Detailed Description

Since sg.Tree doesn't appear to have the option 'right_click_selects', I'm looking for the simplest code to do the same thing.

Full Disclosure: I saw another thread where someone was able to do this, but the code was doing a bunch of other stuff in addition that I didn't understand. I wasn't able to distill the lines of code needed to just do the right_click_selects for a Tree.

Hopefully right_click_selects option can be added to sg.Tree in the future.

If you care to share something about your project, it would be awesome to hear what you're building.

Not sure if it is same as in Table element, or more complex.

Following demo the right-click-selection for Tree element, but with tkinter code.

import PySimpleGUI as sg

def right_click_selection(element, event):
    widget = element.widget
    region = widget.identify('region', event.x, event.y)
    if region in ('cell', 'tree'):
        item = widget.identify_row(event.y)
        key = element.IdToKey[item]
        widget.selection_set([item])            # Only one item selected
        # widget.selection_toggle([item])       # toggole selection of one item
        """
        if isinstance(key, int):                # to get the text of item by the key defined by user when treedata.insert called
            print(data[key][0])
        else:
            k0, k1 = key
            print(data[k0][1][k1])
        """

treedata = sg.TreeData()
data = [
    ['Fruit',     ['Apple', 'Mongo']],
    ['Seasoning', ['Cat', 'Dog', 'Tiger']],
    ['Meat', ['Pork', 'Beef', 'Fish']],
    ['Vegetable', ['Broccoli', 'Cabbages', 'Mushrooms']],
]
for i, first in enumerate(data):
    treedata.Insert('', i, first[0], values=[])         # key defined as integer, i
    for j, second in enumerate(first[1]):
        treedata.Insert(i, (i, j), second, values=[])   # key defined as a 2-tuple, (i, j)

font = ('Courier New', 11)
sg.set_options(font=font)

layout = [
    [sg.Tree(data=treedata, headings=['Unit', 'Unit Price'], show_expanded=True,
     col0_width=15, enable_events=True, visible_column_map=[False,], key='TREE')],
]
window = sg.Window('Title', layout, finalize=True)
tree = window['TREE']
tree.widget.configure(show='tree')  # Hide header
tree.bind('<Button-2>' if sg.running_mac() else '<Button-3>', ' Right Click')   # Bind right button

while True:

    event, values = window.read()
    if event == sg.WIN_CLOSED:
        break
    elif event == 'TREE Right Click':
        right_click_selection(tree, tree.user_bind_event)

window.close()

[PySimpleGUI]

Should this be added as an enhancement? What's your opinion Jason?

[Jason Yang]

Not sure why option right_key_selects required for ? Left key selects not work ?
There're lot of different requirements and it's impossible to build everything for people.

@jason990420 , thank you so much for this bit of code. It worked great!
@PySimpleGUI , I believe this should be an enhancement. The reason being that sg.Tree currently allows a right_click_menu. BUT without the right_click_select, the menu is much less useful and predictable. It's counterintuitive to be able to right click on a tree item, pick the menu, and not have it act on the line that was right clicked on. I hope that makes sense.

You've got that right!

@rtl19 I do understand what you're saying in how it currently works and can be better.
