[Tkinter-discuss] 4k HiDPI displays and tkinter [cont]

[Vasilis Vlachoudis]

Hi Michael,

no I am using the default fonts.
What is different is the I have set a high DPI for the X-server to match the screen resolution.

I saw in the page
https://www.tcl.tk/man/tcl/TkCmd/ttk_treeview.html

under "Styling Options'
there is parameter to set the -rowheight
that needs to be defined as

ttk::style configure Treeview \
     -rowheight [expr {[font metrics font -linespace] + 2}]

however I could not find how to call this command, and when
If I do the following

style = ttk.Style()
style.configure("Treeview", rowheight="30")

it works, but it is not dynamic with the font size/dpi

Vasilis

are you possibly using a point-sized font? If yes, maybe there is some
dpi issue again?
