Re: [tracecompass-dev] Search capabilities in Time Graph views
|
Hi Bernd,
Like Matthew, I would also lean towards the first option. Especially if
we can re-use parts of the Eclipse search dialog implementation, instead
of spinning our own.
The filter dialog I see more as a configuration dialog, and it could
eventually be augmented with more view configuration options. However
"Configure settings" and "Search" are two distinct actions, so I would
keep two separate buttons/options/dialogs, one for each one.
Cheers,
Alex

Hello
I have done an investigation on how to support searching in the Time
Graph views (e.g. the Control Flow view or Resources view). Right now,
there are no means available for that. Only filtering is possible.
I think it would be useful to allow the user to find certain entries
in these views. In case of the Control Flow view, users would be able
to search for a process name, thread ID etc.
I suggest to add a command to open a search dialog. This command can
be provided as view menu item, button and short-cut. The button in the
toolbar could be omitted because the toolbar seems to get crowded. For
the key short-cut, I would propose CTRL+F, which is the standard
Eclipse short-cut for find.
For the dialog I have looked at 2 alternatives:
Alternative 1) will open a dialog similar to the standard Eclipse
Find/Replace dialog. It will have a text field that where the user can
enter the search string. This can be realized by a combo box to be
able save several previous searches. The options to search forward,
backwards as well as options to search whole words, case-sensitive and
regular expressions can be provided. The latter three will be enabled
by checkboxes. In case of a tree with columns (Time Graph Combo, e.g.
Control Flow view), the search operation will search through all the
columns for each row in the view. (see
https://wiki.eclipse.org/images/6/6b/TraceCompass_FindDialog_Standard.png).
With this alternative is should be also straight forward to add
support for find next/previous using a short-cut (e.g. CTRL+K).
Alternative 2) will be a similar to the filter dialog that is
currently available. The dialog will have a text box for entering the
search string. Also it will show the Time Graph entries as a tree.
When entering a string the tree will filter out non matching items.
This will help users to narrow down the exact item that user is
searching for. (See
https://wiki.eclipse.org/images/2/2a/TraceCompass_FindDialog_Filter.png).
I personally tend to alternative 1) since it seems more natural for a
find feature.
Thoughts?
Cheers
Bernd
