I did experiment a bit and noticed some strange behaviour. When extending from qx,ui.embed.Html, suddenly my <space> key is is not propagated to my custom HTML (in this case an ACE editor). When I change the code back to extending from Widget, it starts working again.
Since there are still many other things to do, for now I guess I keep the Widget as a base class (at least until my custom HTML starts disappearing :) — Peter On 25 Jul 2014, at 13:34, Mustafa Sak <mustafa....@1und1.de> wrote: >> So the layout manager could decide to throw away these children nodes, was >> not aware of that? > Yes, it could throw your elements away.
