Bug 44252 – QWebView::selectionChanged() is never emitted.

• Status: RESOLVED

Proposed fix - apply with patch -p0

QWebView has a selectionChanged() signal that is never emitted. I can't find a connect() to it in the source code, and setting a breakpoint on it, and QWebPage::selectionChanged(), the latter is hit while the former is not. It's rather obvious it's been forgotten to be connected :)

Looks sane, but you need a ChangeLog entry.
See http://trac.webkit.org/wiki/QtWebKitContrib for more information.

Looks ok. Please do the same for qgraphicswebview.cpp

QGraphicsWebView doesn't _have_ a selectionChanged() signal.
Maybe it should have one, but this report is about an _existing_ signal not being emitted.

Shouldn't you add the selectedText method as well? Please make sure that there are no other important selection methods missing?

Do we really want all these methods from QWebPage everywhere? Simon?

Good point. We possibly do not need them all connected to our view's. 

@marc, can not you make use of qwebpage's selectionChanged signal for your needs? If so, we could make it wont fix.

Btw, if we decide to go for it , you should combine both you previous patch with your newer patch in one.

The point of the original report was that QWebView::selectionChanged() _which exists and is documented_ is never emitted. You cannot remove that signal due to binary compatibility. You can, of course, obsolete it, but that's not my call to make (and not my task to implement). Either way, the solution can't be wontfix.

The second patch was a request from you guys. Take it or leave it, I don't care either way :)

Sorry, I've been through enough iterations of this patch already :)

Ok, I was wrong. r=me on your 3rd patch.

I do not think we need to have this signal to QGraphicsWebView. At least not without a public discussion on the mainling list about.

So lets go for your first approach.

Clearing revie on this patch, since I blindly requested for it.

If you still want that, lets discuss in the mailing list first.
