<span> With Steven Boswell's help, I've fixed the </span>QX11EmbedWidget/QX11EmbedContainer problem when building Qyoto on Linux. Now the classes are no longer excluded and build with no
errors.</div><div style="font-style:normal;font-size:16px;background-color:transparent;font-family:times new roman, new york, times, serif;"><span> Steven, I've fixed this by checking for nested types when generating signals. I've taken a look at your patch and it seems OK. But there are many changes and I wanted to think on it a little longer, to see if it's possible to exclude a class at a single central place. About this other fix I've applied, I had to do it anyway because these two classes were only blacklisted because of it, and there may be other similar in future Qt versions.</span></div>
