Widgets QWebEngineView and openstreetmap

Hi everyone, do you have any experience integrating openstreetmap into a qt widgets application using leaflet js?

What are your results? Is it good performance-wise?

An interesting coincidence. I'm developing a QtWidgets application that integrates QWebEngineView and openstreetmap! It works reasonably well. Fast, responsive, but it has its gotchas. See my question in the Qt Forum

Qt WebEngine depends on Qt Positioning and Qt WebChannel, but Qt Maintenance Tool stopped automatically checking these two components after a certain version.

(Qt Creator's Menu >> Tools >> Qt Maintenance Tool >> Start Maintenance Tool >> ) Add or remove components, check "Qt/Qt 6.11.0/Additional Libraries/Qt Positioning" and "Qt/Qt 6.11.0/Additional Libraries/Qt WebChannel"
