QWebView - Showing portion of a webpage.

[TemplarKnight]

Hi everybody,

Can someone tell me if there is a way to show just a portion of a web page using a qwebview? For example, if I just want to see the Google logo, not the entire page... (This is just an example, it is not what I'm trying to do).

Regards,
Javier.

It all depends what you want to do. If you wish to see a particular image from the website then the easiest way is to find its url and download it. If you want a particular tag contents, then QWebElement::render() is something you should look at. If you want a part of the website based on geometry then have a look at QWebFrame::render(). If you want the part of the page to be interactive then well... it's not that easy

Hi,

Thanks for your reply. I ended up with the dirtiest trick ever, but it works for me this way, and do what I want... hehe

After the page load has ended, I simple move the scrollbars to the position I wanted, and then just hide them...

ui->webView->page()->mainFrame()->setScrollBarValue(Qt::Vertical, 900);
ui->webView->page()->mainFrame()->setScrollBarValue(Qt::Horizontal, 640);
 
ui->webView->page()->mainFrame()->setScrollBarPolicy(Qt::Horizontal, Qt::ScrollBarAlwaysOff);
ui->webView->page()->mainFrame()->setScrollBarPolicy(Qt::Vertical, Qt::ScrollBarAlwaysOff);

ui->webView->page()->mainFrame()->setScrollBarValue(Qt::Vertical, 900);
ui->webView->page()->mainFrame()->setScrollBarValue(Qt::Horizontal, 640);

ui->webView->page()->mainFrame()->setScrollBarPolicy(Qt::Horizontal, Qt::ScrollBarAlwaysOff);
ui->webView->page()->mainFrame()->setScrollBarPolicy(Qt::Vertical, Qt::ScrollBarAlwaysOff);

To copy to clipboard, switch view to plain text mode 

And that's all!

Kind of ineffective if one clicks on the webpage and uses cursor keys to move the view or resizes the window or zooms the webpage.
