module widgets.xtableview

Extension of the TableView widget which can as well insert lists into the ttk.Treeview widget.

The widget TableView provides an extension for the TableView table widget with a readData function, getting header and lists inheriting all methods and options from TableView.

Hint: This functionality should be better implemented as a Mixin.

Below you see the inheritance hierarchy and the added methods:

@startuml
class "ttk.TreeView" as Treeview {
     configure(kwargs)
     cget("property")
     etc()
}
class "dbpp.widgets.TableView" as TableView {
     readTabfile(filename)
     pack(kwargs)
     pack_forget()
}
class "dbpp.widgets.XTableView" as XTableView {
     insert_data(colnames,data)
}
Treeview <- TableView
TableView <- XTableView
@enduml

Examples:

import tkinter as tk
import tkinter.ttk as ttk
from dbpp.widgets.XTableView import XTableView 
root = tk.Tk()
root.title('XTableView Demo')
dgtab=XTableView(root)
dgtab.getFrame().pack(side='top',fill='both',expand=True)
dgtab.insert_data(['Col1','Col2'],
     data=[['val1.1','val1.2'], ['val2.1','val2.2']])
root.geometry("400x300")
root.mainloop()
