    Hi, and welcome! @joeren said in Integration of QML and C++: The application that will publish the interface onto the module is called G2Link and will only push QML files. This sounds like a non-standard setup. I had a quick look at their website, but I can't see how to program their device using C++ at all. Your best bet is to contact tech support at Reach Tech.

    At the beginning of times, creating a GUI, be it on Windows or Linux, was something that wasn't easy to learn nor do and was not reusable at all. Qt was created to make the life of developers way easier as well as provide a framework that allows you to write your code once and then build it on a per platform basis. If you want another example, try to show an OpenGL window using native APIs vs doing with Qt. Qt is: simplicity elegance cross platform

    @JonB said in Create a method that takes in a sorted array of integers and returns a sorted array of the same integers.: My loop only runs while (i < j). I was too concentrated on the loop body, so I overlooked that. You are right!

    I am new in QT using C++ 98 It's almost 2023. It's time to move on :) As for the code - it's kinda all over the place. You're just iterating over some widgets. Why do you even need a signal mapper here? Especially since you map those widget to themselves? That doesn't make sense. find_child will return nullptr if it couldn't find anything. You're not checking that so you're probably getting nullptr and then trying to call btn->setStyleSheet on it. That will crash. Those buttons don't seem to be children of the signal mapper. At least there's no code here that would make them that. Your signal mapper doesn't have any children here, so find_child won't find anything and will return nullptr. You should call find_child on the actual parent of those buttons. In any case, find_child operates on object names, not variable names. Are these widgets actually named with setObjectName()? If not then find_child will not find them and return nullptr.
