Positioning frames on screen

[Lestat BZH]

Hi there,

I wrote a code that chains multiple frames containing widgets on screen with TkInter, and almost everything is fine except:
the windows created with TkInter seem to be randomly placed by Windows. I would rather have them always popping at the same location on screen, but I really don't know how to do that...

Someone may have the answer :)
Thanks in advance

Use .geometry() for the Toplevel http://www.tkdocs.com/tutorial/windows.html

Ok, thanks, I didn't know "geometry" could do that ^^

So, in my code I have this for one of my window:

class Starting_window(Tkinter.Tk):	#First instruction window
	def __init__(self,parent):
		Tkinter.Tk.__init__(self,parent)
		self.parent = parent
		self.initialize()
		self.geometry("350x270")

So, if I want this to be placed close to the top left of the screen, I have to modify the last line above this way:

class Starting_window(Tkinter.Tk):	#First instruction window
	def __init__(self,parent):
		Tkinter.Tk.__init__(self,parent)
		self.parent = parent
		self.initialize()
		self.geometry("350x270-5+5")

Right?

The geometry string "350x270-5+5" will place the right side of the window 5 pixels from the right side of the screen. If you want your window near the upper left corner, use "350x270+5+ 5".

Thanks, you're great, it's working fine :)

I even found a way to center my windows:

class Starting_window(Tkinter.Tk):	#First instruction window
	def __init__(self, parent):
		Tkinter.Tk.__init__(self, parent)
		self.parent = parent
		self.initialize()
		self.geometry("350x270+%d+%d" %((self.winfo_screenwidth() - 350) / 2,
										(self.winfo_screenheight() - 270) / 2))

	def initialize(self):
		self.grid()
		texte = Tkinter.Label(self, text = input_text, fg = "white",
																	bg = "blue")
		texte.grid(column = 0, row = 0, sticky = 'N')
		button_continue = Tkinter.Button(self, text = u"Continue",
										command = self.OnButtonClickContinue)
		button_continue.grid(column = 0, row = 5, sticky = 'W')
		button_kill = Tkinter.Button(self, text = u"Quit",
											command = self.OnButtonClickKill)
		button_kill.grid(column = 0, row = 5, sticky = 'E')
		self.resizable(False, False)

	def OnButtonClickContinue(self):
		input_values.completion = 1
		self.destroy()
		app = First_Variable_Choice(None)
		app.title('DetectorCL - Testing Tool')
		
	def OnButtonClickKill(self):
		input_values.completion = 0
		self.destroy()

Much better this way, thanks all :)
