Is this standard?

[Jawache]

I've just seen this in some code (CLabel from CodeProject).... i've nver seen syntax like this before but it works!!

m\_monty
	.SetFontName("Arial")
	.SetFontSize(12)
	.SetTextColor(RGB(255,255,0))
	.SetFontUnderline(TRUE)
	.SetBkColor(RGB(0,0,0))
	.SetFontItalic(TRUE)
	.SetFontBold(TRUE)
	.SetBorder(TRUE)
	.SetSunken(TRUE);

is this standard C++ or just a vc++ thing? Asim Hussain e: asim@jawache.net w: www.jawache.net

My guess is that these functions in the CLabel class return a CLabel& . That way you can chain many function calls together in one line (or many lines for that matter). It could also be written as: m_monty.SetFontName("Arial").SetFontSize(12).SetTextColor( etc )...

Yes it's standard. The methods return a reference to an instance of the class. Pavel Sonork 100.15206

This is not the least bit standard. It's the result of someone trying to be cute. Certainly it works - see the other responses for why - but it's pointless.

It's "cute" coding following the style of STL streams, where you can chain a lot of stuff together like:

cout << "Hello " << "Bob" << endl;
