[Plplot-devel] Re: plgetpos transformation (was valgrind)

[Alan W. I. <ir...@be...>]

I would appreciate further discussion of one aspect of the plTranslateCursor
code.

It goes through a reversed list of windows (I assume these are sub-windows?)
and for the first one where the cursor is inside the sub-window it does the
transformation and returns.

If I have this interpretation right, then it looks like the pyqt group's
plgetpos using data in the PLStream struct won't really work since on a
page with subwindowing, the world coordinates can vary wildly form sub-window
to sub-window (e.g., example 1), and their code doesn't take account of
this.  So my guess is they are going to be forced (by example 1) to go
to the plTranslateCursor type of transformation.

Do you agree?

Alan
