[Solved] Change between Views

[demonking]

Hello Community,

i'm programming with my team a hobby Project.
We decided to use QML because we use an embedded system and you can easily create
some Designs.

But now we have a problem.
Each of our qml files is a View.

The Application start on a Main Frame with some Buttons.
When i click on a Button it should change the View to the Content of 1 qml.
This should also be able to go back to the Main View.
Is this possible only with qml?

The Problem i could see is, that we have to connect the ClickEvents with our C++ application to execute some function.

Edit:

Ok , now i have a solution, but a other problem.

main.qml:
@
MainMenu{}
@
MainMenu.qml:
@
StartGame{}
LoadGame{}
Settings{}
@
StartGame,LoadGame,Settings are themself qml files.

When i click on StartGame{} there pop a popup window an ask "really" .
if not i want go back to the MainMenu.
The Problem is, that i get an error that the reference is undefined

A Loader has fixed my problem ;)
