[Qt-interest] Launching new browser from within QtWebKit

[Darryl Hunter]

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
