[hyades-dev] Hyades UI meeting notes (Nov. 10, 2004)

Meeting notes from this week's Hyades
UI meeting: 

Agenda:

Continue the filtering discussion (part
4). Use cases were written after the previous meeting to clearly define
what was talked about during the meeting. We will review these to ensure
a clear understanding. Some things that come to mind that we may need to
talk about: 

1. Multiple post-filters enabled at the same time or not? If so, include
an item in the drop down to disable all? 
2. In-line editing or edit dialog for criteria? 
3. Complexity of having to give your filters a name.
4. Associate filters with agents, agent types, or views?
5. Only show the last 10 filters in the drop down list?
6. How to make it clear to the user which filter(s) are currently enabled
in the view.

Time: 

Wednesday, Nov. 3, 12:00pm (noon) EST.

Notes: 

Here are the conclusions we reached:

1. A single filter enabled at a time.
2. Each filter is given a name by the
user.
3. Filters are shared among agent types
(i.e. profiling, logging, statistical). Different types of profiling agents
still share the same filters.
4. Last n filters will be shown in drop
down list (somewhere in the range of 5-10). List is sorted by time last
used.. most recently used showing up at the top. Least recently used filters
are the ones dropped when the list is full.
5. When setting a filter on one view,
it automatically applies to other similar views (those that apply on the
same agent type). This seemed to be the preferred approach over making
it view-based. Although there are arguments and use cases for both ways.
We can try this approach first, and see how it goes. In the future we can
add a preference and possibly change the default to make it view based
if we find that this approach is better.
6. If trying to apply a shared filter
that doesn't fully apply to a view, it does nothing. For example, if you
create a method filter in the execution statistics view then try to apply
that filter on the memory statistics view (where there are no methods),
it will have no effect.
7. This filter redesign work is targetted
to Hyades 4.0.

Things still not decided:

1. How to show which filter is enabled
on the view. The proposals were:
        a)
add filter name to view title
        b)
add filter name somewhere in the view
        c)
use a different icon for the filter button to show whether or not the view
is filtered
        d)
make the filter button a toggle button to turn on/off filtering
        e)
state how many things are filtered out (e.g. showing 100 of 150 elements).

2. How to turn off filters. The proposals
were:
        a)
a default filter set "No filters" that's always there in the
list
        b)
reselect the same filter in the list which causes it to toggle off
        c)
make the filter button a toggle button
