raskol · 04-04-2008, 07:05 PM

Buttons shrink to fit the symbol/text u put on it. well i dont want that it looks ugly. how do i set the same size for all the buttons?
i thought it was row/columnspan at first but it doesnt seem to work.

Code:

#! /usr/bin/env python
from Tkinter import *
import tkMessageBox

class GUIFramework(Frame):
    """This is the GUI"""
    
    def __init__(self,master=None):
        """Initialize yourself"""
        
        """Initialise the base class"""
        Frame.__init__(self,master)
        
        """Set the Window Title"""
        self.master.title("Calculator")
        
        """Display the main window"
        with a little bit of padding"""
        self.grid(padx=10,pady=10)
        self.CreateWidgets()
       
    def CreateWidgets(self):

        self.btnDisplay = Button(self, text="1", state=DISABLED)
        self.btnDisplay.grid(row=0, column=0, padx=5, pady=5)

        self.btnDisplay = Button(self, text="2", state=DISABLED)
        self.btnDisplay.grid(row=0, column=1, padx=5, pady=5)

        self.btnDisplay = Button(self, text="3", state=DISABLED)
        self.btnDisplay.grid(row=0, column=2, padx=5, pady=5)

        self.btnDisplay = Button(self, text="+", state=DISABLED)
        self.btnDisplay.grid(row=0, column=3, padx=5, pady=5)

        self.btnDisplay = Button(self, text="4", state=DISABLED)
        self.btnDisplay.grid(row=1, column=0, padx=5, pady=5)

        self.btnDisplay = Button(self, text="5", state=DISABLED)
        self.btnDisplay.grid(row=1, column=1, padx=5, pady=5)

        self.btnDisplay = Button(self, text="6", state=DISABLED)
        self.btnDisplay.grid(row=1, column=2, padx=5, pady=5)

        self.btnDisplay = Button(self, text="-", state=DISABLED)
        self.btnDisplay.grid(row=1, column=3, padx=5, pady=5)

        self.btnDisplay = Button(self, text="7", state=DISABLED)
        self.btnDisplay.grid(row=2, column=0, padx=5, pady=5)

        self.btnDisplay = Button(self, text="8", state=DISABLED)
        self.btnDisplay.grid(row=2, column=1, padx=5, pady=5)

        self.btnDisplay = Button(self, text="9", state=DISABLED)
        self.btnDisplay.grid(row=2, column=2, padx=5, pady=5)

        self.btnDisplay = Button(self, text="*", state=DISABLED)
        self.btnDisplay.grid(row=2, column=3, padx=5, pady=5)

        self.btnDisplay = Button(self, text="0", state=DISABLED)
        self.btnDisplay.grid(row=3, column=0, padx=5, pady=5)

        self.btnDisplay = Button(self, text="C", state=DISABLED)
        self.btnDisplay.grid(row=3, column=1, padx=5, pady=5)

        self.btnDisplay = Button(self, text="r", state=DISABLED)
        self.btnDisplay.grid(row=3, column=2, padx=5, pady=5)        

        self.btnDisplay = Button(self, text="/", state=DISABLED)
        self.btnDisplay.grid(row=3, column=3, padx=5, pady=5)        
        
    #def Display(self):
        
                
if __name__ == "__main__":
    guiFrame = GUIFramework()
    guiFrame.mainloop()

I have used Tcl/Tk, so I am not sure this applies to your Tk environment as well.

You can stretch widgets to have them fit in a grid, using the sticky attribute. You can specify where you want your widget to stick to, and 'we' (west east) should make it stick to both sides of the grid.

In short, define a grid, and place your buttons inside the grid and make them stick to both the right and left side.
