#17573 — Set initial size in TKinter

Hi,

I am quite newbie with Tkinter and I could not find the way to set the
size of the application. (I could find the method to make it
resizeable, though :-)) ) Any ideas, suggestions or links to
references are wellcome.

Here is my code:

from Tkinter import *

class Application(Frame):
    def say_hi(self):
	self.db += 1
        print 'hi there, -->> UG everyone! db = %d'%self.db

## TODO: meretezhetoseg
    def createWidgets(self):
      top = self.winfo_toplevel()
      top.rowconfigure(0,weight = 1)
      top.columnconfigure(0,weight = 1)
      self.rowconfigure(0,weight = 1)
      self.columnconfigure(0,weight = 1)
      self.QUIT = Button(self)
      self.QUIT["text"] = "QUIT"
      self.QUIT["fg"]   = "red"
      self.QUIT["command"] =  self.quit

      self.QUIT.pack({"side": "left"})

      self.hi_there = Button(self)
      self.hi_there["text"] = "Hello",
      self.hi_there["command"] = self.say_hi

      self.hi_there.pack({"side": "left"})

    def __init__(self, master=None):
        Frame.__init__(self, master)
        self.pack()
        self.createWidgets()
	self.db = 0

app = Application()
app.master.title('UG test')
app.mainloop()



Thx in advance...

Gabor

Probably due to this haphazard coding style; why would you name an
object "Application" that is an instance of Tkinter.Frame? That is
just going to confuse people, including yourself. Choosing proper
names is very important. Would you call a cat a hat? Or a dog a frog?
Also, why did you post so much non-applicable code? Here is what you
should have posted...

from Tkinter import *
#
app = Tk()
app.title('This is an App, not a frame or a button')
app.config(width=50, height=400)
#frame1 = Frame() # Proper Naming Example.
#frame2 = Frame() # Proper Naming Example.
app.mainloop()

Usually, the best way is to use the geometry method on instances of Tk 
or Toplevel. For example, if you have a variable named root which is the 
instance of Tk, you can do:

root.geometry('500x400')

This will make the window 500 pixels wide and 400 pixels high.

Where did you find an example code looking like this? This looks like 
veeeeeery old conventions for Tkinter programsŠ

For example, there's no need at all to do:

self.QUIT = Button(self)
self.QUIT["text"] = "QUIT"
self.QUIT["fg"]   = "red"
self.QUIT["command"] =  self.quit

This can be done in a single line:

self.QUIT = Button(self, text='QUIT', fg='red', command=self.quit)

The same goes for self.QUIT.pack({"side": "left"}). Nowadays, this is 
always written self.QUIT.pack(side="left").

And you should avoid creating only an instance of Frame. This actually 
creates a window, but it's a side-effect. Windows are created by 
instantiating Tk for the main one, and Toplevel for all others. Having 
only a Frame will cause problems later, for example if you want to add a 
menu to the window: You can do so on instances of Tk or Toplevel, but 
not on framesŠ

Two major problems with Tkinter exposed here.

1. The tutorials are VERY old and need to be updated. There needs to
be one, and preferably only one site for Tkinter tutorials. One that
is through and complete!

2. Tkinter is designed to "auto-magically" create a root window if the
user does not do so explicitly. This is a major flaw in the design of
Tkinter and needs to be removed yesterday!
