Width is the width that defines each column. Step 2: Set column properties tv.column(ac,width=70,anchor='e') Step 1: Create Treeview tv=ttk.Treeview(root,columns=ac,show='headings',height=7)Ĭolumns set the name of the column, show='headings' means the first row is a table header, height=7 means the height of 7 rows is displayed Tv=ttk.Treeview(root,columns=ac,show='headings',height=7) The products are divided into 4 parts of electronic products, cosmetics, clothing and daily necessities.

When there are many files or directories, the scrolling display ybar=tk.Scrollbar(f,orient=tk.VERTICAL, show='tree', indicating a tree structure. Id=tv.insert(parent,'end',text=d,open=False) Node=tv.insert('','end',text=path,open=True)
