open Dialog with VirtualKeyboard instead show directly VirtualKeyboard

[poucz]

Hello,
I want to use dialog with VirtualKeyboard as Inputpanel.
Desired behavior:
When I clicket on textfield (or any oher input box), dialog with keyboard and textfield will appear.

Standard behaviour hidde input field.
Because I use GridView and ListView inside the Flickable. And delegates is Text field.
I try to use onFocusChanged on delegate to change flickable.contentY, but delegate contains another components and onFocusChanged not work.
