Re: [matplotlib-devel] Why num in manager?

[Thomas C. <tca...@gm...>]

I think that so long as you maintain the mapping of 'manager' to be 'gui
element holding the Figure' (rather than 'gui window holding figure')
numbering the managers should be ok.   That is, the tabs are the managers
and the multi-figure windows are a layer above the managers.

The notion of 'figure number' is very thoroughly a pyplot/figure manager
idea I am -1 on pushing that logic down in to the Figure class.
