Is it possible to select multiple rows in a treeview widget?

Is it possible to select multiple rows in a treeview widget?, further, how do you then get the input/selected rows.

Here is a treeview I have created, however it is not possible for me to select both rows.

treeview

If this is not possible, is their a widget in tkinter or ttk which allows for this?

Solution

  • Yes, it is possible to get a tuple of the selected items using selection() method. Once you get the tuple, you can access each item using the item() method. Here is an example.

    P.S. In the code, select multiple items by pressing Ctrl and clicking on rows and then hit Enter.

    import tkinter as tk
import tkinter.ttk

def select():
    curItems = tree.selection()
    tk.Label(root, text="\n".join([str(tree.item(i)['values']) for i in curItems])).pack()

root = tk.Tk()
tree = tkinter.ttk.Treeview(root, height=4)

tree['show'] = 'headings'
tree['columns'] = ('Badge Name', 'Requirement', 'Cost', 'Difficulty')
tree.heading("#1", text='Badge Name', anchor='w')
tree.column("#1", stretch="no")
tree.heading("#2", text='Requirement', anchor='w')
tree.column("#2", stretch="no")
tree.heading("#3", text='Cost', anchor='w')
tree.column("#3", stretch="no")
tree.heading("#4", text='Difficulty', anchor='w')
tree.column("#4", stretch="no")
tree.pack()

tree.insert("", "end", values=["IT Badge", "Track Computer", "$1.50", "2"])
tree.insert("", "end", values=["Selfless Badge", "Track Yourself", "$100.50", "10"])
tree.insert("", "end", values=["Tracking Badge", "Track Animal", "$4.50", "7"])

tree.bind("<Return>", lambda e: select())

root.mainloop()
