Bad usability with mouse scroll [message #641417] Thu, 25 November 2010 11:18 Go to next message

hello

We have some ugly issue with mylyn and trac, but I think this is may be true for
all connectors.
Users who are filling new ticket form sometimes are starting from description
(textarea), then they set up all other fields (mostly selects). Mouse scroll is
working when focus is on textareas or just on window. Using that with focus on
selects will change select option. This cause unexpected data submitted in task.
We had many issues with that because users were using mouse scroll to scroll
window, not options. They sometimes assume that scroll is not working and just
use slider, but it's because selects are scrolled.
Is there a way to disable mouse scroll in selects or change it to scroll entire
window only?


BTW: Trac 0.11 + XML RPC will show in eclipse select with milestone also when
user have no privilege to set up milestone. Web interface shows that in grey.
Using eclipse with mylyn users are not only able to choose milestone, but also
they can submit that data. Is this known problem with older version of trac (and
maybe xml-rpc) or should I report that? We will soon upgrade to newest version.

the behavior of scrolling is platform dependend. On Windows it will
generally scroll the control that has focus. You can find some background on
these bugs:

As far as I know, the Trac connector does not have explicit support to check
if a user has edit permissions for certain fields. Please feel free to file
an enhancement request: http://eclipse.org/mylyn/support/

I've just tried firefox and IE and both of them are not scrolling selects.
Looking at more than five programs I found only one that does this. You are
right that Eclipse stays consistent with "system bechavior" but usually system
dialogs are not longer than window so there is no problem with them. That's why
I wrote that usability is bad, it's not bug.

I'll update my trac to newest version and see if that will help. It should not
accept such data.
