RE: [Dynapi-Dev] TCanvas vs. DynLayer

[Pascal <pb...@oi...>]

me again :)

I don't think this test is really useable.
Your current Tcanvas code misses ALOT of things DynLayer takes care of.

DynLayer sets sizes, z-index,clipping,bgimages in initialisation (and also a
few other style properties.. note that setting a style property is what
slows everything down)  I once did some optimization tricks to the dynlayer,
by removing sizes/clipping etc.. this speeds up things BIG TIME, but also
brakes useability for a large amount of widgets, and is less flexible.

DynLayer has code included for fast child-creation.. even though there are
no child layers in your test, this code is still called (function calls).
This could be made faster in dynlayer, but for now is more readable for
developers.  Do another test with layers containing a large amount child
layers.. Dynlayer's precreation will probably be faster.


shreded enough? ;)
