6/4/2023 0 Comments Treeview tkinterUsing this after adding header and columns ( check the code below ) one record is added with iid=1 ( unique id of the row )īelow this Treeview we will provide inputs using Label, Text, OptionMenu and Radio buttons to take one input row data and add to the row on Click of a Button.ī1 = tk.Button(my_w, text='Add Record', width=10, Text : Text to appear at right of icon column. Iid : Optional, Identifier of the item ( row ), Treeview will create unique iid if not given. To added at the bottom 'end' and 0 if at top. Trv.grid(row=1,column=1,columnspan=4,padx=20,pady=20) adding one record insert(parent, index, iid=None, **kw) parent : For Parent row it should be '', for child row parent iid to be used. Trv=ttk.Treeview(my_w,selectmode='browse') Here we have declared one Treeview and use the object trv for further management of the Treeview. Below the Treeview, input boxes and options are available to add nodes to this Treeview using insert() method. Here we have one student record table ( no database here ) and one record is already available. We can use insert() to add one parent of main node ( row ) to the Treeview. Text_wid.insert(tk.Adding rows using insert() in Tkinter Treeview 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.
