Tk uses native dialogs on Windows and Mac, so if you don't like the 
native implementation, you have to roll your own, or use the Unix 
version. Not sure how to access the Unix version from Tkinter.

Hi all,

I have an application that it requires to plot the result from some 
heavy calculation. Python is slow, so I am writing the calculation part 
as a C++ extension for python. Is it possible to draw directly to a 
Canvas opened from Tkinter from the C++ extension, in order to avoid 
useless transfer of data from C++ to python to tkinter?

Hello,

I need to make a GUI which has a fixed window size approx 390 (width) X 6020
(height)

It needs to have a fileMenu containing "File" "About" "Exit". In the "file"
menu it needs a menuItem called "new route".

When you click on "new route" it needs to display a new window with a
listBox.. When a user selects an item from the list box and clicks OK - it
should pass this value to the original window.

The difficulty here is that the main body of the GUI window, needs to
display an image BUT it needs to be an image that is able to be drawed on.

Below is my code for drawing on the image....... It is an EXAMPLE - but i
need it like this i.e. by importing the ImageDraw library.

# Do the proper imports for this script
from Tkinter import *
import os, sys
import Image
import ImageDraw
# Load the image
try:
im = Image.open("C:\Documents and Settings\Administrator\Desktop\mm.gif")
except:
print "Unable to load image"
exit(1)
# Get a drawing surface for the image
draw = ImageDraw.Draw(im)
# Draw the circle
#draw.ellipse((0,0)+im.size)
# Draw the line
#draw.line((0,0)+im.size)
# and show off the result
draw.line((0, 0) + (0,55), fill=000, width=22)
draw.text((50, 50), "hey")
im.show()

Below is my code for the list box example......

from Tkinter import *
class ListBoxTest :
def __init__(self) :
self.root = Tk()
self.list_box_1 = Listbox(self.root)
self.list_box_1.pack()
self.delete_button = Button(self.root, text="Delete",
command=self.DeleteSelection)
self.delete_button.pack()
def DeleteSelection(self) :
items = self.list_box_1.curselection()
pos = 0
for i in items :
idx = int(i) - pos
self.list_box_1.delete( idx,idx )
pos = pos + 1
def Show(self) :
for i in range(0, 10) :
s = "Item " + str(i)
self.list_box_1.insert( END,s )
self.root.mainloop()
lbt=ListBoxTest()
lbt.Show()

Below is my code for the Canvas and Window BUT the canvas does not hold an
image I have drew on........

from Tkinter import *

class AppUI(Frame):

def __init__(self, master=None):
Frame.__init__(self, master, relief=SUNKEN, bd=2)

self.menubar = Menu(self)

menu = Menu(self.menubar, tearoff=0)
self.menubar.add_cascade(label="File", menu=menu)
menu.add_command(label="New")

menu = Menu(self.menubar, tearoff=0)
self.menubar.add_cascade(label="Edit", menu=menu)
menu.add_command(label="Cut")
menu.add_command(label="Copy")
menu.add_command(label="Paste")

try:
self.master.config(menu=self.menubar)
except AttributeError:
# master is a toplevel window (Python 1.4/Tkinter 1.63)
self.master.tk.call(master, "config", "-menu", self.menubar)

canvas = Canvas(width = 300, height = 200, bg = 'white')
canvas.pack(expand = YES, fill = BOTH)

gif1 = PhotoImage(file = 'mm.gif')
canvas.create_image(50, 10, image = gif1, anchor = NW)
canvas.pack()

root = Tk()

app = AppUI(root)
app.pack()

root.mainloop()

---- Is there anyone here who can put these elements together and maybe make
this GUI for me? I'm really stuck and as you can see by the code examples I
have gave this a shot, but I don't know how to finish it off - If someone
can do this for me - it would be great as I can look at the code and learn.

Hi Thomas,

  An image will be garbage collected if thee is no pointer
to the variable holding the image.

You thus need to change the following lines of code:

    self.gif1 = PhotoImage(file = 'mm.gif')
    canvas.create_image(50, 10, image = self.gif1, anchor = NW)

(by making the gif1 variable a permanent aspect of the AppUI
object, it won't be garbage collected)

Hi all,

  Under Windows with python 2.6.4 Tkinter 8.5

  I am trying to find a way to restore exactly the same scroll
position in a scrolled text widget, after deleting all text and
re-inserting the same text.

Given a text widget in self.text, I can do the following:

        # record the index of the top visible  line in the text widget
        topidx=self.text.index(" <at> 0,0")

        # redraw the text
        self.renew()

        # Restore the scroll
        self.text.see(topidx)

However, "see" does not put this line index at the top
of the text widget, but rather some number of lines below
(unless it was already visible, in which case it stays where it was)

Is there an easy way to put a definite line at the top of a scrolled
text widget?

I would use

   self.text.yview(MOVETO, fraction)

...but I cannot find out at what fraction of the window this line is!
(my lines are of variable height, so I cannot simply multiply line height).

Any other ideas?

Mick

Thomas,

A post which in essence says "please write my application for me" is pretty much a guaranteed way to annoy
people - who are generally busy writing their own applications - or to simply be ignored.

A better approach would be to figure out what part of Tkinter isn't working as you expect, construct the
*smallest* possible code that demonstrates the problem (hint: this will NOT be an entire section of your
application) and submit that to this list.

Cheers

Cam

I think it should work like this:

>>> from ScrolledText import ScrolledText
>>> s=ScrolledText()
>>> s.pack(fill='both', expand=1)
>>> s.insert('end', some_text)
>>> first, last = s.yview()
>>> s.delete(1.0, 'end')
>>> s.insert('end', some_text)
>>> s.yview_moveto(first)

I hope this helps

Michael
