title: Scaling of Tkinter GUI in 4k (3840*2160) resolution?
body: <p>I use LinuxMint 17.3 Cinnamon in VirtualBox, 1920*1080 resolution is used in this machine, the Hi-DPI option is turned on. The host machine is Windows 10, with 3840*2160 resolution.<br/>
  Despite turning on Hi-DPI option in LinuxMint, some applications become to look good for comfortable work, in terms of scaling, but python-tk GUI (python2) hasn't been changed - font size is tiny, changing of Font options in Cinnamon doesn't change fonts in tk. Is there any way to scale correctly already written tk GUI applications?</p>
