I have a couple short text files of quick reference info with links on the
desktop of a Raspberry Pi. When I need my memory refreshed, I just double
click the icon and it opens the file in the text editor. Since it is a
small 7" screen, I'd like this to open in a large font making it easier to
see. I don't know if there is a setting someplace or a switch I can add to
the launcher to do this.
Sometimes this can be accomplished via environment variables. I'm not
aware of any that can influence font sizes but I know that your problem
is typically identified as a "High DPI" issue and dealt with slightly
differently. If your text editor is Qt5 based, you can use a few
different variables to tell the app that the display is high DPI, and it
will scale everything accordingly.
QT_AUTO_SCREEN_SCALE_FACTOR
QT_SCALE_FACTOR
Using kwrite as an example
QT_SCALE_FACTOR=2 kwrite reference.txt
Will result in kwrite rendering twice as large as normal. This means
font sizes are increased as well. I'm sure GTK has an equivalent option
I just don't know what it is.
Ideas appreciated.
Michael
