在 JavaFX 中激活触控控件 [英] Activating touch-enabled controls in JavaFX

问题描述

我想使用 http://docs.oracle.com/javase/8/javafx/user-interface-tutorial/embed.htm.我在 Windows 8 平板电脑上构建我的应用程序，但是 ScrollPanes 是桌面风格的，即带有 scrollbars 并且对手指没有反应 -拖着.如何告诉 JavaFX 我在移动平台上?

I want to use the touch-enabled controls described in http://docs.oracle.com/javase/8/javafx/user-interface-tutorial/embed.htm. I'm building my application on a Windows 8 tablet, but the ScrollPanes are desktop-style, i.e. with scrollbars and no reaction to finger-dragging. How do I tell JavaFX that I'm on a mobile platform?

编辑:我刚刚意识到标准的桌面样式 ScrollPane 确实会对手指拖动做出反应，但它看起来不像链接中的示例以上.

Edit: I just realized that the standard, desktop-style ScrollPane does react to finger-dragging, but it doesn't look like the example one in the link above.

解决方案:可以通过设置 -Dcom.sun.javafx.isEmbedded=true 和 -Dcom.sun.javafx.touch=true 来启用这些功能

Solution: the features can be enabled by setting -Dcom.sun.javafx.isEmbedded=true and -Dcom.sun.javafx.touch=true

推荐答案

应该不需要启用这些功能，但 JavaFX 会自行决定是否支持它们.您可以以编程方式查询功能，例如由 PlatformImpl.isSupported(ConditionalFeature.INPUT_TOUCH).

There should not be a need to enable these capabilities, but JavaFX decides by itself if they are supported. You can query the capabilities programmatically, e.g. by PlatformImpl.isSupported(ConditionalFeature.INPUT_TOUCH).
