I am working on a QML application and after the last issues were solved I am
attempting to refactor the code so that common sets of QML codes are in their
own .qml files.
The issue that I am having is that now that I am using TabView{} and associated
“Tab” widgets, when I go to reference a TextField that is buried down in one of
the tabs I get the “ReferenceError: minZThickness_TF is not defined” error. If
I move that QML object as a child of the root QML object then things work, but
obviously the display is now busted. Has anyone else seen anything like this
before? I’ll attach my QML file to the end for the curious.
