Description Matt Lilek 2006-10-15 23:20:20 PDT

Textareas should respond to input from the scroll wheel/track pad but do not in ToT.  Scrolling over a textarea does not move the text at all.  Also, scrolling past a textarea in a page in shipping Safari scrolls the page up to the textarea, scrolls the content in the textarea, then when it reaches the end of the content in the textarea, it continues scrolling the rest of the page - this does not happen in ToT, the textarea simply scrolls by.

Testcase in a minute.

Any fix for this yet?

Comment 5 Matt Lilek 2006-11-16 15:15:05 PST

This seems to have regressed even further since I first reported it.  Originally, scroll wheel input was ignored, but the scroll bar/arrows on the textbox worked correctly.  Now the scroll bar/arrows are ignored as if they aren't there, the only way to shift what content is displayed in a textarea is to highlight and select up/down.

Filed bug 11632 on scrollbars not responding to events since r17770.

This appears to be because the code in RenderObject::scroll is not finding the RenderTextControl's internal m_div's layer, but rather is just seeing that RenderTextControl itself has no layer and giving up without scrolling.

I'm not sure what the right fix is here - it seems like overriding |scroll| on RenderTextControl might be safest?

Adele, this looks like a shadow DOM issue.

Comment 9 Dave Hyatt 2006-12-12 14:15:04 PST

Overriding sounds pretty good.  I did something similar for the impl of scrollLeft and scrollTop etc.

Comment 10 Adele Peterson 2006-12-12 14:31:12 PST

I'm rewriting the shadow DOM for this control right now.  I'll work on this after I've checked that in.
