Description: The Qt Sensors - Explorer QML Example on macOS is not usable when the dark theme is enabled due to poor text visibility. Text elements within the application do not have sufficient contrast against the dark background, resulting in difficulty reading and interacting with the content.

Steps to Reproduce:

1. Build and Launch the Qt Sensors - Explorer QML Example.
2. Ensure that the system's dark theme is enabled.
3. Observe the text elements within the application, such as labels, buttons, and menus.

Expected Behavior: Text elements should exhibit sufficient contrast against the dark background, ensuring readability and usability of the application.

Actual Behavior: The text elements within the application are barely distinguishable from the dark background, leading to poor text visibility. This makes it challenging to read and interact with the content effectively.
