javafx controlfx 对话框给出错误答案

【问题标题】：javafx controlfx dialog box gives errorjavafx controlfx 对话框给出错误

【问题描述】：

我使用以下代码在当前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jar

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：

错误显示ControlsFX Error: ControlsFX 8.0.6_20 requires at least Java 8u20，所以我安装了jdk-8u20-ea-bin-b22-windows-x64-08_jul_2014.exe，但错误仍然相同。

请帮帮我。

【问题讨论】：

您是否更改了项目设置以使其使用新安装的 java 版本？
不，我该怎么做
很难说。不知道你用的是哪个IDE。在大多数情况下，右键单击项目树中的项目并转到属性。在某个地方，您会找到使用过的 java 版本。这取决于您的 IDE。
然后通过右键单击项目进入属性。之后进入图书馆。在那里你会找到java平台。选择新的或去管理平台 o 将其添加到列表中，如果它还没有在列表中。现在您想将源/二进制格式更改为 Java 8，以便能够使用 Java 8 的所有功能，例如lambdas。

【解决方案1】：

嘿，伙计，我使用了警告，我想要的工作

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

【解决方案2】：

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 运行 .jar 文件，则效果很好:)

我看到在 Netbeans 中设置的 JRE 是 1.8.11，我无法将 JRE 1.8.20 设置到我的机器中。

编辑：我在我的案例中解决了这个问题：editing the Netbeans config file

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”，然后浏览至 /Applications/NetBeans/NetBeans\ IDE\ 6.5.app/Contents/资源/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

我们需要在这一行中用 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，完成后，复制一份 netbeans.conf 文件:)
