I noticed that the width argument for the Tkinter entry widget is in characters, not pixels. 
Is it possible to adjust the width in pixels?
You cannot specify the width in pixels using the '-width' option, but there are ways to accomplish the same thing. For example, you could pack an entry in a frame that has no border, turn off geometry propagation on the frame, then set the width of the frame in pixels.
How do I set the width of an Tkinter Entry widget in pixels?
