return QWebElement& from QWebElement::setAttribute()

[Piotr Dobrogost]

How about returning QWebElement& from QWebElement::setAttribute() to make chaining possible?
I guess other methods of QWebElement could take advantage from this change as well.

Changing the return type is not binary compatible (see http://techbase.kde.org/Policies/Binary_Compatibility_Examples#Change_the_return_type).
It could be done for Qt 5, though.
Tor Arne, what do you think? Was this considered in the API reviews?

[Antonio Gomes]

maybe RESOLVED - LATER instead of INVALID, so we can revisit it at some point?

[Tor Arne Vestbø]

Chaining was not considered a goal for this API, as in most cases a normal semi-colon and multiple statements does the same job and is more in line with Qt's existing APIs.

foo.setAttribute("foo", "bar");
foo.setAttribute("biz", "baz");
