Hello Jimlef,

Without thinking about Upp, you could implement in second and third window a reference to the master window (the first one opened), then with this references, you can access to all function of your 3 windows :

class MainWindow : TopWindow {
private:
    SecondWin second;
    ThirdWin  third;
public:
    MainWindow() : second(*this), third(*this){}
    
    SecondWin& GetSecond(){return second;}
    ThirdWin& GetThird(){return third;}
}

class SecondWin : TopWindow {
private:
	MainWindow& mainWindow;
public:
    SecondWin(MainWindow& _mainWindow) : mainWindow(_mainWindow) { /*Your code here, can be in .cpp too */ }
    SecondUpdate();
}

class ThirdWin : TopWindow {
private:
	MainWindow& mainWindow;
public:
    ThirdWin(MainWindow& _mainWindow) : mainWindow(_mainWindow) { /*Your code here, can be in .cpp too */ }
    DoSomething(){
		//Here I call the SecondUpdate() function from SecondWin:
		mainWindow.GetSecond().SecondUpdate();
    }
}

Hope it helped ! Very Happy
