As the users will enter string in Entry box , we will offer matching options like Autocomplete by using one listbox and user can select any one option to fill the Entry box.
We will place the Listbox below the Entry widget and keep the ypad=0 so both widgets are placed one below the other.
We will change the Listbox background colour and active border colour same as window background colour to merge the layout of the Listbox with the window.
We will trigger and populate the listbox options by taking data from the source listbox , for this we will use one for loop to list all available options and use regular expression match method to get the strings ( options ) matching to the searched string.
Once the match() method returns true the element is added as option of the Listbox.
We can bind the Listbox selection to pass the selected option as input to Entry widget.

Hi There, Is it possable to load the ListBox with the LIST when you run the prgrame so the user can see whats on the list. Reagrds Phil

[@plus2net1]

By using Insert(). Check the code here. You can also use listvariable to connect to a Tuple, www.plus2net.com/python/tkinter-listbox.php

@@plus2net1 Thanks so much for your answer to my question it really makes the programme easier to use now we can see what’s on the list. Ps... I added a select button to create the variable to use in a function which goes to an Excel sheet as a criteria. Thank again and I look forward to learning more about Tinker with your tutorials and video’s. Regards Phil

❤️ 👍👍 Very Helpful. Sir can you make same thing on combobox only and combobox drop down as list

[@plus2net1]

I replied to other question pointing to this. There are some issues using Combobox , we will try again.

Peace be upon you, sir. Is it possible to add to the class AutocompleteEntry properties such as : background="red" , foreground="yellow" , border=0 ,? Please help I am trying to add these features and unfortunately I get an error

[@plus2net1]

Hi, Yes can be added, All the options are displayed using one Listbox , so the properties of the listbox can be changed. Check here how to manage them . www.plus2net.com/python/tkinter-listbox.php Here properties like bg ( background colour ) and fg ( font color ) can be managed. Here while creating the listbox you can manage or by using config() you can update them. Hope this helps .

@@plus2net1 Unfortunately I tried to update it using the config class and unfortunately I get an error,, and at the same time I tried to add properties to the AutocompleteEntry class in this way.... self.data_entry = AutocompleteEntry (self.root , backaground="red" , forground="yellow" , border=0 ) Unfortunately, I tried to update it using the config class, and unfortunately I get an error,, at the same time I tried to add properties to the AutocompleteEntry class in this way .... Unfortunately, I get an error saying that the AutocompleteEntry class does not contain a backaground property and also does not contain a foreground property Sir, I need to change the color The background of the input field, as well as changing the edges of the input field so that I put this field inside the Label I hope you can solve this matter or write a small code and send it to me I will be very thankful to you

@@ajm0o AutocompleteEntry is a different library and it has different properties, In the above tutorial two widgets are used , one is Entry box and other one is Listbox , so properties supported by these widgets can't work with different library widget. So try to use the properties supported by AutocompleteEntry library and work with it, Or change to Entry and Listbox as explained here. Hope this concept is clear.

How do I get the result from the combo box to use as a varable, after I run the programe

[@plus2net1]

e1_str holds the value, so this can be internally used ( it is a sringvar so value is e1_str.get() ) or in other applications it can be accessed by from autocomplete import e1_str

@@plus2net1 Thank you for taking the time to reply. Your solution works just fine and I can now get the string I was looking for by using the import method. Keep up the good work Regards Phil
