JavaFX新的自定义弹出窗口
我正在搜索JavaFX中弹出窗口的示例。 我有一个JavaFX应用程序,我需要一个弹出窗口。这个弹出窗口需要一些复杂的输入,我需要处理和检查这些输入,然后返回主应用程序/窗口 现在的问题是我在任何地方都找不到一个例子,如何在一个JavaFX控制器类中调用现在的JavaFX弹出窗口?我只找到了examle如何创建对话框弹出窗口,但我找不到基于JavaFX的新弹出窗口示例(我看到了一个解决方案,其中有两个窗口并行,但我只需要在需要时创建一个)JavaFX新的自定义弹出窗口,java,javafx,dialog,Java,Javafx,Dialog,我正在搜索JavaFX中弹出窗口的示例。 我有一个JavaFX应用程序,我需要一个弹出窗口。这个弹出窗口需要一些复杂的输入,我需要处理和检查这些输入,然后返回主应用程序/窗口 现在的问题是我在任何地方都找不到一个例子,如何在一个JavaFX控制器类中调用现在的JavaFX弹出窗口?我只找到了examle如何创建对话框弹出窗口,但我找不到基于JavaFX的新弹出窗口示例(我看到了一个解决方案,其中有两个窗口并行,但我只需要在需要时创建一个) 您知道JavaFx自定义弹出窗口的这种示例吗?我想我理解
您知道JavaFx自定义弹出窗口的这种示例吗?我想我理解您的要求,下面是一个(解决方法)示例:
- 我已经创建了两个FXML文件,一个用于主窗口(MainWindow.FXML),一个用于弹出窗口(popup.FXML)
- 为每个fxml文件创建了两个控制器类,这些控制器扩展了一个AbstractController类,所有有趣的事情都进入了这两个控制器
- 抽象控制器类只有一个方法,允许具体控制器访问主应用程序
- 在mainApp类中没有什么特别之处,只是加载主窗口的控制器并将主窗口设置为主舞台场景的根

哈立德·萨布的答案很好。如果使用sceneBuilder创建fxml文件,请不要设置setController(在函数showPopupUpWindow()中)
只要使用-
FXMLLoader=newFXMLLoader(getClass().getResource(“fxml.file”)
因为fxml文件会自动初始化相关类 我猜你的意思是弹出…你可以把你的弹出内容放在一个单独的阶段,并在必要时打开这个阶段。在弹出窗口中还有一个“OK”(确定)按钮来关闭这个
阶段。这可能会有帮助,谢谢,是的弹出窗口请看一下这篇文章:是的,这正是我要找的。谢谢!不客气:),如果您认为正确,请不要忘记将此答案标记为正确答案;)这个例子很好用,github文件也很好用。
