Hello Dave,
if you have many widgets which have to be created, but only a few of
them are visible at the same time you could try to implement them as
singletons and reconfigure them for each usage or pool widgets:

Please let me know if this is a solution for you.
Cheers,
Jonathan

I have a somewhat complex dialog box that I use for program
settings. There's
a list view on the left and a tab control on the right. For each
entry in
the list, there's a separate copy of the tab control. There are four
tabs in
each tab control. So there are a total of 16 tab panes. (Of course
only one
is visible at a time.)
This dialog takes over 15 seconds to come up on a Xeon 5160 running
at 3Ghz.
I know IE7 is inherently slow, but this seems truly remarkable.
Under IE8 on
a Core i7, the dialog comes up in under a second. It seems like
something is
going on that's trigger nonlinear behavior in IE's DOM model.
Do QooxDoo veterans see this kind of slowdown with IE7? Is it just
that
there are too many tab panes?
Is there some way to precompute a DOM tree so that it doesn't have
to be
built dynamically every time I call up the settings dialog?
(I'm sorry if this is a bit short on details; I can't easily factor
out the
code to make a nice demo of the problem right now, but I thought it
was
better to post something than not.)
Dave
