Allow Qt Virtual Keyboard to work with hardware keyboard

I am using Virtualkeyboard with simple chinese and everything works when i type a letter on the virtualkeyboard it gives me options for a word from pying library.

Now if connect an external USB keyboard and want to use the virtualkeyboard on the same time, the pying library or virtualkeyboard dont show the correct options for the words combination.

To reproduce the problem use Qt5.9.1 or newer version, use the USB Keyboard from PC open the Qt Quick Virtual Keyboard - basic example project.

Note: You must first enable all languages and recompile the virtualkeyboard qt library so that simple chinese input method is enabled.  

On the example change the input method language to simple chinese(where keyboard is querty). If you type a letter on the virtualkeyboard, on top of the virtualkeyboard will appear word combination in chinese, now type the same letter on the usb keyboard and the word doenst appear or is incorrect.
