Hello all

I would like to ask you how you design professional U++ applications.

Thinking in a GUI application with a main window, how do you connect classes with main class containing main Serialize/Xmlize configuration:

- Main class is a global variable.
- You include in classes constructor as argument a pointer to main class
- You access from a subclass the main class using dynamic_cast<MainClass *>(GetParent()->GetParent()-> ... as many times as necessary.

I usually use the global config scheme as well:

In your dialog cpp:

#define CONFIG_KEY "YourDialogClassName"

INITBLOCK {
	RegisterGlobalConfig(CONFIG_KEY);
}

before showing your dialog:

	LoadFromGlobal(*this, CONFIG_KEY);

After closing it:

	StoreToGlobal(*this, CONFIG_KEY);

And in your main window's Serialize method will be like this:

void MainWindow::Serialize(Stream& s)
{
	int version = 1;
	s / version;

	SerializePlacement(s);
	some_member.Serialize(s);
	SerializeGlobalConfigs(s);
	
	if(version<2) return;
	//this is used in newer versions
}
