A good rule of thumb is to never import pylab at the top level for
modules that need to be imported. In my own code, I often do
something like
def somefunc(figfunc):
fig = figfunc()
ax = fig.add_subplot(111)
ax.plot([1,2,3])
and then I can call it with
somefunc(pylab.figure)
or a custom func that generates a GUI embedded figure instance. Eg,
in my GTKApps, I have a functor like gtk_figure that returns a
function that creates a figure embedded in a GTK window.
In basemap, Jeffrey Whitaker does something like the following
def somefunc(ax=None):
if ax is None:
import pylab
ax = pylab.gca()
Here the pylab import is triggered only when the function is called
with default arguments. That way you can use it from GUI code without
triggering a pylab import like
somefunc(ax)
and from other code where you want pylab do do everything with
somefunc()
I'm afraid you have some cleanup to do..... Mixing pylab with
embedded GUI code is a recipe for pain and misery.
