[Qt-interest] QWebView and backspace key

[Constantin Makshin]

I think it wouldn't be a bad idea to file a feature request to make QWebPage able to not only return and trigger page actions, but also override and/or completely disable them — something like
QWebPage::setAction (WebAction webAction, QAction* action)
and
QWebPage::enableAction (WebAction action, bool enable).

This won't solve the problem "here and now", but may help you and others in the future. And definitely any of those solutions are better than manually clearing the page history each time it changes.
