Hugh, your way is good but it seems that I've found the most correct one (at
least I beleive that it is so :)). I could use it in any file and I think it
matches the rules of the qooxdoo. You may be interested in it too.
Here it is:
qx.core.Init.getInstance().getApplicationInstance()
This returns the link to the current application running. Then I'm using it
just like in your example:
var app = qx.core.Init.getInstance().getApplicationInstance();
app.getMyViewer();
Hope this may help you and some newbies like me ;)
Best regards,
Alexei Golovko
