when use arrow key move to left , cursor jumping to the first column)

[Vichai1877]

This program from your example ,

I found when use arrow key to move left cursor , cursor alway jumping to first column

from tksheet import Sheet
import tkinter as tk

class demo(tk.Tk):
def init(self):
tk.Tk.init(self)
self.grid_columnconfigure(0, weight=1)
self.grid_rowconfigure(0, weight=1)
self.frame = tk.Frame(self)
self.frame.grid_columnconfigure(0, weight=1)
self.frame.grid_rowconfigure(0, weight=1)
self.sheet = Sheet(self.frame,
data=[[f"Row {r}, Column {c}\nnewline1\nnewline2" for c in range(50)] for r in range(500)])
self.sheet.enable_bindings(
"single_select",
"drag_select",
"edit_cell",
"paste",
"cut",
"copy",
"delete",
"select_all",
"column_select",
"row_select",
"column_width_resize",
"double_click_column_resize",
"arrowkeys",
"row_height_resize",
"double_click_row_resize",
"right_click_popup_menu",
"rc_select",
)
self.sheet.extra_bindings("begin_edit_cell", self.begin_edit_cell)
self.sheet.edit_validation(self.validate_edits)
self.sheet.popup_menu_add_command("Say Hello", self.new_right_click_button)
self.frame.grid(row=0, column=0, sticky="nswe")
self.sheet.grid(row=0, column=0, sticky="nswe")

def new_right_click_button(self, event=None):
    print ("Hello World!")

def begin_edit_cell(self, event=None):
    return event.value

def validate_edits(self, event):
    # remove spaces from any cell edits, including paste
    if isinstance(event.value, str) and event.value:
        return event.value.replace(" ", "")

app = demo()
app.mainloop()

Hello, thanks for your report

I'm sorry to say I cannot re-create this behavior, could you provide more detail please. These are the things I've tried just now with your above code:

• I have tried using left arrow key inside the cell text editor, it moves one character left as intended.
• I have tried using left arrow key the move the cell selection one left, it moves one cell left as intended.

Kind regards

I get the same behaviour as described by Vichai1877.
When I use the arrows to navigate; right, up, down all perform as expected.
Left arrow jumps to the furthest left column in one jump.
As I am using this in a non-admin Win10 environment I had to install tksheet into user site-packages directory.
This behaviour occurs in the included demo

from tksheet import Sheet
import tkinter as tk


class demo(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self.grid_columnconfigure(0, weight = 1)
        self.grid_rowconfigure(0, weight = 1)
        self.frame = tk.Frame(self)
        self.frame.grid_columnconfigure(0, weight = 1)
        self.frame.grid_rowconfigure(0, weight = 1)
        self.sheet = Sheet(self.frame,
                           data = [[f"Row {r}, Column {c}\nnewline1\nnewline2" for c in range(50)] for r in range(500)])
        self.sheet.enable_bindings()
        self.frame.grid(row = 0, column = 0, sticky = "nswe")
        self.sheet.grid(row = 0, column = 0, sticky = "nswe")


app = demo()
app.mainloop()

Apologies, I discovered it was scrolling to put the selected column on the right hand side of the view when selecting a column that was not totally visible.

The code for the arrow key functions is also very poor, fixes and refactoring incoming soon.

Kind regards and thank you for raising the issue

Hello,

The issue should be resolved now in 7.4.5 but let me know if you have further issues

[MonkeyCandies]

Thanks for the swift reply, sadly the issue still persists for me on 7.4.6. Python version is Python 3.12.9
I am on a non-admin win10 account here so will try the same at home where I can control the python version and install location.
Will update if the issue occurs there too.

[MonkeyCandies]

Confirmed in my own environment with win10 and admin. Python 3.13.2 & tksheet 7.4.6, that the demo script above (and other scripts) still have the 'left arrow jumps to first column' issue.
Thank you :)

Hello, thanks for the testing and report,

I have tried to fix it in 7.4.7, I'm wondering if it's related to the recent binding of Home as pressing the Home key for me has the same behavior.

I've added a "break" to the arrow key left function to try to prevent additional functions from running afterwards in case Home was being triggered and I've unbound Command Left for non-MacOS devices.

[Vichai1877]

Thanks for the hard work you did so quickly. In the latest version 7.4.7 the arrow keys are working properly.
