What is TKinter ComboBox?
Tkinter ComboBox, also known as a dropdown list or a combobox, is a user interface element that allows users to select an item from a list of predefined options. It combines the features of a text entry field and a listbox, and it provides users to choose from a set of choices.
In Tkinter ComboBox is implemented using ttk.Combobox widget from the ttk module, which stands for “themed Tkinter.” This widget provides more modern look and feel compared to the traditional Tkinter widgets. TKinter ComboBox widget typically consists of an entry field where users can type text or select an option from the dropdown list by clicking on a small arrow button. When the arrow button is clicked, the dropdown list expands to display the available options, and users can select one of them.

This line of code is for creating object of TKinter window.

window = tk.Tk() |
In these lines of codes we set the size of our window, also title with icon. make sure that have an icon in your project directory.

window.minsize(600, 400) window.title("Codeloop - Tkinter Combobox") window.iconphoto(True, tk.PhotoImage(file='codeloop.png')) |
This method is for click events that we are going to handle, the click events of button and you will see that we connect this method to our button, also we have created a label.

def chosingNumbers(): label.configure(text = "You Have Choosed " + mynumber.get()) label = ttk.Label(window, text = "Choose A Number") label.grid(column = 0, row = 0) |

combobox = ttk.Combobox(window, width = 15 , textvariable = mynumber) combobox['values'] = (5,6,7,8,9,10,12,14,15) combobox.grid(column = 1, row = 0) |
Also we have created a button because we want to handle the click events. and if you remember, now we connect our def chosingNumbers() method in here.

button = ttk.Button(window, text = "Click Me", command = chosingNumbers) button.grid(column = 1, row = 1) |
