Get OptionMenu value after selection and store in array - python-3.x

Question

Here is the code:
from tkinter import *
class Window(Canvas):
def __init__(self,master=None,**kwargs):
Canvas.__init__(self,master,**kwargs)
self.frame = Frame(self)
self.create_window(0,0,anchor=N+W,window=self.frame)
self.row = 1
self.input_n_or_s = []
self._init_entries()
def _init_entries(self):
n_or_s = Label(self.frame, text='N or S', font='Helvetica 10 bold').grid(row = self.row, column = 1)
self.row += 1
def add_entry(self):
n_or_s = ['N', 'S']
variable = StringVar(self.frame)
variable.set(n_or_s[0])
option_n_or_s = OptionMenu(self.frame, variable, *n_or_s)
option_n_or_s.grid(row = self.row, column = 1)
self.row += 1
#def save_entry(self):
if __name__ == "__main__":
root = Tk()
root.resizable(0,0)
root.title('Lot')
lot = Window(root)
lot.grid(row=0,column=0)
scroll = Scrollbar(root)
scroll.grid(row=0,column=1,sticky=N+S)
lot.config(yscrollcommand = scroll.set)
scroll.config(command=lot.yview)
lot.configure(scrollregion = lot.bbox("all"), width=1000, height=500)
def add_points():
lot.add_entry()
lot.configure(scrollregion = lot.bbox("all"))
b1 = Button(root, text = "Add points", command = add_points)
b1.grid(row=1,column=0)
def get_value():
b1.destroy()
lot.save_entry()
b2 = Button(root, text = "Get value!", command = get_value)
b2.grid(row=2,column=0)
root.mainloop()
Can someone help me on what to put inside the 'save_entry()' function to get each values of the OptionMenus (assuming that the 'add entry' button has been clicked more than 5 times), and then put each values in the 'input_n_or_s' array for later use?
For example:
Here's the GUI wherein the user clicked the 'Add points' button 10 times, and then changed some default values to 'S':
My expected output should look like this:
['S', 'N', 'N', 'S', 'N', 'N', 'N', 'S', 'N', 'S']

Here you go I think this is what you want.
from tkinter import *
class Window(Canvas):
def __init__(self,master=None,**kwargs):
Canvas.__init__(self,master,**kwargs)
self.frame = Frame(self)
self.create_window(0,0,anchor=N+W,window=self.frame)
self.row = 1
self.input_n_or_s = []
self._init_entries()
def _init_entries(self):
n_or_s = Label(self.frame, text='N or S', font='Helvetica 10 bold').grid(row = self.row, column = 1)
self.row += 1
def add_entry(self):
n_or_s = ['N', 'S']
self.variable = StringVar(self.frame)
self.variable.set(n_or_s[0])
self.menu = option_n_or_s = OptionMenu(self.frame, self.variable, *n_or_s)
option_n_or_s.grid(row = self.row, column=1)
self.row += 1
def save_entry(self):
print(self.variable.get())
if __name__ == "__main__":
root = Tk()
root.resizable(0, 0)
root.title('Lot')
lot = Window(root)
lot.grid(row=0,column=0)
scroll = Scrollbar(root)
scroll.grid(row=0,column=1,sticky=N+S)
lot.config(yscrollcommand = scroll.set)
scroll.config(command=lot.yview)
lot.configure(scrollregion = lot.bbox("all"), width=1000, height=500)
root.cnt = 0
def add_points():
root.cnt += 1
if root.cnt < 5:
return
root.cnt = 0
lot.add_entry()
lot.configure(scrollregion = lot.bbox("all"))
lot.input_n_or_s.append(lot.variable.get())
b1 = Button(root, text = "Add points", command = add_points)
b1.grid(row=1,column=0)
def get_value():
b1.destroy()
lot.save_entry()
b2 = Button(root, text = "Get value!", command = get_value)
b2.grid(row=2, column=0)
root.mainloop()

Answer 2

I finally figured it out. The reason that I can't manage to make it work before is that I'm trying to get the output from the OptionMenu instead of the variable.
def add_entry(self):
....
self.input_n_or_s.append(variable)
def save_entry(self):
for entry in self.input_n_or_s:
x = str(entry.get())
self.north_or_south.append(x)
print(self.north_or_south)
So here's the whole working code:
from tkinter import *
class Window(Canvas):
def __init__(self,master=None,**kwargs):
Canvas.__init__(self,master,**kwargs)
self.frame = Frame(self)
self.create_window(0,0,anchor=N+W,window=self.frame)
self.row = 1
self.input_n_or_s = []
self.north_or_south = []
self._init_entries()
def _init_entries(self):
n_or_s = Label(self.frame, text='N or S', font='Helvetica 10 bold').grid(row = self.row, column = 1)
self.row += 1
def add_entry(self):
n_or_s = ['N', 'S']
variable = StringVar(self.frame)
variable.set(n_or_s[0])
option_n_or_s = OptionMenu(self.frame, variable, *n_or_s)
option_n_or_s.grid(row = self.row, column = 1)
self.row += 1
self.input_n_or_s.append(variable)
def save_entry(self):
for entry in self.input_n_or_s:
x = str(entry.get())
self.north_or_south.append(x)
print(self.north_or_south)
if __name__ == "__main__":
root = Tk()
root.resizable(0,0)
root.title('Lot')
lot = Window(root)
lot.grid(row=0,column=0)
scroll = Scrollbar(root)
scroll.grid(row=0,column=1,sticky=N+S)
lot.config(yscrollcommand = scroll.set)
scroll.config(command=lot.yview)
lot.configure(scrollregion = lot.bbox("all"), width=1000, height=500)
def add_points():
lot.add_entry()
lot.configure(scrollregion = lot.bbox("all"))
b1 = Button(root, text = "Add points", command = add_points)
b1.grid(row=1,column=0)
def get_value():
b1.destroy()
lot.save_entry()
b2 = Button(root, text = "Get value!", command = get_value)
b2.grid(row=2,column=0)
root.mainloop()
Still, thanks for the effort on helping me, Daniel Huckson. And Bryan Oakley, thanks for your concern also.
