I have a 27" 2560X1440 screen. For me:
>>> import tkinter; tkinter.Tk().tk.call('tk', 'scaling')
1.333...
I presume 3200x200 should be 3200x2000 and that the diagonal size is small
enough that the screen is a HiDPI screen, making tk's scaling above 1.4, so
that run.fix_scaling() adjusts font sizes.
I am not sure what you mean by 'scaling at 100%/200%' other than tk scaling <,
>= 1.4 or HiDPI no/yes, or how you changed the scaling. I grepped idlelib for
'scaling' and only found references to the function and the tk call.
In any case, tcl/tk does not properly support HiDPI screens. Serhiy Storchaka
contributed fix_scaling to make IDLE readable on a HiDPI Linux laptop. The 1.4
and .75 values are empirical. With help from Windows experts, I added the
SetProcessDpiAwareness call near the top of pyshell when a Windows user with a
HiDPI screen reported a problem on idledev. I believe that the call tells
Windows that IDLE already makes a scaling adjustment, so it should not also do
so.
zoomheight.zoom_height() restores by calling top.wm_geometry('').
https://www.tcl.tk/man/tcl8.6/TkCmd/wm.htm#M42 says
"If newGeometry is specified as an empty string then any existing
user-specified geometry for window is cancelled, and the window will revert to
the size requested internally by its widgets."
This works for normal screens but somehow not for your HiDPI Windows screen.
Can you do the print experiment I suggested previously?
I will experiment to see how much '22' needs to be increased for Windows to
accomodate the task bar. What is really needed is to determine the size and
orientation of the taskbar, or rather the remaining 'full-screen' height.
Serhiy, do you still have a HiDPI screen? If so, does Options => Zoom/Restore
Height work for you? Do Linux desktop managers have bottom panels or taskbars
that can cover part of a zoomed window?
Ignore any task bar over status bar issue.)
