I have been having trouble keeping the canvas/window from just expanding to the size of the information I am putting in the widget. I want to add scrollbars and limit the size of the canvas. This is for a popup window within a larger program. Here is my code
from Tkinter import *
import os
import tkMessageBox
class ClusterDialog(Toplevel):
def __init__(self, parent, displayClass, clusterInfo, title = None):
Toplevel.__init__(self, parent)
self.transient(parent)
#top = self.top = Toplevel(parent)
if title:
self.title(title)
#set parent
self.parent = parent
#set class
self.dClass = displayClass
#dictionary to store the header data in
self.clusterInfo = clusterInfo
#stores checkbox variables
self.varList = None
self.boxList = None
self.name = None
self.frameTopLevel = Frame(self,bd=2, width = 200,height=300)
self.frameTopLevel.pack()
self.buttonbox(self.frameTopLevel)
self.frame = Frame(self.frameTopLevel, width = 200,height=300)
#frame=Frame(root,width=300,height=300)
self.frame.grid(row=0,column=0)
self.frame.pack()
self.canvas=Canvas(self.frame,bg='#FFFFFF',width=300,height=300,scrollregion=(0,0,500,1000))
hbar = Scrollbar(self.frame,orient=HORIZONTAL)
hbar.pack(side=BOTTOM,fill=X)
hbar.config(command=self.canvas.xview)
vbar=Scrollbar(self.frame,orient=VERTICAL)
vbar.pack(side=RIGHT,fill=Y)
vbar.config(command=self.canvas.yview)
self.canvas.config(width=300,height=300)
self.canvas.config(xscrollcommand=hbar.set, yscrollcommand=vbar.set)
self.canvas.pack(side=LEFT,expand=True,fill=BOTH)
self.frame.config(height = 100)
self.body(self.canvas)
self.canvas.config(width=300,height=300)
self.grab_set()
Basically I am trying to create a topLevel frame that has a frame within it that contains the scrollbar and the canvas. the self.buttonbox(self.frameTopLevel) adds some buttons and the self.body(self.canvas) adds a bunch of checkboxes for the user to manipulate.
When i run this code my window always expands to the size of the screen and I can't scroll, although the scrollbars are present they do not do anything. Any help would be appreciated? I have been looking at other threads with similar problems but could not find a fix that would work.
Thanks
I just got your code to work however I had comment several things out so it did not populate the canvas with buttons. The window did not take up the entire screen though...
Window Size: Maybe try setting the geometry of the toplevel?
self.geometry("300x300+10+10") # numbers corresponding to [width]x[height]+[x offset]+[y offset]
Canvas: The problem is with placing widgets in the canvas. You might want to check this example out: effbot
