In QT 4.6 w/ Webkit: How to handle popup window requests (WebView::createWindow)?

Question

Hi all,

I'm new to QT and have been trying to create a test browser. What I'm trying to do now is to handle js-based popup requests. After reading the QT documentation, I learned that I need to re-implement the QWebView::createWindow method to do just that.

Now I've re-implemented this method, but it seems to be not called when I try to click a link that triggers a popup window.

Can any one help me? Do I need to subclass both the WebView and WebPage classes? If so, how do I do that? I'm quite new to QT and I've done tons of searches and found nothing.

Thank you all in advance for any hint and advice!

Answer 1

Did you remember to set the following options?

view->settings()->setAttribute(QWebSettings::JavascriptEnabled, true);
view->settings()->setAttribute(QWebSettings::JavascriptCanOpenWindows, true);

And don't forget to call the parent class createWindow() method. The documentation has a note on that:

Note: If the createWindow() method of the associated page is reimplemented, this method is not called, unless explicitly done so in the reimplementation.

Answer 2

Nevermind my second question (in the comment area), here's what I did to capture the new window request (many thanks to Duncan's hint!):

page()->settings()->setAttribute(QWebSettings::JavascriptCanOpenWindows, true);

This was used inside the initiation process of the custom WebView class.

Hope this can be useful to someone. Thanks!
