[Tkinter-discuss] When to use a Canvas vs. a Frame from a container perspective?

Hi Malcom,

  I use both Canvas and Text for scrollable containers.

I use the Canvas when I want pixel accurate placement.

I use a Text widget for more lazy placement (one can place
items after each other on a row, and start a new row with a "\n").
One can make spreadsheets by placing rows of entry widgets of
equal width.

However, with hundreds of widgets in a text widget, I find performance
