The following program illustrates how to add items to the Treeview: import tkinter as tk To add an item at the beginning of the list, you use zero ( 0) instead of tk.END constant: tree.insert( '', 0, values=contact) Code language: Python ( python ) The following example adds an item at the end of the item list: tree.insert( '', tk.END, values=contact) Code language: Python ( python ) To add an item (or a row) to a Treeview widget, you use the insert() method of the Treeview widget object. Showinfo(title= 'Information', message= ','.join(record))Ĭode language: Python ( python ) Adding an item to the Treeview widget Tree.heading( 'last_name', text= 'Last Name')Ĭontacts.append(( f'first ', f'email add data to the treeview for contact in contacts:ĭef item_selected (self, event): for selected_item in (): Tree.heading( 'first_name', text= 'First Name') Tree = ttk.Treeview(root, columns=columns, show= 'headings') The following program shows how to use the Treeview widget to display tabular data: import tkinter as tkĬolumns = ( 'first_name', 'last_name', 'email') Using Tkinter Treeview to display tabular data The first row of the Treeview consists of headings that identify each column by a name. The remaining columns contain values of each row. The first column may contain text and an icon that indicates whether it can be expansible or not. To create a Treeview widget, you use the ttk.Treeview class: tree = ttk.Treeview(container, **options) Code language: Python ( python )Ī Treeview widget holds a list of items. Introduction to the Tkinter Treeview widgetĪ Treeview widget allows you to display data in both tabular and hierarchical structures.

Text_wid.insert(tk.Summary: in this tutorial, you’ll learn about the Tkinter Treeview widget and how to use it to display both tabular and hierarchical data. Text_wid.grid(row=0, column=0, sticky='nsew') Text_wid = tk.Text(ame_right, width=30, height=20) ame_right=tk.Frame(self.root, bg='salmon', Tk.Label(ame_left, text='Label %d' % (ctr+1), ame_left=tk.Frame(self.root, bg='lightblue', Tk.Button(self.root, bg='blue', text='Quit',

Post some code if you want additional help. When this program was almost finished, it occurred to me that one of tkinter's gotchas is that width is sometimes measured in pixels and sometimes in letters. This is an example of doing something in the ball park of what you are asking.

I don't know how to keep the treeview constrained within the pane, i've tried putting it in a frame as well as adjusting the and columnconfigure but still the same thing occurs, i dont necessarily have to use a panedwindow but i just want it to be constrained to a specific portion of the screen and not the whole top halfĭisplaying data on the right half of my window with another free portion on the left side that would have buttons and entry boxes I also tried doing it with just one panedwindow like this but it also had no effect: panel_left=tk.PanedWindow(bd=2,bg='yellow',orient=tk.HORIZONTAL) data_tree = ttk.Treeview(self.root, columns=json_tree_columns, show='headings', ) panel_left.add(data_tree) panel_left.pack(fill=tk.BOTH,expand=True)` but it still makes the treeview take up the entire screen

Then this happens when I attempt to add the treeview to the panel_right using the following code: data_tree = ttk.Treeview(panel_right,columns=json_tree_columns, show='headings', ) Panel_right.pack(side='right', fill=tk.BOTH, expand=1) Panel_right = tk.PanedWindow(bd=2, bg='orange') Panel_left.pack(side='left',fill=tk.BOTH,expand=1) Panel_left=tk.PanedWindow(bd=2,bg='yellow') The best explanation I can show is by using the PanedWindow where I made two panes on the left and right side of the screen using the following code: class MyGUI: I have tried adding frames directly to the root but as soon as I add the treeview any of the frames, it immediately resizes and takes up the entire top portion of the screen regardless of what I do. I am trying to have a treeview displaying data on the right half of my window with another free portion on the left side that would have buttons and entry boxes.
