One thing you can try to test this is to open a regular browser and OB and then just keep scrolling through the system categories with cursor up or cursor down. In the regular browser this entirely smooth; in OB it's "stuttering" and at least I notice the same delay when clicking on the list.

I find the tradeoff worthwhile - it's not that slow, and the extra information imparted by the sort order is useful - but reasonable people may disagree. It wouldn't be hard to make this a preference.

Nope it's not that. A bit of profiling shows the particular problem is
caused by some gross inefficiencies when updating. If you file in the
attached tweaks, OB scrolls just as smoothly as the standard browser.
I'm not sure if the tweaks have side effects though; you might want to
verify that (in particular because of the comment in
OBColumn>>switchFilter: which indicates some interference although I
can't see how that could make a difference if the filter is identical).

That is awesome, thanks! It seems to work fine; I've removed the comment. It's probably out of date, and if there are visual oddities, the fix is undoubtedly somewhere else.

Hi all,

I noticed that 'instance' '?' and 'class' do not show any visual clue

about their state, i.e. 'instace' button should be _selected_ when

browsing instance methods.

Do you experience the same issue?

Any solution (I searched around [mailing list and Mantis] but found nothing...)?

Thanks in advance

Bye

Enrico

Why would OB be a no-go? I am very happy with OB, and like it better
than any other Squeak browser.

I can't speak for others but in my experience OB is too slow to be of
any use. When interactions on a 2GHz dual-core box take seconds I
can't get work done.

I think that was OB + some other stuff (like automatic method
categorization). OB in itself is as fast as the default browser and some
has great features.

Interesting. My encounters with OB mostly originate from Pharo where it's always been dog-slow so I was never interested in looked deeper. Any ideas how to install OB without that stuff?

Try this:
Installer ss
project: 'rb';
install: 'AST';
install: 'Refactoring-Core';
install: 'Refactoring-Spelling';
project: 'Regex';
install: 'VB-Regex'.
Installer wiresong
project: 'ob';
install: 'OmniBrowser';
install: 'OB-Morphic';
install: 'OB-Standard';
install: 'OB-Shout';
install: 'OB-Refactory';
install: 'OB-Regex';
install: 'OB-SUnitIntegration'.

What I'm really missing is "Recent classes..." from the menu and the
movable splitters between the upper panels (aka resizeable panels). It's
really a PITA to resize the full browser to see the name of the current
category/class/protocol/method.

Do you mean the Browser in Trunk, or OB? Because in Trunk there is a
visual indication - see attached. OK, not MUCH of an indication. (Class
is selected.)
