Bug 49953 – [Qt] Focus rings are ugly, rects should be united instead of drawn individually

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Andreas Kling]

We currently draw each rectangle individually in GraphicsContext::drawFocusRing(Vector<IntRect>, ...)

We should join the rects and paint them as a bounding path, like other ports do.

Screenshots from QtWebKit and Chromium coming.

Thank you Andreas!
Antonio Gomes & I were talking about exactly the same thing. The focus ring in Qt is ugly and hard to see in many cases.

Since the addition of support for color and width for focus rings in <http://trac.webkit.org/changeset/73361>, QtWebKit trunk looks slightly ridiculous (see screenshot.)

Agreed. I already offered to take over this bug :-)

Go for it, I doubt Reni was going to work on this anytime soon. :-)

Patch.

Create a QPainterPath and add to it the focus rects, one at a time.
Combine the 2 drawFocusRing functions into one function drawFocusRingForPath.

Kling, the size of this patch is due to the images from the tests, code changes are very small :-)

It is much better now, but still looks bad. The focus ring could be more thin. Yael, are you on it or plan to?

I have been trying to make it look better, but I don't have a solution yet.

Ideally, we should use a gradient to draw the focus ring, like the mac port does. See an example in <http://imagepaste.nullnetwork.net/viewimage.php?id=1591>.
When I tried to use Qt's radial gradient, I got the result in <http://imagepaste.nullnetwork.net/viewimage.php?id=1590>, which is not what I wanted. I'll be happy to get some help fixing it.

Ok. Is there a follow up filed? Should we reopen?

I think we need a new bug. This bug was filed before I added support for outline-width, which caused this problem.
