  Sorry for asking this question: Are the changes saved? If you go to project settings -> build and hit "Details" on the right, you will see the selected build targets.
  What is checked there? "Current Executable" or "all"? Are you running the executable, that is compiled? Sometimes, the debug target is compiled, but the release target is run and vice versa. Finally: What does the "Compile Output" tab say? Was the compilation successful or did it have errors?

  Hi, I help maintain an HMI project in Qt Creator where all the Qml was coded manually. To navigate screens we use a loader item. For "subscreens" within a screen we use another loader. Given my experience I'm having trouble understanding the recommended flow ( navigation ) approach to an application created in design studio.
  The tutorial and documentation suggests states to show/hide components on the screen. Pretty basic examples. I don't see how that would work for a larger application with multiple screens. Can each screen be a separate component where state determines what's visible? If so, are states also used to navigate between the screens? What am I missing.
  Any reference or guidance would be greatly appreciated, thanks.

  Is there a solution around to code and test squish python code with PyCharm?

  Yes, it's possible to use PyCharm, a popular Python IDE, to code and test Squish Python code. Squish is a cross-platform GUI testing tool that supports various scripting languages, including Python.

  It was ok for me until I read this topic and pressed Shift+F5 to reload without cache and now the fonts are missing for me too. Looks like some problem with cross domain references.
