You seem to be interested only in how to insert data the user types within Tkinter.Entry()
widgets into ttk.Treeview()
after a Tkinter.Button()
click.
I designed a simple interface to show you how to resolve this. You can adapt my solution to your problem.
Here is how the application demo looks like:
So I set a counter self.i
to name the items. But you can add a label and an entry for this purpose instead and you insert items names similarly to the the other Tkinter.Entry()
entries.
The insertion method is this one:
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
May be the main trick here is to retrieve the data the user types using get()
method which thing is represented by self.dose_entry.get()
and self.dose_modified.get()
actions.
This is done, you need now to bind this method to the button to be pressed to trigger the insertion action using the command
option:
self.submit_button = Tkinter.Button(self.parent, text="Insert",
command=self.insert_data)

Note:
I coded this in Python 2.7, but it should work if you're using Python 3.x.
