Insert tkinter Treeview widget

Question

This is my sample code. I want the elements entered in the record to be inserted into the tree image when I press the enter button. I am new to python and tkinter, and there are not many problems with treeview.

class PurchaseEntry(tk.Frame): def __init__(self, parent, controller): tk.Frame.__init__(self, parent) self.controller = controller PurchaseEntry.configure(self, bg='white') label = ttk.Label(self, text='Purchase Entry', font=LARGE_FONT2) label.grid(row=0, columnspan=3, sticky='w') purchase_entry = ttk.Label(self, text='Purchase Entry:') purchase_entry.grid(row=1, column=0) self.entry_val = tk.StringVar() self.entry_1 = ttk.Entry(self, width=100, textvariable=self.entry_val) self.entry_1.grid(row=1, column=2, columnspan=2, sticky='w') self.entry_1.focus() self.entry_btn = ttk.Button(self,text='Enter', command=self.insert_value) self.entry_btn.grid(row=1, column=4, columnspan=2, sticky='w') self.chat1 = ttk.Treeview(self) chat1 = ttk.Treeview( self, height=28, columns=('dose', 'date modified'), selectmode="extended") chat1.heading('#0', text='item', anchor=tk.CENTER) chat1.heading('#1', text='dose', anchor=tk.CENTER) chat1.heading('#2', text='date modified', anchor=tk.CENTER) chat1.column('#1', stretch=tk.YES, minwidth=50, width=100) chat1.column('#2', stretch=tk.YES, minwidth=50, width=120) chat1.column('#0', stretch=tk.YES, minwidth=50, width=400) chat1.grid(row=2, column=2, columnspan=4, sticky='nsew') def insert_value(self): value = self.entry_val.get() # Inserts data written in the entry box to the treeview widget when Enter button is pressed. # Clears the Entry box, ready for another data entry. self.entry_1.delete(0, 'end') self.chat1.insert('WHAT SHOULD I GIVE AS AN ARGUMENT?') 

What should I pass as an argument? Or is there a tree for the right widget for this, or can someone suggest a widget suitable for this problem? thanks

You seem to be only interested in how to insert the data that the user enters into Tkinter.Entry() into ttk.Treeview() after Tkinter.Button() .

I designed a simple interface to show you how to solve this problem. You can adapt my solution to your problem.

Here's what the app looks like:

So I set the self.i counter to naming elements. But instead, you can add a label and an entry for this purpose and insert element names in the same way as other Tkinter.Entry() .

Here is the insertion method:

 def insert_data(self): """ Insertion method. """ self.treeview.insert('', 'end', text="Item_"+str(self.i), values=(self.dose_entry.get() + " mg", self.modified_entry.get())) # Increment counter self.i = self.i + 1 

self.dose_entry.get() main trick here is to get the data that the user enters using the get() method, which is represented by the actions self.dose_entry.get() and self.dose_modified.get() .

This is done, now you need to attach this method to a button that must be pressed to start the insert operation by using the option command :

 self.submit_button = Tkinter.Button(self.parent, text="Insert", command=self.insert_data)

Remarks:

I wrote this in Python 2.7, but it should work if you are using Python 3.x.
