我正在尝试实现能够制作的JavaFX应用程序使用触摸事件和多点触控手势。我正在和一个人一起工作电容式触摸屏-eGalax Touch设备，带有EETI eGTouch 驱动程序（eGTouchD版本：2.5）。它连接到Ubuntu 16.04 LTS PC 通过USB和创建的多点触摸事件（ABS_MT_SLOT， ABS_MT_TRACKING_ID，ABS_MT_POSITION_X，ABS_MT_POSITION_Y）哪个可以从终端的/ dev / input / eventX读取。我已经尝试了很多方法（包括MT4j）来实现它，但它们都不能认识到触摸事件。

但在Windows 7下，识别触摸事件的代码相同，我可以滑动，捏合，缩放等。现在，放大和缩小事件也可以通过Ubuntu和Wondows 7中的鼠标滚动事件来实现。
相比之下，我发现在Windows 7中java 8 JDK提供了一个 jar叫java-access-bridge.jar，但在Ubuntu的JDK中却没有包括在内。这是问题的关键吗？
因为我刚开始熟悉这些东西，所以我很感激任何提示或帮助。

如何通过javafx在ubuntu 16.04中开发多点触控应用程序？
