我使用以下代码在我当前的项目中打开一个对话框，因为我已经阅读了 controlfx 及其很棒的对话框，所以我在我的项目中使用了它的代码，但它给出了错误，我不知道为什么？

 Dialogs.create()
        .owner(SchoolManagement2.stage1)
        .title("Information Dialog")
        .masthead("Look, an Information Dialog")
        .message("I have a great message for you!")
        .showInformation();

我添加了以下罐子

controlsfx-8.0.6_20.jar
controlsfx-samples-8.0.6_20.jar
fxsampler-1.0.6_20.jar

我收到以下错误：

嘿，伙计，我用了警告，我想要的作品

警报警报 = 新警报（AlertType.WARNING）；

        alert.setTitle("Warning");
        alert.setHeaderText("Look, a Warning Dialog");
        alert.setContentText("your content text!");
        alert.showAndWait();

你不需要添加 controlfx.jar，javaFx 已经有了它只是导入

我正在使用 Netbeans 和 Mac OS ML。

我有同样的问题，我无法从 Netbeans 运行我的程序。但是，如果我从 Netbeans 中运行 .jar 文件，则可以正常工作:)

我看到在 Netbeans 中设置的 JRE 是 1.8.11，我无法设置安装到我的机器中的 JRE 1.8.20。

编辑：我在我的 cas 中解决了这个问题：编辑 Netbeans 配置文件

  • 在 Mac OS X 上：按住 Ctrl 键单击 Finder 中的 /Applications/NetBeans/NetBeans IDE 6.5.app 并选择“显示包内容”，然后浏览到 /Applications/NetBeans/NetBeans\ IDE\ 6.5.app/Contents/Resources/NetBeans /etc/netbeans.conf。
  • 在 Windows 上：C:\Program Files\Netbeans\etc\netbeans.conf
  • 在 Linux 上，安装程序允许用户选择要安装 NetBeans 的位置。您可以在 /home/yourname/netbeans/etc/netbeans.conf 或 /opt/netbeans/etc/netbeans.conf 下找到它。

见：http ://wiki.netbeans.org/FaqNetbeansConf

我们需要在这一行用jdk1.8.0_20替换当前的 jdk ：netbeans_jdkhome="/Library/Java/JavaVirtualMachines/ jdk1.8.0_11 .jdk/Contents/Home"

为了安全起见，在此之后，复制一份 netbeans.conf 文件:)
