Some gtk specific tools and widgets
* rec2gtk : put record array in GTK treeview - requires gtk
Example usage
import matplotlib.mlab as mlab
import mpl_toolkits.gtktools as gtktools
r = mlab.csv2rec('somefile.csv', checkrows=0)
formatd = dict(
weight = mlab.FormatFloat(2),
change = mlab.FormatPercent(2),
cost = mlab.FormatThousands(2),
)
exceltools.rec2excel(r, 'test.xls', formatd=formatd)
mlab.rec2csv(r, 'test.csv', formatd=formatd)
import gtk
scroll = gtktools.rec2gtk(r, formatd=formatd)
win = gtk.Window()
win.set_size_request(600,800)
win.add(scroll)
win.show_all()

formatd is a dictionary mapping dtype name -> mlab.Format instances
This function creates a SortedStringsScrolledWindow (derived
from gtk.ScrolledWindow) and returns it. if autowin is True,
a gtk.Window is created, attached to the
SortedStringsScrolledWindow instance, shown and returned. If
autowin=False, the caller is responsible for adding the
SortedStringsScrolledWindow instance to a gtk widget and
showing it.
