I recently got a new embedded Linux device to decorate my desk. This is like my childhood dream. :-)) I’m incredibly happy to have the opportunity to work with such a range of awesome stuff at Trolltech. And working on embedded devices is like bringing me back to the days when I was hacking graphics […]

Accurate update regions for thin QGraphicsItems

Published Tuesday January 8th, 2008 | 10 Comments on Accurate update regions for thin QGraphicsItems
Posted in Graphics View, KDE, Labs, Painting, Qt

We’ve gotten reports about how Graphics View’s performance drops in one special (yet quite common) case. It’s the case when the item is fairly thin, flat, non-square, or simply sparse, where QGraphicsItem’s bounding rect generates something close to worst-case updates that cause repaints of areas that really haven’t changed. A very helpful customer showed me […]

Popups are a can of worms

Published Wednesday December 19th, 2007 | 10 Comments on Popups are a can of worms
Posted in Graphics View, KDE, Labs, Qt

Hm, that title sounds funny with no associated context. We’re implementing popup support in Graphics View. This is the result of an outstanding bug, or rather essential missing functionality, in the Widgets on Canvas project: support for embedded popups. I.e., popups that pop out of widgets that are embedded into a QGraphicsScene. Such as the […]

Noises from the crypt… (Widgets on Graphics View update)

Posted in Graphics View, KDE, Labs, Qt

Feature freeze for 4.4 is closing in. The offices in the dev department are awfully quiet. A bit… too quiet. The snippety-snapping sound of brilliant minds tapping in code, merging changes, polishing APIs, writing tests, reviewing patches. An incredible atmosphere, you would have to just be there to sense it. This is the period of […]

My first commit to KDE SVN

Published Monday September 10th, 2007 | 3 Comments on My first commit to KDE SVN
Posted in KDE, Qt

I just submitted a backport of QGraphicsItem::CacheMode to KDE4 SVN. The change is in Plasma::Widget, and gives Plasma the same speed boost that Qt 4.4’s QGraphicsItem eventually will have. For those interested, the change is also available in ftp://ftp.trolltech.com/qt/snapshots . Which is all of course completely irrelevant. The important thing is – it’s my first […]
