The coordinates of the Entry widget (canvas) when moving

[wuf]

Hi berckut72
Here something to experiment with. Try to forget globals:

import tkinter as tk
 
root = tk.Tk()
root.geometry('600x800+10+10')
root.resizable(width=False, height=False)

def build_canvas_setup(canvas):
    xorg_txt = 30
    yorg_txt = 10
    xorg_entry = 100
    yorg_entry = 40
    ystep = 50
    
    entry_vars = list()
    
    for index in range(8):
        # Place text canvas object
        tx_slice = 'txt{}'.format(index+1)
        txtn = tx_slice*7
        canvas.create_text(xorg_txt, yorg_txt+ystep*index, text=txtn,
            anchor=tk.NW, tags='all')
            
        # Place entry widget as canvas object
        entry_var = tk.StringVar()
        entry = tk.Entry(canvas, bd = 0, justify = tk.CENTER, bg = '#7F7F7F',
            fg='white', textvariable=entry_var, width = 6)
        canvas.create_window(
            xorg_entry, yorg_entry+ystep*index, window=entry, tags='all')
        entry_vars.append(entry_var)
    
    return entry_vars    
 
def button4_event(event):
    # Linux wheel event
    print('Button-4')
    move_canvas_objects('up')
    
def button5_event(event):
    # Linux wheel event
    print('Button-5')
    move_canvas_objects('down')

def mouse_wheel_events(event):
    # Window wheel events
    if event.delta == -120:
        direction = 'down'
    elif event.delta == 120:
        direction = 'up'
    else:
        return
    move_canvas_objects(direction)
        
def move_canvas_objects(direction):
    if direction == 'up':
        canvas1.move('all', 0, -1)
    elif direction == 'down':
        canvas1.move('all', 0, 1)
    
canvas1 = tk.Canvas(root, width=600, height=750, highlightthickness=0)
canvas1.pack()
 
entry_vars = build_canvas_setup(canvas1)

for index, entry_var in enumerate(entry_vars):
    entry_value = 100 + index
    entry_var.set(entry_value)
    
# For Linux only    
canvas1.bind('<Button-4>', button4_event)
canvas1.bind('<Button-5>', button5_event)
# For Windows only
canvas1.bind('<MouseWheel>', mouse_wheel_events)

root.mainloop()
