Control location on screen where new windows open with graphics.py

I have a python program that deploys a windows via graphics.py. The initial window opened by the GraphWin class opens in the top left corner of the screen. Subsequent calls to GraphWin cascade from the upper left to the lower right.
I'd like to control the placement of each window. (Example: Have all the windows open in a grid-layout so I can create a dashboard.)

I think there is no such method in graphics.py right now.
Ref: The Book and webpage.
If you want to stick to using graphics.py, I suggest creating a dashboard by dividing a single window into different slots.
This option does exist in Tkinter library. Please refer to this answer for more information on that.

graphics.py doesn't provide a way for you to control the location of instances of its GraphWin class. However the fact that it's built on top of Python's Tk GUI toolkit module named tkinter means that sometimes you can work around its limitations by looking at its source code to see how things operate internally.
For example, here's a snippet of code from the module (version 5.0) showing the beginning of GraphWin class' definition from the graphics.py file:
class GraphWin(tk.Canvas):
"""A GraphWin is a toplevel window for displaying graphics."""
def __init__(self, title="Graphics Window",
width=200, height=200, autoflush=True):
assert type(title) == type(""), "Title must be a string"
master = tk.Toplevel(_root)
master.protocol("WM_DELETE_WINDOW", self.close)
tk.Canvas.__init__(self, master, width=width, height=height,
highlightthickness=0, bd=0)
self.master.title(title)
self.pack()
master.resizable(0,0)
self.foreground = "black"
self.items = []
self.mouseX = None
self.mouseY = None
self.bind("<Button-1>", self._onClick)
self.bind_all("<Key>", self._onKey)
self.height = int(height)
self.width = int(width)
self.autoflush = autoflush
self._mouseCallback = None
self.trans = None
self.closed = False
master.lift()
self.lastKey = ""
if autoflush: _root.update()
As you can see it's derived from a tkinter.Canvas widget which has an attribute named master which is a tkinter.Toplevel widget. It then initializes the Canvas base class and specifies the newly created Toplevel window as its parent.
The size and position of a Toplevel window can be controlled by calling its geometry() method as described in the linked documentation. This method expects to be passed a "geometry string" argument in a certain format ('wxh±x±y').
This mean you can take advantage of how this implementation detail in order to put it anywhere you want it and as well as resize if desired.
Here's an example of doing that:
from graphics import *
def main():
win = GraphWin("My Circle", 100, 100)
# Override size and position of the GraphWin.
w, h = 300, 300 # Width and height.
x, y = 500, 500 # Screen position.
win.master.geometry('%dx%d+%d+%d' % (w, h, x, y))
c = Circle(Point(50,50), 10)
c.draw(win)
win.getMouse() # pause for click in window
win.close()
if __name__ == '__main__':
main()

TreeView not working in Python Gtk3

So I have a GTk structure like:
Window()>
Grid()>
Label()
+
ScrolledWindow()>
TreeView()
+
Box()>
Button()
Everything works fine except th Scrolled Window is not Displayed correctly as seen below. I believe i am doing something wrong with the positioning or something.
I tried playing around with the positioning numbers but can't make it work.
My Code is:
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
index = None #Global variable holding the index of the final chosen subtitle
class window(Gtk.Window):
def __init__(self,data):
Gtk.Window.__init__(self, title="SubseekerV7 R&D")
self.set_border_width(5)
self.set_default_size(200, 400)
self.grid = Gtk.Grid()
self.grid.set_column_homogeneous(True)
self.grid.set_rowndex = None
heading_text = Gtk.Label()
heading_text.set_markup('<big><b>Choose Subtitle below</b></big>\n\n<i>Select a subtitle and press Download</i>\n')
scrolled_window = Gtk.ScrolledWindow()
scrolled_window.set_border_width(5)
scrolled_window.set_policy(Gtk.PolicyType.AUTOMATIC, Gtk.PolicyType.AUTOMATIC)
self.data_list_store = Gtk.ListStore(str,str,str, str)
for item in data:self.data_list_store.append(list(item[:4]))
self.data_tree_view = Gtk.TreeView(self.data_list_store)
for i, col_title in enumerate(["Serial","Name", "Language", "Score",]):
renderer = Gtk.CellRendererText()
column = Gtk.TreeViewColumn(col_title, renderer, text=i)
self.data_tree_view.append_column(column)
scrolled_window.add_with_viewport(self.data_tree_view);
buttons_box = Gtk.Box(orientation=Gtk.Orientation.HORIZONTAL,spacing=10)
#Button Declarations
self.submit_button = Gtk.Button(label="Download")
self.submit_button.connect("clicked", self.select_handle)
self.cancel_button = Gtk.Button(label="Cancel")
self.cancel_button.connect("clicked", lambda x:self.destroy())
#Adding buttons to button box
buttons_box.pack_start(self.submit_button, True , True , 0)
buttons_box.pack_start(self.cancel_button, True , True , 0)
self.grid.attach(heading_text, 0, 0, 4, 1)
self.grid.attach(scrolled_window,0,1,4,4)
self.grid.attach(buttons_box,0,5,4,1)
self.add(self.grid)
def select_handle(self,widget):
global index
tree_sel = self.data_tree_view.get_selection()
(tm, ti) = tree_sel.get_selected()
index = tm.get_value(ti, 0) #Modifying the index value to the currently selected index in treeview
self.destroy()
def main():
w = window([('a'*30,'b','c','d','e'),('p'*30,'q','r','s','t')]) #Bogus test dxata
w.connect("destroy", Gtk.main_quit)
w.show_all()
Gtk.main()
if __name__ == '__main__':main()

The reason is the widget layout behavior of GTK. Widgets do not take more space than required by default. A ScrolledWindow will become invisible as it shrinks to nothing (the size of the content does not matter).
This can be solved by forcing a specific size using set_size_request(width, height), or configure the widget to grow using set_property('expand', True).
Examples:
# Setting a fixed height
scrolled_window.set_size_request(-1, 200)
# Configure the scrolled window to expand
scrolled_window.set_property('expand', True)
An alternative to a Grid is to use a Box, and set expand=True in the pack_start function.

Canvas resize using Configure with Tkinter

I want to create a Board Game with Python and Tkinter
I want it to has a resize-function but I have two canvases for the GUI. First one is the square-Board (Spielfeld), the second one is the place where I want to add the control buttons for the player (Panel)
So if I want to resize my Board using <Configure> in my Master Window, it shall draw the Canvas with the New Size (self.FensterGroesse)
The If-Case is working well when I pass the else -function in resize
but if I run the Programm with the else function it resizes itself until its 1px big. Not just the canvas, the whole window.
I know the problem is the Panel being one third as high as the Board and when self.Panel.config sets the new size <Configure> is activated again.
But I dont know how I can have these two sanvases, one is a square, the other is a rectangle with the same widht and the square bit just 0.3*height
from Tkinter import *
class GUI:
def resize(self, event):
if event.height > (event.width*1.3):
self.FensterGroesse = event.width-2
else:
self.FensterGroesse = int(event.height/1.3)-2
self.Spielfeld.config(height=self.FensterGroesse, width=self.FensterGroesse)
self.Panel.config(height=self.FensterGroesse*0.3, width=self.FensterGroesse)
self.Spielfeld.pack()
self.Panel.pack()
def __init__(self):
self.FensterGroesse = 400
self.tkinter = __import__("Tkinter")
self.Master = self.tkinter.Tk()
self.Spielfeld = self.tkinter.Canvas(self.Master, height=self.FensterGroesse,
width=self.FensterGroesse, bg='#ffdead')
self.Panel = self.tkinter.Canvas(self.Master, height=self.FensterGroesse*0.3,
width=self.FensterGroesse, bg='brown')
self.Spielfeld.pack()
self.Panel.pack()
self.Master.bind("<Configure>", self.resize)
self.Master.mainloop()

Toplevel inside another Toplevel in tkinter [duplicate]

I'm not very good with tkinter of python, but i would like to know if theres a way to make a window inside a window, where that window cannot get out of the main window's bounds.
Heres my current code:
from tkinter import *
root = Tk()
root.title("Main Window")
root.geometry("640x480+100+100")
sub = Toplevel(root)
sub.title("Sub Window")
sub.geometry("320x240+125+125")
mainloop()
it would look like this:
I would like to know how I can isolate the Sub Window to keep it inside the main window even if i drag it out.
Thank you very much.

There is no built in method of doing so. However I've made a work around to accommodate it. Keep in mind that when trying to move the sub window outside the main window it isn't a smooth lock so it does get jumpy. Another issue is that because of the configure events I can't get the sub window position relative to main window to maintain it while moving the main window. Still working around that. However the code below does work and should be of use to you.
import tkinter as tk
root = tk.Tk()
root.title("Main Window")
root.geometry("640x480")
sub = tk.Toplevel(root)
sub.transient(root) #Keeps sub window on top of root
sub.title('Sub Window')
sub.minsize(320, 240)
sub.maxsize(320, 240)
pos = []
def main_move(event):
#When the main window moves, adjust the sub window to move with it
if pos:
sub.geometry("+{0}+{1}".format(pos[0], pos[1]))
# Change pos[0] and pos[1] to defined values (eg 50) for fixed position from main
def sub_move(event):
# Set the min values
min_w = root.winfo_rootx()
min_h = root.winfo_rooty()
# Set the max values minus the buffer for window border
max_w = root.winfo_rootx() + root.winfo_width() - 15
max_h = root.winfo_rooty() + root.winfo_height() - 35
# Conditional statements to keep sub window inside main
if event.x < min_w:
sub.geometry("+{0}+{1}".format(min_w, event.y))
elif event.y < min_h:
sub.geometry("+{0}+{1}".format(event.x, min_h))
elif event.x + event.width > max_w:
sub.geometry("+{0}+{1}".format(max_w - event.width, event.y))
elif event.y + event.height > max_h:
sub.geometry("+{0}+{1}".format(event.x, max_h - event.height))
global pos
# Set the current sub window position
pos = [event.x, event.y]
root.bind('<Configure>', main_move)
sub.bind('<Configure>', sub_move)
root.mainloop()

There's nothing built-in to facilitate this, though there are enough building blocks to build your own. You can, for example, create a frame with some custom bindings that allow you to move it around its parent using the place geometry manager.

Python:Bad Window Path Name when using deiconify

I've been having this problem with a python program I am making where if I display a TopLevel window, in this case my Help Menu, then withdraw it then try to display it again I get the following error
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python34\lib\tkinter\__init__.py", line 1533, in __call__
return self.func(*args)
File "C:\Users\****\Documents\GitHub\ProjectName\ProjectName\GUI.py", line 60, in displayHelp
self.helpMenu.display();
File "C:\Users\****\Documents\GitHub\ProjectName\ProjectName\HelpMenu.py", line 35, in display
self.deiconify();
File "C:\Python34\lib\tkinter\__init__.py", line 1646, in wm_deiconify
return self.tk.call('wm', 'deiconify', self._w)
_tkinter.TclError: bad window path name ".60000336"
The error first happened when I was withdrawing from within HelpMenu.py and using deiconify to redisplay it from the GUI.py file.
Since then I have tried multiple ways to fix the problem including calling deiconify from within HelpMenu.py and updating the copy of help menu stored in the GUI when I withdraw it.
I am running Python 3.4.2
I have already done extensive searches online and failed to find a solution to my problem. I have found other mentions of this error but they either didn't relate to my situation or their solutions did not work.
Here is the entire code for the HelpMenu.py followed by an extract from GUI.py that retains the functionality to reproduce the error but has other code removed.
#!/usr/bin/python
try:
from Tkinter import *
except ImportError:
from tkinter import *
class HelpMenu(Toplevel):
def __init__(self, parent, observer):
Toplevel.__init__(self);
self.observer = observer;#Observer is the GUI, this is here just so I can update the GUI when I withdraw this window
self.setup();
self.withdraw();
self.protocol('WM_DELETE_WINDOW', self.quit());#Changes the close button to just hide the window
def setup(self):
self.columnconfigure(0,weight=1);
w = 400;#Sets up the window position on the screen
h = 150;
sw = self.winfo_screenwidth();
sh = self.winfo_screenheight();
x=(sw-w)/2;
y =(sh-h)/2;
self.update();
self.geometry('%dx%d+%d+%d' % (w,h,x,y));
self.resizable(width=0, height=0);
self.grid();
self.title("Help Menu");
def quit(self):#Hides the window
self.withdraw();
self.observer.updateHelp(self);
def display(self):#Re-displays the window
self.deiconify();
Here is code taken from GUI.py and modified to only have the code needed to reproduce the issue.
#!/usr/bin/python
#Allows compatibility with any version of Python by checking for both versions of Tkinter
try:

self.update();#Forces and update on the window

One last note, I am slightly new to Python, so there might be other errors in my code and while I wont mind if they get pointed out, the main focus I have right now is fixing this path name error.
EDIT:Almost a month now and I have still not found a solution to the problem. Any help would be great but at this point I am probably going to have to abandon my project.

So, after a break I went back to look at this problem again.
Turns out that the issue was self.protocol('WM_DELETE_WINDOW', self.quit()) was not actually calling self.quit() and was destroying the window completely.
A quick change to self.protocol('WM_DELETE_WINDOW', self.quit) seems to have fixed it.

I think maybe the comma causes the problem. Try write it like this:
#!/usr/bin/env python
# -*- coding:utf-8 -*-
try:
from Tkinter import *

from tkinter import *
class HelpMenu(Toplevel):
def __init__(self, parent, observer):

self.observer = observer # Observer is the GUI, this is here just so I can update the GUI when I withdraw this window
self.setup()
self.withdraw()
self.protocol('WM_DELETE_WINDOW', self.quit()) # Changes the close button to just hide the window
def setup(self):
self.columnconfigure(0, weight=1)
w = 400 # Sets up the window position on the screen
h = 150
sw = self.winfo_screenwidth()
sh = self.winfo_screenheight()
x = (sw - w) / 2
y = (sh - h) / 2
self.update()
self.geometry('%dx%d+%d+%d' % (w, h, x, y))
self.resizable(width=0, height=0)
self.grid()
self.title("Help Menu")
def quit(self): # Hides the window
self.withdraw()
self.observer.updateHelp(self)
def display(self): # Re-displays the window
self.deiconify()

self.update() # Forces and update on the window
self.geometry('%dx%d+%d+%d' % (w, h, x, y)) # Sets the windows width, height and position
self.minsize(int(w), int(h / 2)) # Sets the minimum size of the window
self.configureMenu()
def updateHelp(self, helpMenu):
self.helpMenu = helpMenu
def displayHelp(self):
self.helpMenu.display()
def configureMenu(self):
# Handles configuring and setting up the menus
menu = Menu(self) # Setup the menu bar
menu.add_command(label="Help", command=self.displayHelp)
self.config(menu=menu)
def __init__(self, parent):

It works perfectly from myside.
