Hi guys,
I'm new to the list; actually just found out it existed. I'm fairly new to
python and programming, and I'm just beginning with Tkinter. I'm trying to
layout my page, and I'm having problems understanding the action of some of
the frames. I actually posted about this on a general python help message
board and someone suggested that I repost it to this list. My question is
somewhat complex, so in attempt to simplify things a bit I am posting part
of a response I posted in a thread on the previous message board. Hopefully
this fully describes my problem:
When I specify dimensions of the text boxes, no matter how high or low, the
enclosing frame seems to adjust to fit the new boxes. So, for instance, if I
try inserting a text widget in leftframe with dimensions 1x1, leftframe
shrinks down to 1x1. If I make the text widget 100x100, leftframe takes that
size. What I want, and what seems like should be happening, is if I have
leftframe which is 500X500 pixels, and I create a text box wit effective
dimensions of 200X200 (I understand that text widgets use lines as
dimensions), the text box should take up a little less than half of
leftframe, with leftframe remaining 500X500 pixels. Instead, leftframe is
shrinking down to become 200X200, and I can't figure out why. After a while
I tried removing the text boxes and I got the same problem. I think maybe
this code will better illustrate the problem. This first set of code is the
totally stripped down version, and you can see leftframe in white on the
left, and rightframe in blue on the right.
from Tkinter import *
import tkFileDialog,tkSimpleDialog,tkMessageBox
WINDOWWIDTH=500
WINDOWHEIGHT=500
TITLEFONT = ("Courier",12,"normal")
HEADINGFONT = ("Helvetica",9,"bold")
class App:
def __init__ (self,master):
self.window = Frame(master,width=WINDOWWIDTH,height=WINDOWHEIGHT)
self.window.pack(expand=YES, fill=BOTH)
self.master= master
self.currentfeeds = []
#Create frame to contain all others
self.display=Frame(self.window,width=WINDOWWIDTH,height=WINDOWHEIGHT,
bg='black')
self.display.pack()
#Create widgets
self.createwidgets()
def createwidgets(self):
# create a top menu
self.addMenu(self.master)
self.addToolbar()
self.leftframe=Frame(self.display,
width=WINDOWWIDTH/3,height=WINDOWHEIGHT, bg='white')
self.rightframe=Frame(self.display,
width=2*WINDOWWIDTH/3,height=WINDOWHEIGHT, bg='blue')
self.leftframe.pack(side="left", expand="yes", fill="x")
self.rightframe.pack(side="left", expand="yes", fill="x")
def addMenu(self,master):
self.menu = Menu(self.window)
master.config(menu=self.menu)
self.filemenu = Menu(self.menu)
def addToolbar(self):
self.toolbar = Frame(self.display)
self.toolbar.pack(side='top',expand="yes", fill="x")
root=Tk()
app=App(root)
root.mainloop()
You could have simplified a lot more actually. (*)
Next, if I try to pack ANYTHING inside rightframe, it shrinks down to size
and totally distorts my screen dimensions. Here is the exact same code,
adding a label widget in self.rightframe. It completely shrinks rightframe
and distorts the screen dimensions. Does my question make sense now?
from Tkinter import *
import tkFileDialog,tkSimpleDialog,tkMessageBox
WINDOWWIDTH=500
WINDOWHEIGHT=500
TITLEFONT = ("Courier",12,"normal")
HEADINGFONT = ("Helvetica",9,"bold")
class App:
def __init__ (self,master):
self.window = Frame(master,width=WINDOWWIDTH,height=WINDOWHEIGHT)
self.window.pack(expand=YES, fill=BOTH)
self.master= master
self.currentfeeds = []
#Create frame to contain all others
self.display=Frame(self.window,width=WINDOWWIDTH,height=WINDOWHEIGHT,
bg='black')
self.display.pack()
#Create widgets
self.createwidgets()
def createwidgets(self):
# create a top menu
self.addMenu(self.master)
self.addToolbar()
self.leftframe=Frame(self.display,
width=WINDOWWIDTH/3,height=WINDOWHEIGHT, bg='white')
self.rightframe=Frame(self.display,
width=2*WINDOWWIDTH/3,height=WINDOWHEIGHT, bg='blue')
self.leftframe.pack(side="left", expand="yes", fill="x")
self.rightframe.pack(side="left", expand="yes", fill="x")
self.label=Label(self.rightframe,text='Current
story',font=HEADINGFONT).pack(side='top')
def addMenu(self,master):
self.menu = Menu(self.window)
master.config(menu=self.menu)
self.filemenu = Menu(self.menu)
def addToolbar(self):
self.toolbar = Frame(self.display)
self.toolbar.pack(side='top',expand="yes", fill="x")
root=Tk()
app=App(root)
root.mainloop()
See (*).
Thinking about your problem for a moment, it is not really a problem.
You are not supposed to develop GUI applications with a completely
fixed layout, because people that will use the GUI app will adjust it
according to their preferences. It is very very bad to layout widgets
like that, and harder too. You should rethink about the problem you
are trying to solve.
Said that, it is possibly to manually position things without using
pack or grid, that is, use place for that. But.. reconsider what you
are doing. Nevertheless, follows a sample that demonstrate what you
seems to want right now:
from Tkinter import Tk, Frame, Label
WINDOWWIDTH = 500
WINDOWHEIGHT = 500
class App:
def __init__ (self):
#Create frame to contain all others
self.display = Frame(width=WINDOWWIDTH, height=WINDOWHEIGHT)
self.display.pack()
#Create widgets
self.createwidgets()
def createwidgets(self):
self.leftframe=Frame(self.display, width=WINDOWWIDTH / 3,
height=WINDOWHEIGHT, bg='red')
self.rightframe=Frame(self.display, width=2 * WINDOWWIDTH / 3,
height=WINDOWHEIGHT, bg='blue')
self.leftframe.pack(side="left", expand=True, fill="x")
self.rightframe.pack(side="left", expand=True, fill="x")
label = Label(self.rightframe, text='test')
label.place(x=200, y=200)
root = Tk()
app = App()
root.mainloop()
It is possible that you are after paned windows, that is perfectly
understandable then. For that, take a look at Tkinter.PanedWindow
