[Qt-interest] Launching new browser from within QtWebKit

[Nguyen Huu Phuoc]

Hi Darryl


I know that QWebView has a signal is void QWebView::linkClicked ( const QUrl
<http://doc.trolltech.com/4.6/qurl.html>  & url )


You should write your slot to process this signal.


If url has target=’_blank” you should call default browser to load url


Otherwise you should use QWebView to load url.


Hope help you a bit.

Hi all,



I posted this on the weekend and had one response, which isn't quite
flexible enough for my requirements.  Does anybody else have any
suggestions?



My issue is that I need to *optionally* spawn a new browser from within a
QWebView.  When I set target="_blank", it won't launch the page.



I was given the suggestion of connecting to the linkClicked signal and using
QDesktopServices::openUrl, which works when following links, but does it for
*all* links.  I only want to do this if target="_blank".



Any suggestions?



Thanks.



Darryl

Thanks Sarvesh.



I implemented your suggestion and that worked for opening the default
browser.



However, one part I omitted from the original post, was that not *all* of
the links should open a browser - sometimes I want it to stay within the
existing window.  So I need it to look at that target="_blank" part
somewhere in between to determine whether to handle it in the WebView or
start the default browser.  This isn't in the QUrl object though (from what
I understand - happy to be proven wrong on this point!).

Hi,



I remember facing this same issue a long time ago. You can try the following
:



webView->page()->setLinkDelegationPolicy(QWebPage::DelegateAllLinks);



connect(webView, SIGNAL(linkClicked(const QUrl&)), this, SLOT
(onUrlClicked(const QUrl&)));



in the slot, use  QDesktopServices::openUrl  to open the url in your default
browser:



http://doc.trolltech.com/4.5/qdesktopservices.html#openUrl



( if using Linux, you can try and check if $BROWSER env variable is
set...and then use QProcess to open that browser, passing the Url as a
command line arg)



thanks,

Sarvesh Saran

Hi all,



I'm using Qt 4.7.1, on Windows 7.  My application has a QWebView in it,
which has loaded a page from my server.  I want to have a link that, when
clicked, opens the users default browser to show the page, rather than
opening it within the QWebView.



I set target="_blank" on the page, and it works fine when I test it within
Internet Explorer (a new copy of IE is launched), but when I follow the link
within the QWebView, nothing happens.  If I don't have the target="_blank"
then it follows the link as you would expect (within the QWebView).



Is there a setting I need to enable to make this happen?  I couldn't see
anything in QWebSettings that appeared relevant.



Any help / suggestions would be greatly appreciated.



Regards,



Darryl
