允许用户在图像上手写标记-Java、Swing

我正在使用Java Swing开发一个应用程序。它将主要用于研究用于医学目的的波形图和五角星图。人们希望用户能在图像的顶部留下笔记（大概是像窗户油漆中使用的铅笔一样的东西）

请记住，每次用户加载图像时，以下鼠标运动监听器都会附加到图像上（为了使图像可用性方面的原因可以拖动）：

到目前为止，我甚至无法接近一种实现它的方法，我也无法在互联网上找到任何关于这个问题的参考资料。任何帮助（即使是粗略的想法）都将不胜感激。提前谢谢

我试过你要的

DragMouseListener

但觉得很不舒服，所以用了

JInternal框架

效果很好（但你仍然可以在JInternal框架内拖动图像，因为我实现了你的要求）。我使用了

绝地窗格

（您可以添加手写的东西，如果您愿意的话，但这将是一个混乱）使用可访问的父JScrollPane，这样您就可以键入您想要多少

您可以轻松拖动内部框架：

注意：我已经为此使用了NetBeans GUI Builder，并建议您也使用任何GUI Builder 打字很容易

代码如下：

请参阅@mKorbel和@trashgod的帖子回复，以使内部框架最小化/最大化并调整大小。答案很好。

您希望图像与文本永久更新，还是希望图像与文本关联…例如，可以根据需要加载和更新的层？您希望文本“手写”吗或者提供用户在图像上键入文本的功能就足够了吗？为回复干杯。保存图像（包括自定义注释）的功能是可取的。键入文本不起作用，但一些固定的解决方案可能就足够了（例如，提供一个圆圈工具，允许用户旋转示波图的峰值）引用的示例说明了几种基本的对象绘制技术。“示波图与五角星图”嗯？虽然第一个让人联想到医务人员的图像，但第二个让我联想到女巫。--我倾向于存储图像和任何相关文本在一个Zip文件中，以便以后可以重建、编辑和调整。当然，提供“导出到标题PNG”-但要明确用户正在从中丢失一些东西。作为旁白。你的问题是什么？希望这个关于的答案在某种意义上可能会有所帮助。非常感谢你遇到所有这些麻烦并给我是代码。使用jInternalFrame似乎是一个更具吸引力和鲁棒性的解决方案。我决定采用它，巧合的是，我也使用了NetBeans GUI Builder。但是，我无法使内部框架可调整大小、最小化和拖动。对于前两个，我使用了它们的属性选项卡中提供的相应复选框，但它们不正确响应任何更改。尤其是调整大小对请求的功能至关重要。有什么想法吗？是的，我也有这个问题。因此这是一个编码问题。任何方法都可以遵循，如果你找不到解决方案，请告诉我。我会尽力帮你。或者，如果你发现了，请更新它……）和
