I am trying to change the tk widgets to ttk, so I can globally correct them, e.g.root=tk.Tk()sb=ttk.Scrollbar(root)sb.pack(side=tk.RIGHT,fill=tk.Y)style=ttk.Style()style.configure("TScrollbar", width="10m")
However the width doesn't apply on the up/downarrows which they remain tiny.Where I can find the style options that I can change?
I've triedstyle.configure("TScrollbar.uparrow", width="10m")but doesn't work

Thank you all for the suggestions.I am going to try them.It would have been nice it tk had a global option to rescale everything by x2
Like in XFCE window manager

If you want to relate your screen distances to the size of characters in a font, then you could use font's `measure` method to compute pixel distances for em-s: https://github.com/thonny/thonny/blob/3f2607ff0b27ffedac9b24a107ea9fff5f6b1f1f/thonny/ui_utils.py#L2271
Best regards,

_______________________________________________Recently I've got a 4k laptop, and the first experience with linux and the 4k display is quite painful.I am still trying to tune it but for the moment my tkinter applications do not render nicely on such a display.- all widths like borderwidths, decorations, separators etc, set in pixels do not scale with the dpi settings. Could we use "mm" for their settings instead?- checkbox, radiobox the indicator appears tiny wrt the text
Is there a way to detect from tkinter a high res display and force a window scaling x2 for everything?What is your experience with such displays?
