Jasper报告组件无法在JavaFX Swing节点中正确呈现

Sat*_*uja 6 java swing javafx jasper-reports

为了在JavaFX 11中创建Jasper报告，我使用了动态报告。我正在将报告加载到Swing Node中，但是只有当我单击堆栈窗格区域时，才会显示Jasper报告，并且只有将鼠标悬停在所有这些组件上时，所有其他组件才可见。组件和报告内容不会立即加载，而不是在鼠标悬停时显示，并且在“堆栈窗格”上滚动时显示报告。

因为这是Java 8中的错误，似乎已经解决，但是在Java 11中，我也遇到了同样的问题。

更新资料

由于我没有得到任何回应，并且按照kleopatra的建议，我创建了最少的可复制代码。请调查一下。

输出量

单击加载报告按钮后，只有一个保存图标可见，没有报告可见。
单击堆栈窗格区域后，现在可以看到报告。
将鼠标悬停在另一个图标上后，现在可以看到“打印”图标。
将鼠标悬停在其他图标上之后，它们也将一一显示。

在检查 OpenJDK wiki 中的OpenJFX 调试标志后，您可以尝试以下操作。

添加pom.xmlOpenJFX 的 JVM 选项的构建部分

<plugin>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-maven-plugin</artifactId>
    <version>0.0.4</version>
    <configuration>
        <mainClass>demo.JavaFxJasperReportsDemo</mainClass>
        <options>
            <option>-Dprism.verbose=true</option>
        </options>
    </configuration>

执行该应用程序mvn javafx:run将报告检测到的 Prism 配置

它使用硬件加速渲染器Loading ES2 native library ... prism_es2

可以强制使用软件渲染器。变化在pom.xml

        <options>
            <option>-Dprism.verbose=true</option>
            <option>-Dprism.order=sw</option

那么输出是

Prism pipeline init order: sw 
Using Double Precision Marlin Rasterizer
Using dirty region optimizations
Not using texture mask for primitives
Not forcing power of 2 sizes for textures
Using hardware CLAMP_TO_ZERO mode
Opting in for HiDPI pixel scaling
