root.geometry('600x400+0+0')
This makes a window of 600x400 pixels placed in the upper left corner of the
screen (+0+0 is the x- and y- offset;
both of the window size and the offset may be omitted, so you can use '600x400'
or '+0+0' as arguments for geometry()
as well).

Use instances of Toplevel() to create new windows as children of the root
(Tk()) window.

import tkFileDialog

should be set to an empty string.

text = Text(parent, font=('helvetica', '-12', 'normal'))# "negative" size ->
pixel size
or:
text.configure(font=('helvetica', '12', 'normal'))# "positive" size -> point
size
You can use any 3-tuple of the form (family, size, weight) as font descriptor;
if the requested font is not
found, the widget should fall back to some (probably ugly) default; tk
guarantees that at least 'times',
'helvetica' and 'courier' font families are available, the availability of
other fonts depends on your system.
I hope this helps

Re: [Tutor] Tkinter questions
I suggest looking at Introduction to Tkinter. http://www.pythonware.com/library/tkinter/introduction/index.htm HTH, Jacob Hello, I got some Tkinter questions that I need the answer for to complete a little project of mine: 1. How can I make the program to open in a X*Y sized window ? 2. How can I open another window from the first one (without closing it) ? 3. How can I add a file browser for my app (like the one you get when you press "Save as..." in windows apps) ? 4. How do I configure the font size on the Text widget (its realy huge, and I would like to change it to somthing like 12). 5. [OT] Do you know any web-sites that I can store my project at (like sourceforge and others) ? This is all for now :) Thanks in advence . -- 1.

Thank you !!
But I don't have the Image module...
Is it a part of the PIL toolkit ?
If not, where can I get it ?

Is it so hard if I only want to print plain text ?
Because I don't need anything special (only black text on white paper...).

Actually, I don't understand why you don't think its obvious to me (
must be because of my bad English =).
Thanks allot !

OK, I assume you mean code? :-) Here is an example modified from some experiments using the >>> prompt. It should work but might need a tweak along the way... from Tkinter import * state = 0 def changeIt(img, fname): global state if state == 0: img['file']='img0.gif' state = 1 else: img['file'] = 'img1.gif' state=0 top = Tk() # now create an image object and a button theImg = PhotoImage(file='spam.gif') b = Button(top, command = changeIt, image=theImg) b.pack() top.mainloop() # You'll need to provide your own image files :-) You can also see this in action with a Text box in my book chapter on building a games framework, the commented code for which is on the Useless Python website as hmgui.zip > > You mean print as in to a printer? > > Personally I tend to generate an HTML file and use the > > native OS Tools to print that.

HTML generation is just a case of creating a text file with appropriate HTML tags inserted. There are some modules around that can help. Printing the file then becomes a matter of finding the appropriate commands in your OS and using the os.system() call to execute them. For example Windows explorer uses this command to print HTML on my system: "D:\msoffice\OFFICE11\msohtmed.exe" /p %1 You'll need to look to find whats in use on yours... > > Define a full window?

Since that didn't fit your explanation I asked for clarity. Full screen is where a single window fills the currently available screen. > And why you refuse to use any program that insists on opening full screen ? > If it does then there must be a good reason for that... No, quite often its simply a fascist minded programmer who thinks his application is so important that I won't want to do anything else while it's running - games programmers are bad for this. But since I very rarely do only one thing at a time on my PC I want control of the window size thankyou very much - that's why I have a 21 inch monitor running at 1600x1200! There are very few valid situations for an application taking over the whole screen univited! Normally the user should be able to make that choice. (For example when editing video I usually do go full screen, but I decide, not the program!)

(Personally > I refuse to use any program that insists on opening full screen!) Full window or full screen is when the window of the program is all over the screen except the start bar (or whatever the blue line in the bottom of a windows xp called). And why you refuse to use any program that insists on opening full screen ? If it does then there must be a good reason for that... > If OTOH you mean that you don't want the DOS box in the background > thats easy, just rename the .py file to .pyw.
