java - 如何使用 Swing 在 JFrame 上应用 JTatto 主题

Question

我正在尝试在我的挥杆项目中应用 JTatto 外观和感觉。

该主题已应用于某些表单，但在其他表单上，控件无法正常工作。它们相互重叠。

要应用主题，我使用以下代码

try
{
  String lookandfeel="com.jtattoo.plaf.smart.SmartLookAndFeel";
  UIManager.setLookAndFeel(lookandfeel);
 }
 catch(Exception ex)
{
 ex.printStackTrace();
}

Answer 1

• 按我的预期工作

• L&F 必须是

  1. 在创建 GUI 之前初始化

  2. 对于运行时的更改，通过调用SwingUtilities.updateComponentTreeUI(Component c)应用于所有顶级容器，其中更简单的是== 局部变量 for ，否则您必须迭代并将此外观分别应用于每个 JComponent，应用于所有在当前组件树中Component cTop-Level Container
