JavaFX virtual keyboard

Question

Is there such a thing? I have a javafx googled virtual keyboard, but nothing seems like it really is. I saw this article but no code or example

http://docs.oracle.com/javase/8/javafx/user-interface-tutorial/embed.htm

Does anyone have experience with a virtual keyboard in a javafx app? When the text box is focused, I need to show a regular keyboard or numeric keypad.

Answer 1

Yes, there is such a thing as the JavaFX virtual keyboard in the Oracle Java 8 distribution, although it is not documented or supported by Oracle outside the built-in version of JavaFX.

However, the virtual keyboard seems to come with the Oracle 8 JRE desktop Java platform and seems to work there if you switch some undocumented and unsupported system properties.

Try:

• -Dcom.sun.javafx.isEmbedded=true

Or maybe

• -Dcom.sun.javafx.touch=true
• -Dcom.sun.javafx.virtualKeyboard=javafx

Some related outline information on the Internet:

• Activating Touchscreen Controls in JavaFX
• JavaFX 8 Embedded Mode Oracle JavaFX Forum Post.
• JavaFX WebView / WebEngine automatically displays an on-screen keyboard for each text input

The guys at javafxports can know more, so you can try asking there if you want more information (if you target one of their devices).

Answer 2

if you are confused, here, catch:

1. right-click your project (in Netbeans)

2. Click Properties → Run →

3. Complete [VM Options] with

  -Dcom.sun.javafx.isEmbedded=true -Dcom.sun.javafx.touch=true -Dcom.sun.javafx.virtualKeyboard=javafx 

4.OK done

Answer 3

To be sure, you must add flags.

• -Dcom.sun.javafx.isEmbedded=true
• -Dcom.sun.javafx.touch=true
• -Dcom.sun.javafx.virtualKeyboard=javafx

in javavm and not in the application ... (added as a message, since I can not comment ...)

Is a keyboard setup required? check /com/sun/javafx/scene/control/skin/caspian/fxvk.css in ${JRE/JDK_INSTALL}/jre/lib/ext/jfxrt.jar for css fields affecting the keyboard.
