Summary [Qt] Combobox doesn't close when scrolling in graphicsbased mode

Reported 2010-05-12 13:05:17 PDT
Created attachment 55890 [details] Screenshot showing the issue The combobox in graphics mode is using a proxy widget and thus doesn't seem to be notified when the proxy widget looses focus, resulting in wrong rendering.

Sounds like a Qt (QGraphicsView) bug... Can you try to make a Qt-only testcase for it and report it upstream?

Alexis, have you seen something like this before? Could it be a QGraphicsProxyWidget problem?

I think we have similar bug, but not exactly the same: https://bugs.webkit.org/show_bug.cgi?id=40082

Comment on attachment 60003 [details] Patch v2 Fine with me. Girish made the original patch because it was needed for SecondLife, maybe you should notify him.

No but I had a similar problem which this patch corrects. The context menu bug feels like there is a graphicsView->mapFromScene(graphicsWebView->mapToScene(pos)) missing somewhere.

Comment on attachment 60003 [details] Patch v2 I think that this patch should not go in. After having a look I saw that QtAbstractWebPopup is not exposed in the API, and this patch would change the containment of a QGraphicsWebView inside a scene like SecondLife probably needed. To use a QWidget combo box popup we would need to know if the developer wants to use QGraphicsWebView for its advantages (like accelerated compositing, tiling) or because he wants it inside a QGraphicsScene. Until we have a flag or a class that separate these two cases I think we should keep this behavior for popups. I have another fix (mostly in Qt) for this bug and I'll push it when possible.

Created attachment 60130 [details] Patch (complementary to the one in Qt) The patch in Qt will close the popop on wheel event like for QWidgets outside a graphic scene. This patch make sure that we catch the popup hide event since the popup is directly closed by the QGraphicsScene.

I realize this bug is closed but the reason to use a proxy widget is so that the scene can render the popup when using QGraphicsScene::render(). With a QWidget combo box, the popup simply won't render since it's not part of the scene.
