Do you know the main advantage of a Hummer? It can go pretty much everywhere, that’s why many armies are using it. If I talk about a Hummer it is because QGraphicsView can go pretty much everywhere too. Recently I was lucky enough to get a N900 (generously given by Jesper, don’t know for how […]

Working with clever people is great, but sometimes it comes back to bite you… This post is going to describe a great new feature in Qt and why we’re not going to implement it. 🙂 Over the last few months I’ve been toying with the idea of starting a new research project to develop a […]

Animations and state machine APIs in qt/master

Posted in Contributors, Git, Graphics, Kinetic, News, Qt

That’s right. This weekend we integrated the animation and state machine APIs (part of the Qt Kinetic project from the road map) in Qt’s master branch. They were both released as solutions before, and we’ve had a lot of feedback. The APIs have been through a bunch of reviews and iterations, and we’re really really […]

As part of Qt 4.5, we added QGraphicsItem::opacity. Which is great! But it doesn’t work as well as it could. We’re receiving a few comments about how this implementation could work better. Trouble is, in Qt 4.5 we only have two ways of rendering: direct, and indirect (“cached”, e.g., ItemCoordinateCache). And in order to apply […]

Posted in Graphics, Kinetic

Since I don’t want to take focus away from the 4.5.1 release, I’ll keep this short. We have now released an updated version of the Animation Framework solution. There are not so many visible changes to the animation classes – besides bug fixes we renamed QAbstractAnimation::iterationCount back to QAbstractAnimation::loopCount. (You don’t want to know how […]

New (and last?) QtAnimationFramework Solution

Published Friday March 27th, 2009 | 17 Comments on New (and last?) QtAnimationFramework Solution
Posted in Graphics, Kinetic, Labs

Following the good habit of release early, release often: here we have yet another qt solutions release: the QtAnimationFramework 2.2 (and since 2.1 it’s LGPL too o/) It’s mainly a refinement of the previous version, after a round of API review and incorporating all the feedback we got internally and externally. One main modification was […]

Animated Tiles

Posted in Graphics, Graphics View, KDE, Kinetic, Qt, Uncategorized

There’s a new example in the animations branch called “Animated Tiles”. It’s nothing very fancy, showing how to animate transitions between five defined states. But it does qualify for youtube material :-). If you want to access the code, visit the Kinetic labs page: http://labs.trolltech.com/page/Projects/Graphics/Kinetic Discussions are on #qt-kinetic on irc.freenode.net. Enjoy!
