You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: main.go
    path of file: ./repos/qt/internal/examples/qml/drawer_nav_x
    
    the code of the file until where you have to start completion: //source: https://github.com/ekke/drawer_nav_x

	var appui = initApplicationUI()

	// from QML we have access to ApplicationUI as myApp
