What corresponds to native = "true" in the Qt constructor form

Question

I make a difference between the 2 versions of the project and noticed that some of the ui files have additional attributes in xml that I myself did not put there:

where would native = "true" come from? what would make it added to ui?

Answer 1

Qt GUIs can be displayed in many topics. native="true" forces the application to use the operating system theme (on Linux, some QT applications look awful because they are not like other native applications).
