Hi,
The example for QOpenGLWindow I came across in the qt source and google
search show them as the main window display.
I have not yet discovered an example which shows QOpenGLWindow use within
a UI application that has a menu bar and other widgets.
Is QOpenGLWindow designed to be used so
OK. I will look into the plugins approach.
Is dynamically loading UI files to be avoided in Qt development ? What are
the limitations (so I can learn about them) ?
Cheers

I guess since you're loading the UI dynamically, you'll need to either
go the "plugin" route or subclass QUiLoader.

I'm not sure why you're using dynamic UI loading in the first place, or
how you expect any custom objects

Hi,
Functional safety is a complex topic with multiple different standards

If you allow me my two cents:
I'm not a good enough programmer to know how does one deal with the

SpaceX's dashboard is literally an Electron application. So if a

The problem isn't Qt, it's not dashboards or medical. It's all about how you mitigate the risk.
I think Qt is fine for dashboards and medical, if the risks are properly managed. I think it is ok that a desktop app does not have the same risk profile as a medical device. What is important from a

Prime billing on QtC's front page is a picture of the combined
dashboard/infotainment system for the 2019 Mercedes-Benz A-Class.
Dashboard is definitely safety critical in eyes of regulators. Infotainment
system too if is integrated with backup cam.

I have a load cell. It's a sensor that measures weight. I wanted to make a
quick UI for it in Qt.
That went as expected. Then I wanted to put the app on a spare Amazon Fire
tablet rather than tie up a computer with it.
