Qtvirtualkeyboard embedded widget jetson does not work

[tyggylpp]

I am using Qt5.9.5 on the jetson tx2 platform, the source code is cross-compiled and used normally. The example in virtualkeyboard works fine on the device, but the virtual keyboard cannot be displayed in my own QWidget project.
Plugins can be loaded.
Qml project uses xcb or eglfs successfully, but qwidget fails.

@tyggylpp Hello, I got quite similar problem. How did you resolve yours? The qtvirtualkeyboard is functioning but it is invisible, so when I click on widget, letters are typed in the text field but I can not see where the keyboard is.
