I have a code that makes multiple canvases on Python tkinter (9 canvas). With this function (I destroy all item on window with destroy function at start):
def show_board(self):
self.destroy_start()
canvas_list = []
for i in range(9):
dist = {
f"canvas{i + 1}": Canvas(height=150, width=150, bg=BOARD_COLOR),
}
canvas_list.append(dist)
for n in range(len(canvas_list)):
canvas_dict = canvas_list[n]
for (key, val) in canvas_dict.items():
if n == 0 or n <= 2:
row = 0
if n == 0:
col = 0
val.grid(row=row, column=col, padx=(125, 0))
elif n == 1:
col = 1
val.grid(row=row, column=col)
elif n == 2:
col = 2
val.grid(row=row, column=col)
elif 2 < n <= 5:
row = 1
if n == 3:
col = 0
val.grid(row=row, column=col, padx=(125, 0))
elif n == 4:
col = 1
val.grid(row=row, column=col)
elif n == 5:
col = 2
val.grid(row=row, column=col)
elif n > 5:
row = 2
if n == 6:
col = 0
val.grid(row=row, column=col, padx=(125, 0))
elif n == 7:
col = 1
val.grid(row=row, column=col)
elif n == 8:
col = 2
val.grid(row=row, column=col)
# loop in canvas and get x and y of the click and set the image when user click
for item in canvas_list:
for (key, val) in item.items():
canvas_x, canvas_y = val.winfo_rootx(), val.winfo_rooty()
print(canvas_x, canvas_y)
self.check_click(can=val)
self.pl1_score_label.grid(column=0, row=3, padx=(100, 0))
self.pl2_score_label.grid(column=2, row=3)
and I want to when user clicks on window on one of these canvases for the canvas to create an image (just than canvas)
I try to do this with last loop in upper function
def display_mouse_pos(self, event):
self.window.update()
x = event.x
y = event.y
print(x, y)
def check_click(self, can):
self.window.bind("<Button-1>", self.display_mouse_pos)
can.create_image(100, 100, image=self.x_image)
self.window.update()`
but I get that image on all canvas I know problem is my function and for loop I can't find the way to check if screen get clicked or not and if its get clicked which canvas get clicked and who can I make a picture in that canvas
I want to change the colour of a button based on its row and column. I am able to search for adjacent buttons, but cant do anything with them. The code is a python version of the board game Othello, and I am trying to get the "sandwiching" aspect of the game to run. Ideally, it stays in the grid system so I am able to code to my ability
from tkinter import *
### Function to change button colour ###
def changeColour(tempButton, row, column):
if tempButton.cget("bg") == "black":
tempButton.configure (bg = "white")
else:
tempButton.configure (bg = "black")
sandwichButton(tempButton, row, column)
### Function to sandwich adjacent buttons ###
def sandwichButton(originButton, row, column):
for x in range (-1,2,1):
for y in range (-1,2,1):
aRow = (row + y)
aColumn = (column + x)
adjacentInfo = find_position(othello, aRow, aColumn)
endButtonInfo = find_position(othello, aRow + y, aColumn + x)
if adjacentInfo["row"] == (aRow) and adjacentInfo["column"] == (aColumn):
adjacentButton = ADJACENT INFORMATION
if endButtonInfo["row"] == (aRow + y) and endButtonInfo["column"] == (aColumn+x):
if originButton.cget("bg") == "black":
adjacentButton.configure (bg = "white")
else:
adjacentButton.configure (bg = "black")
### Function to find button position ###
def find_position(frame, row, column):
for children in frame.children.values():
info = children.grid_info()
if info["row"] == row and info["column"] == column:
return info
break
### Creating the window ###
othello = Tk()
othello.title("Othello Draft 1")
othello.geometry("800x800")
### Creating buttons ###
for r in range (8): #Rows
for c in range(8): #Columns
button = Button(othello, width = 10, height = 5)
button.grid(row = r, column = c)
button.configure (bg = "green", command = lambda buttonName = button, r = r, c = c: changeColour(buttonName, r, c))
### Running the window ###
othello.mainloop()
You could add the buttons to a list and use an if and elif statement to configure the buttons and input your conditions into the if.
for button in [list your buttons here]
if condition:
button.config(command=command(), bg=colour)
elif condition:
button.config(command=command2(), bg=colour2)
I'm making Minesweeper with tkinter. I want to have it so that when a button with 0 mines surrounding it is clicked, all the buttons around that one are automatically clicked.

The issue is that in the recursion process, the code is backtracking on previous squares. When checking a new square, be sure it has not already be checked.
In the num function, add a line of code to skip squares that have already been disabled:
def num(x, y):
if buttonlist[x]["state"] == "disabled": return # add this line
a = rowlist[x]
b = columnlist[x]

the problem i have is that lets say if i press the down arrow until my selected coordinate is [0,9], the code should colour the 6th to 10th box from top down, in the first column, but it colours the 5th to 9th box.
i have tried debugging it by checking if the coordinates x and y used in the last function refresh_ocean were wrong, but they were as expected
So the short and simple fix is to change (y-1) to (y+1).
That said I made a few changes:
Rewrote some of your names to follow PEP8 style guide.
Converted your refresh_ocean method to handle the initial draw and all draws afterwords. As well as added a delete('all') to clear the board so we are not draw on top of the previous objects. This will prevent using up more memory as the game progresses.
Cleaned up imports and changed from tkinter import * to import tkinter as tk. This will help prevent overwriting other things in the namespace.
By writing your refresh_ocean to handle all the drawing we can specify what needs to be drawn with tags like 'player1' and 'ai'.
Changed += to .append() for your list generation as append() is twice as fast as '+=. See this post: Difference between “.append()” and “+= []”?
Changed you single label of headers into a loop to create each label evenly. This will allow for a more accurate header then trying to manually set spaces in a single string.
Lastly because you are already checking of the key is one of the 4 arrow keys we can use a single bind to '<Key>' and get the same results as all 4 binds.

i changed your iteration from range(row-size, row) to range(row, row+size) and added bounds checking, but that should probably be moved to the movement handling.

ps: your drawing new squares on top of the old squares. you might want to clear the ocean before drawing.
I have 2 classes, i create the instance of each class like this

root.geometry("%dx%d+0+0" % (w, h))

UI_Class = GUI(root)
Program_Class = Program()
root.mainloop()
i set variables in GUI like this:
self.tenAmShowBtn = Button(self.fMain,text='10am Show',command=Program_Class.tenAmShow)
self.tenAmShowBtn.grid(column=0,row=2)
and to access variables in (ex)GUI from Program i do like this:
UI_Class.tenAmShowBtn.config(bg='#00f0ff')
but i keep getting errors like NameError: name 'UI_Class' is not defined
and NameError: name 'Program_Class' is not defined
and AttributeError: 'GUI' object has no attribute 'tenAmShowBtn'i don't understand how the hell do i do this, the Program class continuosly has to access the GUI and edit variables and widgets, but i can't access variables, keep getting error after error, it woks great when i put everything in 1 class, i just CAN'T get this to work with 2 separete classes.
I put the whole code because i cannot explain in just bits of code, i aplogise.
