Summary0013204: Unusably tiny tool icons on HiDPI screen on Ubuntu Unity desktop
DescriptionI am using Scribus on Ubuntu 15.04 x68_64, Unity desktop with a 13-inch 3200x1800 display. Unity interface scaling settings set to 2x.

While text appears in readable size, icons in the toolbar do not scale correctly, leaving the toolbar icons less than 2 millimetres in size on my screen.

The result is poor usability due to the need to squint and look very close to the monitor to be able to select a tool.

Expected result would be for icons to be of a usable size on a high-DPI screen automatically or for an icon size setting to be provided.

Thank you very much for Scribus!
Steps To Reproduce1. Use a 3200x1800 display
2. System Settings/All Settings/Display/Scale for menu and title bars: set to 2
3. Install Scribus 1.5.0 on Ubuntu:
  sudo add-apt-repository ppa:scribus/ppa
  sudo apt-get update
  sudo apt-get install scribus-ng
4. Start scribus-ng and look at toolbar of main window.

So does this mean that we need to generate a whole host of icons for higher res screens ?

From a usability point of view, just allowing the icons to be scaled with the desktop scaling setting (that may be a Unity rather than GTK thing) would do the trick I think. Of course hi res icons would look nicer but scaling may be a quicker fix.

This is also an issue on my 4k monitor. I agree that it is important for Scribus to add support for hidpi displays. Using scalable svg icons would be the best approach, but for now having an option to scale the UI icons up would already be a major improvement.

Hey folks, can you test how the new iconset looks like on a HiDPI screen ?
I think you will need to install trunk to test it.

Hi, thanks for the update. I've tested on Scribus Version 1.5.2.svn (scribus-trunk in Ubuntu 15.04) with a Dell XPS 13 HiDPI screen. It's certainly an improvement as the icons are crisper and therefore easier to distinguish.

They remain very small though and still require me to come very close to the screen to be able to select a tool button - it appears they do not scale with the rest of the desktop.

Glad that helped you some.

Qt HiDPI is still very new and a lot of opensource projects that use Qt are still scratching their heads trying to figure out how they've implemented it.

Created feature request 0013818 maybe a 3rd party dev would like to have a hand at it since the main devs do have their hands full.

Have you tried to set QT_AUTO_SCREEN_SCALE_FACTOR (Qt 5.6+) or QT_DEVICE_PIXEL_RATIO (Qt 5.4 and 5.5)?

Khaled, are you saying to assign to set them as env variables ?

Or in the code ?


2016-05-02 15:21


Environment variables. We c also set Qt::AA_EnableHighDpiScaling attribute to QApplication ( so that this environment variable is not needed, but I didn’t find the right place in the code to set it.
