Checking out Qt examples for limitations of .qml files

Analyzing exsiting Qt 6.6 examples for issues created for the visual tooling in .qml files.

Why do certain .qml files/projects not work in our visual tooling/QDS?

This is collecting concrete issues found in our examples.

Closed cases work well without issues.

Typcial issues are:

• Components have no default size and/or refer to their parent (which does not exist if created standalone).
• Usage of ApplicationWindow (should be fixed)
• C++ dependecies
• Usage of imperative code to populate items (in onCompleted) or that deals with layouting. This "breaks" the visual editor.

Many QML files nevertheless work fine.

Some examples like todolist, thermostst were done with QDS in mind and work well.

Some QML files are pushing the QML usage and fail to work in visual editor without clear reason. e.g. StartUpView.qml in quick3d/particles.
