Question

I am working with buttons in Tkinter, Python.

The thing is when I click in one button the text of the button shakes. It might be a default behavior for this widget and I don’t know how to disable it and make it static.

I assume that you mean the relief change from raised to sunken when you click a button.

This is what I found on http://wiki.tcl.tk/1048 (click ‘Show Discussion’ to see it):

Unfortunately, the relief used when you click is hardcoded (as
‘sunken’), so you can’t configure it per-widget without hacking the Tk
internals for the binding for buttons.

So the simplest way around this would be to always make the button appear sunken

MyButton = Tkinter.Button(
    self.frame, 
    text = "Foobar", 
    command = self.foobar, 
    relief=Tkinter.SUNKEN
)

The disadvantage of that is that it might make the button look unresponsive.

You can also use a widget other than a button to be used as a clickable item (suggested by Joel Cornett). Here is a simple example with a label used as a button:

import Tkinter

class main:
        def __init__(self,root):
                # make a label with some space around the text
                self.lbl1 = Tkinter.Label(root,
                                          width = 16, height = 4,
                                          text = "Foobar")                
                self.lbl1.pack()

                # Call a function when lbl1 is clicked
                # <Button-1> means a left mouse button click
                self.lbl1.bind("<Button-1>", self.yadda)
                self.lbl1.bind("<Enter>", self.green)
                self.lbl1.bind("<Leave>", self.red)

        def yadda(self, event):
                self.lbl1.config(text="Clicked!")

        def green(self, event):
                self.lbl1.config(bg="green")

        def red(self,event):
                self.lbl1.config(bg="red")

if __name__ == "__main__":
    root = Tkinter.Tk()
    main(root)
    root.mainloop()
