View map in in Qt Designer, for Qt mapviewer example

[erso]

Hello,

I would like to view the MapViewer.qml file (https://doc.qt.io/qt-5/qtlocation-mapviewer-example.html) in the the Designer in order to better adjust buttons and changes in the map view. Currently I have the issue in the screenshot when trying to open the file. What can I do in order to view the full scene?
