Hello,
The code doesn't seem to have anything to do with Qt, but instead has
something to do with WebView. It seems that WebView doesn't want to
load a page if it is inside a modal dialog. If I replace the Qt code
with straight Cocoa code, I get the same result. You may have to check
on some Cocoa sites to understand why as this is a bit outside the
scope of Qt.
If you need to display webpages inside of a modal dialog, you might be
able to do this QWebFrame.
Hope this helps,
-- Trenton
