java - 使用ICEpdf“内部” Java程序

我们已经创建了一个程序作为单分配，并希望使用ICEpdf或其他用于Java的pdf查看器。

我们创建了不同的选项卡，用户可以在其中一个选项卡中选择一个pdf文件以“上传”并查看。问题是我们希望这样做，以便用户可以在应用程序内部查看pdf，而ICEpdf当前会创建一个额外的窗口并单独显示pdf。

可以使用ICEpdf查看器组件来实现吗？

随附一些图像以帮助解释发生了什么。



编辑/更新：基本上，ICEpdf需要一个jframe，而我们需要它在当前窗口中运行。

You will need to get border pane in your current window pane
