I am currently looking for a possibility to display PDF Files inside a Tkinter application (displaying them e.g. in a Frame widget or similar).

Is there already a solution for this problem?

I already searched SO, used ddg an others but did not find anything for that purpose. Only thing I found was how to print the contents of a tk.Canvas to PDF - is there a way to load a PDF into a Canvas?
