I have some entries in tkinter. currently, I need to move the cursor to each entry and click it to select it. I am looking to do this using the arrow keys. I saw we can use bind_class to select all the Entry widgets, however, I don't know how to work around focus() to move Up/Down/Left/Right in entries.
import tkinter as tk
class Data:
def __init__(self):
self.x = tk.IntVar()
class SampleApp(tk.Tk):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.minsize(700, 700)
container = tk.Frame(self)
container.pack()
self.data = Data()
self.frames = {}
for F in (PageOne, ):
frame = F(container, self.data)
self.frames[F] = frame
frame.grid(row=0, column=0, sticky="nsew")
def show_frame(self, c):
frame = self.frames[c]
frame.tkraise()
class PageOne(tk.Frame):
def __init__(self, parent, data):
super().__init__(parent)
self.data = data
self.row_list = []
for i in range(4):
self.entry_list = []
for j in range(4):
self.A = tk.Entry(self)
self.A.grid(row=i, column=j)
self.entry_list.append(self.A)
self.row_list.append(self.entry_list)
self.bind_class("Entry", "<Down>", self.next_widget)
self.bind_class("Entry", "<Up>", self.next_widget)
self.bind_class("Entry", "<Right>", self.next_widget)
self.bind_class("Entry", "<Left>", self.next_widget)
def next_widget(self, event):
event.widget.focus()
return ("break")
app = SampleApp()
app.mainloop()
