# Hello world example. Doesn't depend on any third party GUI framework.

# Tested with CEF Python v57.0+.

# ==== High DPI support on Windows ====

# To enable DPI awareness on Windows you have to either embed DPI aware manifest

# in your executable created with pyinstaller or change python.exe properties manually:

# Compatibility > High DPI scaling override > Application.

# Setting DPI awareness programmatically via a call to cef.DpiAware.EnableHighDpiSupport

# is problematic in Python, may not work and can cause display glitches.
