Access UI elements from another class with a UI

hobbyProgrammer

I have two classes with Ui's
MainWindow and firstStackWidget

In firstStackWidget I'd like to access the MainWindow's Ui.

In my firstStackWidget a new menu is shown and I'd like to access that menu from there to connect it to a subclass of firstStackWidget.

I've already made them friend classes, but that didn't allow me to access the ui elements yet.
Is there anyone who can help?

The Ui's are declared private in the header files, don't change that.. You can delete the friend declarations. I ran into a similar problem calling a function in one QDialog from another. You have to add
#include " MainWindow.h" at the top of firstStackWidget.cpp. To call functions or slots in MainWindow.h, declare a variable of type MainWindow, then use "dot" to access MainWindow functions. In MainWindow.ui, choose the menu item you wish to access, right-click, go to slot triggered, then in MainWindow.h, change private slots: to public.

// MainWindow.h
//private slots:
public slots:
    void on_actionSomeMenuItem_triggered();

//firstStackWidget.cpp
#include "MainWindow.h"
...
firstStackWidget::someFunction()
{
//...
    MainWindow main;
    main.on_actionSomeMenuItem_triggered();
}

Do not access the MainWindow UI directly, create a slot for the desired UI menu item-triggered, then call that public slot from the other UI.
Please let me know if I left anything out.
