Bug 43169 – [Qt] Html autofocus not working with QGraphicsWebView

• Component: WebKit Qt
• Status: RESOLVED FIXED

[Antonio Gomes]

Launch QtTestBrowser in graphics-based mode with

$ run-launcher --qt -graphicsbased http://google.com

the google page auto focus on the main textfield after it finishes loading the page. However, with graphicsbased QtTestBrowser it does not work, while works fine with QWidget based (QWebView).

The problem seems to be that QGraphicsScene only propagates focus events if they are caused by tab or backtab in cases where there is no active focus item. Only way around this that I can see is to install an event filter on the scene to capture the focus events.

I'll upload a possible patch shortly.

Is it possible to make an autotest for this somehow?

Think so, should be possible to make a subclass of QGraphicsWebView and see if focusInEvent() is received after showing the view. I'll see if I can get a test up and running.

Would be cool if you could do a test with multiple scenes.

[Kenneth Rohde Christiansen]

It would be really cool if you could make a similar patch for our WebKit2 port.

A test where you have a view visible and changing the scene you mean? Shouldn't be hard.

I'll see if I can find some information about how to start hacking on that.

Ouch, an event-filter on the scene. That sounds _really_ evil. IMHO we should roll out the patch.

I think the bug is actually in QtTestBrowser, in WebViewGraphicsBased::WebViewGraphicsBased, which should make the m_item the focus item.

Indeed. My first solution was too complex for this.
