Hi Thiego,
Sorry didn¹t mean to jump the gun. Still a bit new to the Qt process. Just
to clarify, the module is not yet part of ³Qt proper². I guess a more
correct term for it would have been ³a playground type of preview of a
potential new Qt module². Accepting it as new module in Qt proper shoul
Hi Gunnar,
Thanks for the comments, quite a lot to go through, but let me answer the
simplest and shortest ones first.

True, should say WebGL like, I have a list of differences on API level
that I¹ve maintained when implementing the context, b

Just for the sake of Qt Project procedures:

Hi Pasi,
I'm super happy that we are finally getting support for WebGL in QML, so thanks
for picking this up.
I have some suggestions for further improvement though:
We have a couple of items that implement QSGTextureProvider as an API. It would
be really nice if we could use these directly as

Actually, on second thought, given the (desirable) conversion to
RestrictedBool, I'd stay with isNull() after all.

In current terms, yes. I like Thiago's implicit suggestion (in the change
comments) to use isEmpty(), though (instead of isNull()).

Hello!
I've started working on a QOptional class
(https://codereview.qt-project.org/#/c/92006/).
As Thiago mentioned in gerrit, there are some things to discuss.
First is a QVariant integration. I think, i should add:
1) template QVariant::QVariant(const QOptional &o); constructor
2) template Q
I don't think Phonon is a supported backend in Qt 5. You should
probably look into new "Qt Multimedia" framework. On Linux, this
framework relies on GStreamer (for other platforms, it has different
dependencies).

As part of Lars’s blog post some of you may have noticed that a new module
called QtCanvas3D became available at https://qt.gitorious.org/qt/qtcanvas3d
QtCanvas3D module is a lightweight implementation of a QML canvas component
that allows you to get a 3D context object that you can then us

Hello,
I recently ported application from Qt4 to Qt5 and I rewrote a bit the
audioplayer in it. Now it is using QtMultimedia instead of Phonon.
I noticed that mpc file are not read. I got this error: [Error: "Could
not decode stream."]
I installed some packages on my linux about musepack: libmpcd
Dear Thiago
As I have mentioned in QTBUG-40641, I think the root cause is the function
QDirectFbIntegration::initialize() was called two times. Since the Qtcore will
call it, the original code in
QDirectFbIntegrationPlugin::create() should be deleted. Do you think is it
reasonable?
