[Tkinter-discuss] Differences on Mac and Windows

[Bhaskar Chaudhary]

Hello

Thanks Michael for the suggestions.

I tried inserting root.tk.call('tk', 'scaling', '-displayof', '.',
root.winfo_fpixels('1i') / 72.0) before adding any children to the
root.

I also tried using negative size value ("Times -8 bold") as suggested.

Neither of the two made any difference on a Mac. It still looks the
way as shown in attachment.

Any more suggestions on how to correct this issue will be really appreciated.

regards
Bhaskar Chaudhary
