Bug 84873 – Make ScrollView::scrollSize scrollbar-independent

• Component: Platform
• Status: RESOLVED FIXED

[Antonio Gomes]

This method is so far tied to the existence of scrollbars to identify a scrollview as scrollable.

for ports that disable scrollbars at FrameView creation it makes it impossible to use any ScrollAnimatorXXX method.

Why have the conditional at all?  Why not just calculate in your fashion irregardless of whether there are scrollbars or not?

Fair enough.

LGTM, but since I haven't touched this code in a long time (at least not in upstream repo) I think someone else should review too.  Thanks Antonio!

It seems that http://trac.webkit.org/changeset/115401 went in without any comments here explaining why it’s needed.

Ooh my :(

I did a bad job at first (pushed the wrong patch) and at second (amended the proper patch as a diff against what was committed originally) without a changelog entry :/

Darin, want me to revert both, and push it properly?

I’m not sure there is any significant benefit to trying to fix this now; I just would have liked to have a comment here in the bug explaining what happened.
