Unreal Engine 4 + Qt Widget

Working on project with UE4. I want to create UI with using Qt Designer and all Qt UI tools. I have already done opening window with some Qt forms (treeview and group of checkboxes) but I failed transmit picture from Unreal Engine window to QWidget.

I read about HWDL window, but i didn’t found any information about realization. Found only how to get HWDL from UE4, but didn’t found how to set to QWidget or wise versa get HWDL from QWidget and set it for UE4 (I think the second one better).

Maybe someone have done it? Or know approach to do it.
