The code below produces a text window 60hx20w with a scroll bar. The
contents are something of a histogram of values from 0 to 255. If one tries
to copy the contents, Windows doesn't allow it. What needs to be done to
allow a copy and paste?
def ShowHistogram(self):
if not self.current_image:
return
if self.histogram:
self.histogram.destroy()
t = Toplevel( self.master )
t.title("Histogram")
t.bind( '<Destroy>', self.DestroyHistogram )
text = Text( t, height=60, width=20 )
scroll = Scrollbar(t, command=text.yview)
text.configure(yscrollcommand=scroll.set)
text.pack(side=LEFT, fill='both', expand=1)
scroll.pack(side=RIGHT, fill=Y)
self.histogram = t
hist = self.current_image.histogram()
for i in range(len(hist)):
msg = "%5d %6d\n" % (i,hist[i])
text.insert( END, msg )
