UIManager.put(MyLookAndFeel.UI_CLASS_ID,  MyButton.class.getName());
        table.putDefaults(uiDefaults);
    }
}

IACPackage 是我自己的包，我在所有组件中都使用它。

希望你们中的一个有想法。

我有一个测试 gui，我可以在上面测试外观：我像这样创建复选框和收音机；

JCheckBox CBox = new JCheckBox("Checkbox"); JRadioButton Radio = new JRadioButton("Radio");

它确实显示字符串但不显示图标。

Answer 1

自己修好了。

Icon defaultIcon;  
defaultIcon = UIManager.getIcon("CheckBox.icon");
UIManager.put("CheckBox.icon", defaultIcon);

我使用它从 UI 管理器中获取默认图标，然后使用 put 语句将其放回原处。相当愚蠢的解决方案，但它有效！
