Need for hereditary feature that was in classic tkinter. The Treeview

[emircetinmemis]

Hi, I have been searching about UI frameworks for tkinter, and found out the most accurate one was customtkinter for me. I was about to turn my application to customtkinter, but I realized that I'm facing with a problem on a specific widget. My application uses several tables or lists on displaying purposes. So with this, I must be able to use a widget like Treeview which comes from the culture of tkinker.

• The mentioned widget call

  ttk.Treeview

An example of a basic execution;

from    tkinter         import ttk
import  customtkinter   as ctk
import  tkinter         as tk

class WithNormalTk(tk.Tk) :

  def __init__(self, *args, **kwargs) :
    super().__init__(*args, **kwargs)

    treeview = ttk.Treeview(self, height=4, show="headings", selectmode="browse")
    treeview.pack(side="top", fill="both", expand=True)

    treeview["columns"] = ("one", "two", "three")

    treeview.heading("one", text="Column A")
    treeview.heading("two", text="Column B")
    treeview.heading("three", text="Column C")

    treeview.column("one", width=100)
    treeview.column("two", width=100)
    treeview.column("three", width=100)

    treeview.insert("", "end", values=("1", "2", "3"))
    treeview.insert("", "end", values=("4", "5", "6"))
    treeview.insert("", "end", values=("7", "8", "9"))

class WithCustomTk(ctk.CTk) :

  def __init__(self, *args, **kwargs) :
    super().__init__(*args, **kwargs)

    # TODO: Find a way out.

if __name__ == "__main__" :

  app = WithNormalTk()
  app.mainloop()

  app = WithCustomTk()
  app.mainloop()

And this shortly results as;

What I have tried to do;

• I have tried to use the scrollable frame that you have done. It kinda worked, but not it was seem to be understandable that, that widget was not supposed to look like that or stay like that. And also the second case with the scrollable frame problem was the core functionalies served by treeview, with a couple of binding I was almost able to reach whatever I want inside that table, but it is not the case with scrollable frame.

The solution;

• Treeview like widget should be added.

I forgat too add this.

For the "What I have tried to do;" part,

• I also tried to mix things up by using CTk widgets with ttk.Treeview by setting up this ctk.deactivate_automatic_dpi_awareness() And again as I said before, It doesn't just look like what ,it actually should look like.

You can still use a tkinter treevieew in CustomTkinter:

from tkinter import ttk
import customtkinter

class WithCustomTk(customtkinter.CTk):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

        self.grid_columnconfigure(0, weight=1)

        self.font = customtkinter.CTkFont("Arial", 18)

        self.treeview_heading_style = ttk.Style(self)
        self.treeview_heading_style.theme_use("clam")
        self.treeview_heading_style.configure("Treeview.Heading", background="black", foreground="white",
                                              highlightthickness=0, bd=0, font=self.font)

        self.treeview_style = ttk.Style(self)
        self.treeview_style.theme_use("clam")
        self.treeview_style.configure("Treeview", background="black", foreground="white",
                                      highlightthickness=0, bd=0, font=self.font)

        self.treeview = ttk.Treeview(self, height=4, show="headings", selectmode="browse")
        self.treeview.grid(row=0, column=0, sticky="nsew")

        self.treeview["columns"] = ("one", "two", "three")

        self.treeview.heading("one", text="Column A")
        self.treeview.heading("two", text="Column B")
        self.treeview.heading("three", text="Column C")

        self.treeview.column("one", width=100)
        self.treeview.column("two", width=100)
        self.treeview.column("three", width=100)

        self.treeview.insert("", "end", values=("1", "2", "3"))
        self.treeview.insert("", "end", values=("4", "5", "6"))
        self.treeview.insert("", "end", values=("7", "8", "9"))

if __name__ == "__main__":
    app = WithCustomTk()
    app.mainloop()
