Multiple QMainWindow instances

[viniltc]

Hi all,

I'm working on an application which has multiple QMainWindow instances. I named those as:
StageOneMain, StageTwoProg and StageThreeProg etc.

I also have another class say tetra_grip_api , need to be accessed in all of these forms (which is like an API).

StageOneMain is the first window , I pass the pointer to the tetra_grip_api instance to constructor of StageOneMain. So my main looks like this

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    tetra_grip_api api;
    
    api.openSerialPort();
   
    StageOneMain w(nullptr, &api);
    
    w.show();
    return a.exec();
}

Other windows will be called from StageOneMain. My question is where do I pass instance of tetra_grip_api to the constructor of other forms. Do I need to mention those forms in the main?

Thanks in advance

If you store the API pointer in your StageOneMain, you can pass it to StageTwo and StageTree when you construct them.
