Title Body

Consider: // member data omitted for brevity // assume that "setAngle" needs to be implemented separately // in Label and Image, and that Button does need to inherit // Label, rather than, say, contain one (etc) struct Widget { Widget& move(Point newPos) { pos = newPos; return *this; } }; struct Label : Widget { Label& setText(string const& newText) { text = newText; return *this; } Label& setAngle(double newAngle) { angle = newAngle; return *this; } }; struct Button : Label { Button& setAngle(double newAngle) { backgroundImage.setAngle(newAngle); Label::setAngle(newAngle); return *this; } }; int main() { Button btn; // oops: Widget::setText doesn't exist btn.move(Point(0,0)).setText("Hey"); // oops: calling Label::setAngle rather than Button::setAngle btn.setText("Boo").setAngle(.5); } Any techniques to get around these problems? Example: using template magic to make Button::move return Button& or something. edit It has become clear that the second problem is solved by making setAngle virtual. But the first problem remains unsolved in a reasonable fashion! edit : Well, I guess it's impossible to do properly in C++. Thanks for the efforts anyhow.
