Python tkinter treeview double click2/29/2024 ![]() ![]() '' : Neither tree view nor headings are shown. Tree headings : (Default) Show both heading and expanding child node. Tree: Show tree view with expanding the child node. Show option headings: Show the headings without the column marked as #0 If this value is set to False then child will be in collapsed state, however it can be displayed by expanding the Tree ( + symbol ) in tree view and by double clicking in headers view. The child will have to iid of parent as option.īy default the child row can be displayed by using open=True. The identification of parent and child is done by the values for parent option and the iid. To this code we will add few more rows where some rows are child of parent row. ![]() We will extend the same code taken from our basic Treeview tutorial. Print("In OnDoubleClick and you clicked on", self.choose_action.Tkitner Treeview to add parent and child rows using insert() with parent and iid options Print("label is " + str(display_options_label))ĭisplay_options_id(row=1, column=0)ĭisplay_animal_name_value = tk.BooleanVar()ĭisplay_animal_name = tk.Checkbutton(leftsidebar, text="Animal Name", var=display_animal_name_value, width=15)ĭisplay_animal_id(row=4, column=0, sticky="W")ĭisplay_animal_number_value = tk.BooleanVar()ĭisplay_animal_number = tk.Checkbutton(leftsidebar, text="Animal Number", var=display_animal_number_value, width=15)ĭisplay_animal_id(row=5, column=0, sticky="W") Self.gohome = ttk.Button(leftsidebar, text="LambTracker\n Home", command=GoHome)ĭisplay_options_label = tk.Label(leftsidebar, text='Display Options', anchor="w") Leftsidebar = tk.Frame(animal_search_screen, borderwidth=2, relief="raised", width=40) Print("in class AnimalSearch before create frame") # Bring up the main screen again for further inputĭef _init_(self, animal_search_screen): # Add in all the other screens to hide them here when they are created Print("you clicked on the top home button") import tkinter as tkĪnimal_search_screen.geometry("1024x768+0+0")Īnimal_search_screen.title("Animal Search") ![]() The key appears that you have to be in a class to bind the double click.I expanded it to actually bring up another window (screen) so it's obvious that it's actually working. Self.choose_action.bind("", self.OnDoubleClick) Self.choose_action.insert('animals', 'end', 'animalreports', text='Animal Reports') Self.choose_action.insert('animals', 'end', 'animaladd', text='Add/Edit Animal') Self.choose_action.insert('animals', 'end', 'animalsearch', text='Animal Search') Self.choose_action.insert('', 0, 'animals', text='Animals') Self.choose_action.title = 'LambTracker Home' This code works but using pack won't work for the larger application. And in any case I will need to move to grid eventually so I've got to get it working that way. I can add the left to the pack and get it on the left but then it's centered vertically. This is the code in the class form but the frame is in the center. Ideally it would be in a separate class as shown below but I can't seem to get that to work with grid placement.

Eventually there will be a structure here so that # This is just dummy code to get the double click working. Leftsidebar = tk.Frame(root, borderwidth=2, relief="raised", width=45) # Create the choose action sidebar that will go to specific screens As a test I put my tree in the main root window and then it fails with an error on the bind of "AttributeError: 'Treeview' object has no attribute 'OnDoubleClick'" import tkinter as tk I'm trying to create a treeview to use as a selection sidebar. ![]()
