please help!
I can't find anything wrong (except the result ofc ;-)
This:
picfile = 'logo.gif'
pic = tk.PhotoImage(f ile=picfile, master=root)
canpic = cv.create_image (320, 240, image=pic) #cv is is a Tkinter
Canvas ofc
....works just fine, but when I put it in the event binding function, it
doesn't work,
it doesn't report any errors too, I'm sure the function went all the way
through
because I print the test-text at the end of the function... But it doesn't
show picture!
here's the entire program I wrote to test this out:
=============== =============== =============== ======
import Tkinter as tk, os
root = tk.Tk()
root.title = 'Picviewer'
###setting Listbox, Canvas
lb = tk.Listbox(root ,width =20, height=22)
lb.grid(column= 0, row=0, columnspan = 2)
cv = tk.Canvas(root, width=640, height=480, bg='white')
cv.grid(column= 2,row=0, rowspan=2)
###listing all .gifs in current working directory into the Listbox lb
cwd = os.getcwd()
filelista = os.listdir(cwd)
filelista.sort( )
for element in filelista:
if os.path.isfile( element) and '.gif' in element.lower() : lb.insert(
lb.size() ,element)
###Load-button bind function (showing picture) - the problem seems to be in
here somewhere I think
def putpic(event):
picfile = lb.selection_ge t()
pic = tk.PhotoImage(f ile=picfile, master=root)
canpic = cv.create_image (320, 240, image=pic)
###just to see what's going on
print str(picfile), "\n", str(pic), '\n', str(canpic)
###setting Load-button
load = tk.Button(root, text='Load', width=16)
load.bind('<But ton-1>', putpic)
load.grid(colum n=0, row=2, columnspan=2)
###Putting the logo image at start (more like test image at start - and it
works)
pic = tk.PhotoImage(f ile='logo.gif', master=root)
canpic = cv.create_image (320, 240, image=pic)
root.mainloop()
=============== =============== =============== ===
Maybe I just need a fresh pair of eyes, SOMEONE!
