The KPart's widget in most cases (at least in khtml and kwebkitpart), uses the actual content viewing widget its focus proxy. That is why this patch attempts to use the focus proxy widget when available.

This is a workaround for a yet to be identified issue with the entire QWebView flickering and losing the flash plugin display when you attempt to popup a context menu using the KPart's widget as the parent of the popup menu. That problem does not occur if the QWebView is used as the parent widget of the context menu. No clue why this happens though. What is even more bizarre is if you simply reload the page and right click again, you will not see the flickering again. It only happens the first time the context menu is shown a page embedding a flash plugin.

This is an upstream QtWebKit issue. I cannot duplicate the problem with the current trunk version.
