Inside QImage (with a touch of Qt Quick and OpenGL)

QImage is the most common container for image data in Qt applications. Getting a QImage that contains the pixel data of an image loaded from a file is fairly self-explanatory: QImage img; img.load(“some_image.png”); This can then be used with QPainter, can be passed to widgets, and can also be utilized in Qt Quick scenes via […]

Qt Speech (Text to Speech) is here

Published Friday January 20th, 2017 | 14 Comments on Qt Speech (Text to Speech) is here
Posted in Accessibility, Dev Loop, News, Qt, Releases | Tags:

I’m happy that with Qt 5.8.0 we’ll have Qt Speech added as a new tech preview module. It took a while to get it in shape since the poor thing sometimes did not get the attention it deserved. We had trouble with some Android builds before that backend received proper care. Luckily there’s always the […]

Should you still be using QGraphicsView?

Published Thursday January 19th, 2017 | 36 Comments on Should you still be using QGraphicsView?
Posted in Dev Loop | Tags: , ,

There was a time when the Qt Graphics View Framework was seen as the solution to create modern user interfaces with Qt. Now that Qt Quick 2 has matured does the Graphics View Framework still have a place in Qt? At the Qt World Summit 2016 I gave a presentation entitled “The Curse of Choice.” […]

How to shoot yourself in the foot using only a scene graph (neat optimization trick inside)

I am trying to get into the habit of blogging more often, also about topics that may not warrant a white paper worth of text, but that may be interesting to some of you. For those of you who don’t know me, I am the maintainer of the text and font code in Qt, and recently I came across a curious customer case where the optimization mechanisms in the Qt Quick scene graph ended up doing more harm than good. I thought I would share the case with you, along with the work-around I ended up giving to the customer.

Which OpenGL implementation is my Qt Quick app using today?

Published Wednesday January 18th, 2017 | 4 Comments on Which OpenGL implementation is my Qt Quick app using today?
Posted in Declarative UI, Dev Loop, Embedded, Graphics, Performance, Qt Quick

Qt Quick-based user interfaces have traditionally been requiring OpenGL, quite unsurprisingly, since the foundation of it all, the Qt Quick 2 scenegraph, is designed exclusively with OpenGL ES 2.0 (the top of the line for mobile/embedded at the time) in mind. As you may have heard, the graphics API story is a bit more inclusive […]
