I am a DJ who is blind. I use Serato DJ with a screen reader called Jaws. Serato DJ up to version 1.7.8 was designed with Carbon based code, but as of version 1.8.0, they have switched to QT based code. Ever since this has happened, Jaws is not able to read anything on the screen from Serato DJ. The people at Serato seem willing to help, but I don’t know how to direct them as I am not a programmer. Can anyone shed any light on how to enable some accessibility in order for Jaws to interact with Serato for me again? BTW, I believe they are using QT5.6 in there latest version of Serato DJ 1.9.3 THANKS! -------------- next part -------------- An HTML attachment was scrubbed...

There are many more details needed to allow us to even guess. Which Qt version, which platform, is it using Qt Widgets or Qt Quick for the UI. Without more detailed information there's nothing we can do. It would be great if the author of the software contacted us directly.

Why? Because many developers do not take AQT accessibility on their mind while developing. So typical situation would look as follows. Advanced user will launch not accessible QT app. He discovery, which QT IDE have been used to create it by searching inside specific program folder for QT libraryes. BLind user must locate and download whole QT specific IDE version and install it only to get one folder accessible from specific QT bundle. Why yxou can not simply add one zip archive to yours opensource QT site with all QT accessibility versions support files? Try to imagine, that no every body has time to install whole bundle only to copy one folder from one location to other. Yes, sure. You are doing yours bet to accessibility. Developers have chance to enable accessibility support for QT. But what if some developer do not do that? If you know some free and saccessible tool to extract some files from .msi packages, perfect. But I did not find something similar to do that. Next issue. Some QT application developers have fallen in love to static QT libraryes compilation. So they are statically embed QT libraryes inside machine code, inside .exe program. This can not be simply solved by unzipping .exer. Because QT libraryes are statically embedded inside some .exe format structures. And it is really not legal and easy for only advanced visually impaired user to use binary editor and modify .exe program to include accessible folder inside it. And I AM afraid, that if program is including statically compiled and embedded QT libs without accessibility support. user would not have A chance. Do you have some solution for that? Thank You very much for yours time. With kindness regards.

When using Qt5 + eglfs: i. Frame rate is around 56fps with 800 * 480 resolution display. ii.Frame rate is around 23fps with 1280 * 720 resolution display. iii.Frame rate is around 11fps with 1920 * 1080 resolution display. iv.CPU usage for above three cases is 99%. When using OpenGL: i. Frame rate is around 56fps with 800 * 480 1280 * 720 and 1920 * 1080 resolutions. ii.CPU usage slightly increases with resolution from around 10% to 18%. Whats affecting Frame rate in Qt5 and how can I increase the frame rate and improve CPU performance. I'm new to Qt as well as image processing. Kindly let me know your thoughts on this to solve. Thanks in advance. Regards, Ambika -------------- next part -------------- An HTML attachment was scrubbed...

Since Qt 5.4 accessibility is no longer a plugin bug got merged into the normal libraries (gui/widgets/quick). This way it is no longer possible to "forget" to deploy the accessibility libraries. There is still one problem that may hit you: developers may configure Qt with - no-accessibility to reduce library size or because they expect problems with the accessibility code. Another issue is Qt Quick. There it's generally easy to make applications accessible, but due to the low level nature of the basic building blocks, we cannot provide everything out of the box. When the Qt Quick Controls are used, accessibility support is there, but for applications that use custom drawing, we cannot do anything and the app developers need to set the right properties to enable working accessibility.
