Well, there may be programming issues, but what I'm trying to figure out is purely Qt - how do you pass a variable in a signal/slot?

In normal C# you would do:

onButtonOKClicked() {
	string str1 = "string";
	ChangeText(str1);
}

ChangeText (string str2) {
	txtEdit.Text = str;
}

but in Qt this doesn't work:

signal(btnOK, SIGNAL("clicked()"), this, SLOT("ChangeText(str1)")); - it says no such slot

This is all I'm trying to figure out - how do you pass a value in a signal/slot?
