How to display text beside cursor in tkinter Listbox

Question

I have this few lines of code which print the selected content in the Listbox when double clicked but i want to display text beside the cursor like double click the selected content to print to prompt the user to take such action before it can be printed.

I search the listbox documentation and found the is an attribute cursor which you set the cursor type to display when the widget has focus but didn't find something like cursor-text to do that.Is the a way i can work around to achieve that, your suggestions are welcomed.

from tkinter import *


def test(event=None):
    print("woow test works")
    print(l.get(ACTIVE))


root = Tk()

l = Listbox(root, cursor="tcross")
l.pack()
l.insert(END, ("today"),("tomorrow"))
l.bind("<Double-Button-1>", test)

root.mainloop()

You might be able to implement what are called "tooltips" to do something like you want. See [this](https://stackoverflow.com/questions/3221956/how-do-i-display-tooltips-in-tkinter) for example. I think it would be at best very difficult, if not impossible, to do it with a `Listbox` by itself. — martineau, Apr 12 '18 at 17:41

I don't quite understand your English, but you can see this page for an example of using tooltips, which make text appear on mouse hover.

Yes, it's possible to add specific info or comments to listbox lines using Hovertip from idlelib.tooltip. In the example below, Mark Lutz's customizable scrolled listbox works normally, except that right-clicking on any line opens a tip with info/comments for that line. Ref. : Programming Python 4th ed. Example 9-9

from tkinter import *
from idlelib.tooltip import Hovertip

class ScrolledList(Frame):
    def __init__(self, options, parent=None):
        Frame.__init__(self, parent)    
        self.pack(expand=YES, fill=BOTH)
        botfrm = Frame(parent)
        botfrm.pack(side=BOTTOM)
        Label(botfrm,
            text="Select a line and right-click for info").pack()
        self.makeWidgets(options)
        self.myTip = None

    def handleList(self, event):
        if self.myTip:
            self.myTip.__del__()
        label = self.lstbx.get(ACTIVE)
        self.runCommand(label)

    def overflyLine(self, event):
        if self.myTip:
            self.myTip.__del__()
        self.myTip = Hovertip(self.lstbx,f"Comments for {self.lstbx.get(ACTIVE)}")
        self.myTip.showtip()

    def makeWidgets(self, options):
        sbar = Scrollbar(self)
        list = Listbox(self, relief=SUNKEN, bg='misty rose')
        sbar.config(command=list.yview)
        list.config(yscrollcommand=sbar.set)
        sbar.pack(side=RIGHT, fill=Y)
        list.pack(side=LEFT, expand=YES, fill=BOTH)
        for label in options:
            list.insert(END, label)
        self.lstbx = list
        list.bind('<Button-3>', self.overflyLine)
        list.bind('<Double-1>', self.handleList)
        list.bind('<Return>', self.handleList)

    def runCommand(self, selection):
        print('You selected:', selection)

if __name__ == '__main__':
    options = (('Lumberjack-%s' % x) for  x in range(20))
    scr = ScrolledList(options).mainloop()
