How to remove the need for UI files and build a window entirely with code?

? Offline

Hello all, hope everything is well! Currently, I am trying to figure out how to remove the need for UI files and build an app in Qt entirely from code. Specifically, I want to be able to create an app with just header and source files. How would I do this?

@sierdzio Thank you very much! Do you know of any examples of this that happen to be on the QT website?

Yeah, almost all of them do :-)

You just have to use all the UI classes (QHBoxLayout, QVBoxLayout, QWidget, QListView etc.) manually in C++. This is, by the way, exactly what UI files do: they are converted into C++ code by uic and then compiled using normal c++ compiler.

I do not use ui files as well. But often it is useful to create test ui files with designer and generate ui_code for help when some layout problems show up.
