156321 - pageXOffset and pageYOffset values are not updated correctly

Status: RESOLVED WORKSFORME

(Core :: DOM: Core & HTML, defect)

Description

[Gérard Talbot]

Clicking on xul:slider or on xul:scroll elements (of the scrollbar) do not
update the pageX/YOffset values. The scrolling of the document view happens but
the pageX/YOffset values get updated only on the next, following click. Always
reproducible. Windows XP Pro. Mozilla 1.1a+ build 20020707.

Attachment: Self explanatory test case

When the pageXOffset value show 0, try the following. 
Click on xul:slider of the horizontal bar: the horizontal scrollbar will
advance but the pageXOffset value will remain 0. Now, click on the xul:slider
of the vertical bar: you'll see that the pageXOffet value will update in the
table form but the pageYOffset will still remain 0. The same phenomenon is
observed when one clicks on the xul:scroll elements. This behavior is obvious
when one alternates from one scrollbar to the other. The scrolling happens on
the document view but the page*Offset value get updated only on the next click
onto the other scrollbar.
I have observed the same behavior with elements with scrollbars.

See attachment 90426 [details] of bug 62536 for a very similar - and most likely very much
related - behavior.

To DOM extensions.  The same happens if I click on a scrollbar thumb once....

nice test case.

I think this bug may depend on bug 179857 as well ...

What are the remaining issues here?  Scrolling by click works correctly now that
bug 179857 is fixed.  Scrolling with keyboard does not fire onscroll events at
all, looks like....

OK.  Then this bug is worksforme; the remaining issue is bug 189308
