6 years ago There is another issue when the virtual keyboard is correctly applied after applying the change mentioned above. The keyboard events from the virtual keyboard are sent to the textfield instead of the webview, which prevents the events from being applied to the text input element of the webview. The skin of the textfield is responsible for attaching/detaching the textfield to/from the virtual keyboard: https://github.com/javafxports/openjdk-jfx/blob/develop/modules/javafx.controls/src/main/java/javafx/scene/control/skin/TextInputControlSkin.java#L275-L288
In case of the RenderThemeImpl$FormTextField, instead of attaching itself, it should attach the webview. This is also how the virtual keyboard is managed for the webview in the HTMLEditor control: https://github.com/javafxports/openjdk-jfx/blob/develop/modules/javafx.web/src/main/java/javafx/scene/web/HTMLEditorSkin.java#L425-L436
The JavaFX virtual keyboard is not shown when an input field of type text in WebView receives focus.
I have found the cause to be that the editable property of the textfield is incorrectly set. The editable property of the textfield should be set to the inverse of the readonly attribute that is defined on the input field. The following line contains the culprit: https://github.com/javafxports/openjdk-jfx/blob/develop/modules/javafx.web/src/main/java/com/sun/javafx/webkit/theme/RenderThemeImpl.java#L456
When inverting the boolean value, the virtual keyboard is correctly shown as expected.
