Qcad GUI fonts

I am running Qcad Professional 13.8.1.0 on a Dell XPS laptop running Ubuntu Gnome 17.04. This laptop has a very high resolution screen running at 3480 x 2160 dpi. As a result, the fonts and icons are very small. Is there a way to scale the fonts and icons so I can keep the high resolution but have elements of the GUI large enough that I don't need magnifying glasses? Thanks.

Hi Andy - welcome to the QCAD forum.

Have you tried your luck with adjusting the settings below Application Preferences / Widgets like Toolbars?

You might also want to experiment with some Qt environment variables as specified at:
http://doc.qt.io/qt-5/highdpi.html#high ... port-in-qt

Code: Select all

QT_SCALE_FACTOR=1.2
or even

Code: Select all

QT_DEVICE_PIXEL_RATIO=2
One way to apply such environment variables only for QCAD is as follows:

Code: Select all

cd ~/opt/qcad-3.19.2-pro-linux-x86_64
QT_SCALE_FACTOR=1.2 ./qcad
or:

Code: Select all

cd ~/opt/qcad-3.19.2-pro-linux-x86_64
QT_DEVICE_PIXEL_RATIO=2 ./qcad

Thank you for your help. Changing the icon size in Application Preferences -> Toolbars did help with small icons, but nothing else including setting some Qt environment variables would change font sizes in the menus. In the end, I think this is an OS and video problem, not a Qcad problem because there are some other problems with icon and font sizes in other areas such as the boot screen. There are some settings in the Gnome Tweak Tool to set scaling factors and font sizes, but they do not affect Qcad's font sizes in the GUI. Maybe the best solution for me right now is to reduce my resolution a little and wait for a solution from Ubuntu.
Thanks again.
