Java JFrame着色应该与此图片一致

我的问题有点奇怪

我希望我创建的表单（带有JFrame）的颜色应与此图片类似：

我应该使用特殊的外观和感觉吗

我应该使用特殊的外观和感觉吗

据我所知，没有这种内置的外观和感觉。然而，对于“Look&Feel”，Look指的是GUI小部件（更正式地说，是JComponents）的外观，“Feel”指的是小部件的行为方式。如果是这样的话，那么我们总是可以使Swing组件在GUI中显示为我们想要的样子

图形丰富的高级响应应用程序非常酷，从一开始就吸引用户，并以一种极度兴奋的方式紧紧抓住他们。他们让用户告诉他们的朋友有关应用程序的情况

然而，要开发图形丰富的Swing应用程序，我们必须知道如何在组件上渲染自定义图形，使它们显示为我们想要的样子（具有闪亮的颜色、美丽的纹理、移动的动画、漂亮的排版）。我们需要学习如何正确地布局组件，以便相对地排列它们。通过回答你的各种问题，我明白了你想成为一个摇摆极客。嗯：

• 首先，了解（

  JPanel、JLabel、JButton、JList、JTable、JTextPane

  等）和各种类型的事件侦听器，以及它们如何响应组件
• 第二步，了解相关信息。还有其他高级布局管理器可供使用，使生活更轻松，但首先了解标准管理器
• 第三个，了解有关回转组件和回转喷漆机制的信息。然后是关于这个问题
• 第四个，学习绘制龋齿类型的几何对象、图像渲染、纹理、梯度绘制等课程
• 五个，了解。Swing不是线程安全的，它维护单线程规则。需要对线程有很好的了解，StackOverflow几乎每天都会因Swing的线程问题而溢出
• 六个，收集这本书肮脏的富客户，当你几乎完成以上所有内容时，仔细阅读

现在，为您演示一个示例：

我已经尽力使应用程序尽可能简短。但是我已经做了一些事情来实现您所请求的GUI，如果您不知道它们是如何工作的，您不应该这样做（例如重写

paint（）

函数）。在本例中，我无法收集纹理作为您提供的图像。但是我用了一个。应用程序需要首先加载纹理图像。注意控制台。在运行应用程序之前，它将显示以下消息：

请稍候，正在加载纹理：

装载完成。开始演示

我使用：

GridBagLayout

作为主容器的窗格布局管理器。请仔细阅读代码，并阅读相应的扩展（扩展JComponent和JButton）和我为实现更好的GUI所做的绘制（对于许多评论家来说，这并没有那么好，但对于演示来说……）

您可以使用

JavaFX

，这会使您获得一些很棒的外观和感觉。 我认为，如果你想在JavaSwing中寻找一个更好的设计，它可以提供更好的外观和动画效果，那么最好使用JavaFX。 您可以参考此链接，希望这将对您有所帮助

---

L&F不是，如果您想要为工具栏（即用于NativeOS的acrulat配色方案）和按钮（最小、最大（还原）、关闭）使用不同的配色方案，则情况会有所不同，但您可以模拟此功能，所有未装饰的顶级容器都可以使用

LinearGradientPaint
