Hi all,
I have implemented a solution which is a combination of Johns and Vogers
recommendation. I've implemented a general purpose mixin which I'm
currently using by adding it to qx.application.Standalone and calling
the method preloadImagesResources at the end of
qx.application.Standalone.main:
// overridden
main : function()
{
this.base(arguments);
// preload decoration
this.preloadImageResources("decoration");
}
This pre loads everything having the string "decoration" in its resource
path and being a png or gif. It takes care of combined resources. Here
is the gist:
https://gist.github.com/level420/e1d70de25889609c1f56
The method relies on the existence of the qx.$$resources array having
the structure as of today, gracefully stopping if not.
You may use it in every other class as well, as it does not assume to be
mixed in into qx.application.Standalone, but retrieving the root widget
via qx.core.Init.getApplication().getRoot().
And yes! The chrome flicker on check button and radio button state
changes stopped!
Thank for your help!
Regards
Dietrich
