KDE Makes More Progress On HiDPI Support

KDE developer David Edmundson has made some more progress with improving the high DPI display experience with KDE applications.

David has been using a high resolution laptop to work on his latest round of KDE optimizations. The Qt device pixel ratio can now be controlled from a configuration file and there's a UI in the works to allow the user to easily modify the QT_DEVICE_PIXEL_RATIO value from the GUI world. Besides that work, Edmundson has also been working on high resolution image support inside various KDE applications.


"For some applications supporting high DPI has been easy. It is a single one line in KWrite, and suddenly all icons look spot on with no regressions. For applications such as Dolphin which do a lot more graphical tasks, this has not been so trivial. There are a lot of images involved, and a lot of complicated code around caching these which conflicts with the high resolution support without some further work," David explained.

David also wrote in today's blog post, "We also have a problem that Qt4 applications do not support device independent pixels. There are still many applications without a frameworks release even in the upcoming 15.04 applications release. Even in the next applications release in 15.08 August we are still unlikely to see a released PIM stack. Is it a good idea to add an option into our UIs that improves some applications at the cost of consistency? It's not an easy answer."
