So i am basically almost done with my C++ App Logic Wise tho the only thing i struggle with and wanna figure it is how to include a seperate class into my main class constructors >.>

Mostly due to the fact that currently in my Code my main Code has 2 Objects tho ErrorWin Object is right now the only one that exist twice as seperate Objects which itd like to fix >.>

So this is my first Object in my Main Function which just calls my DisplayWindow Function while my ErrorWin Object calls the Display Error Window Function :P

int main() {
  ErrorWindow ErrorWin;
  MainWindow MainWin;

  if (ProgramPath.empty()) {
    ErrorWin.DisplayErrorWindow();
    return Fl::run();
  }

  MainWin.DisplayMainWindow();
  return Fl::run();
}

Now the Main Issue is that only my First Text basically gets displayed in the Error Window even tho my switch Statement is set to display a different error text basically according to my callback but that obviously does not work due to theyre being seperate ErrorWin Objects :(

void MainWindow::CallbackSaveFile(Fl_Widget* Widget, void* Data) {
  MainWindow* MainWindowData = static_cast<MainWindow*>(Data);
  ErrorWindow ErrorWin;

  if (!MainWindowData->InputFile.empty()) {
    ...
  } else {
    ErrorWin.DisplayErrorWindow();
  }
}

    First, in your main, you want judt ErrorWindow ErrorWin;. As it is, you’re taking a pointer to a pointer with the & (also it’s not initialized).

    Second, does your MainWindow.hpp know the ErrorWindow? You may have to forward declare it (write class ErrorWindow; at the top, to tell the compiler it exists without saying anything else). If you include the other header files respectively, they include each other, so you get a cycle.

      yup just removed the infinite cycle by just doing class ErrorWindow; inside mainwindow.hpp :P
      also if i remove MainWindow MainWin; from main then obviously all i get is a compiler Error as i require MainWin inside my Main Function >.>

      src/main.cpp:20:5: error: ‘MainWin’ was not declared in this scope; did you mean ‘MainWindow’?

        I did not mean to remove MainWindow from main, I meant you shoud change ErrorWindow* ErrorWin to ErrorWindow ErrorWin, because you don’t want a pointer variable, you want an instance, and then you pass a pointer to the instance using &ErrorWin as you did.
