282195 - Click+holding below scroll elevator, then moving cursor down, doesn't result in additional scrolling

Status: RESOLVED FIXED

(Core :: XUL, defect)

Description

[:deanis74]

Windows-only bug, spun off from bug 153946.  caillon fixed this for OS X and
Linux, but I'm still seeing it on Windows.  Maybe the NS_MOUSE_MOVE event isn't
getting through.

caillon only fixed it for the case where you move the mouse while scrolling.
(And you keep it scrolling you have to keep the mouse over the slider!)
Once it stops scrolling it won't restart.

Worse still, mousing over the thumb cancels the repeat too :-(

Attachment: Minimum patch

This is the minimum amount of work to fix the bug. By capturing the mouse we
can delay clearing the mChange flag until the mouse is released, thereby
allowing us to resume the repeat if the mouse is moved back over the slider.
Notes:
* Rename the functions because we're not just dragging the thumb?
* Make mChange a smaller data type?
* Inline HandleRelease?

Neil, I think you're actually fixing bug 234300, not this bug.

Aha!  That's the bug I was looking for.  Dupe that against this one, since we've
got a patch here?
