Speed of LayoutManagers

[Stefan Schmiedl]

Greetings,

are there any speed comparisons between different layout managers?

Today I dabbled around with JGoodies.com's FormLayout and found that
it took 0.3s to open a sample layout, which took 0.4s when drawn with
NetBean's Matisse (FreeLayout?).

I am aware that different Layout Managers are intended for different
purposes, I just wondered if there was something like a "Grauert-Brief"
(standardized business letter often used for comparing printer speeds).

Thanks,
s.

Almost all of the time should be in get(Minimum|Preferred|Maximum)Size
calls. Hopefully these are only done once. I don't know why FormLayout
is faster, but perhaps it doesn't use all of them? A profiler might help.

Hi Stefan,

I am not aware of any speed comparisons between layout managers. I am
aware though that the GridBagLayout that everyone loves to hate can be
lightning fast. According to Ethan Nicholas the "GridBagLayout is fast,
stable, and lets you program complicated layouts with a minimum of
components." Have a look at this link
(http://www.javalobby.org/java/forums/t1173.html) and part way down you
will see Ethan's tips. Two of those tips deal with layout managers.
Here is another link to Ethan's blog
(http://weblogs.java.net/blog/enicholas/archive/2006/04/reinventing_gri.html).

Cheers,

Dan Andrews
