Show QML Dialog before mainwindow

[itzwich1]

Hallo together,

I have a problem and no idea if it is possible to solve.

I have a normal mainwindow like a QML Window or a ApplicationWindow.
Before this window is visible I would like to show a simple qml dialog (like a login dialog). If login was successfull my normal mainwindow should visible. If not mainwindow should not visible.

Is it pssible to show a QML Dialog without a ApplicationWindow?
If yes how could I reach that.

Thanks Felix
