🔒 Tkinter TTK Treeview - toggle selection when clicking item

[quick coyote]

when the user clicks an item in the Treeview widget, the goal is to select the item if it's not already selected or de-select it if it selected.. sounds simple, right?

    def toggle_selection(self, event):
        """Toggle selection between the clicked item and no selection."""
        self.click += 1
        print('-' * 20, self.click, '-' * 20)
        
        # Identify the row that was clicked
        item = self.tree.identify_row(event.y)
        print(f'Item: {item}')
        if item:
            current_selection = self.tree.selection()
            print(f'Current selection: {current_selection}')
            # If the clicked item is already selected, clear the selection
            if item in current_selection:
                print('yes, item is in current selection')
                for i in self.tree.selection():
                    print(f'Item: {i}')
                    self.tree.selection_remove(i)
            else:
                # Otherwise, select only the clicked item
                print('no, item is not in the current selection')
                self.tree.selection_set(item)
                
            # Update toolbar button states after changing selection
            self.update_toolbar_button_states()
        else:
            print('no item')

i made a video showing how it seems like the faster i click the item the more accurately it works but if i click the item slowly it's not accurate.. so odd

here's the entire script: https://paste.pythondiscord.com/RIKA

you'll need a png icon to run the script.. i didn't add backup icon code to create its own image

looks like you can handle it more reliably if you disable the built-in selection behaviour with selectmode="none": ```py
from tkinter import Tk
from tkinter.ttk import Treeview

app = Tk()
tree = Treeview(app, show="tree", selectmode="none")
tree.pack(expand=True, fill="both")

for i in range(10):
tree.insert("", "end", text=f"Entry {i+1}")

def toggle_selection(event):
iid = tree.identify_row(event.y)
if iid not in tree.selection():
tree.selection_set(iid)
else:
tree.selection_set()

tree.bind("<1>", toggle_selection)
app.mainloop()```

assuming you don't need multi-select, that is
