Python Tkinter Combobox

A Python Tkinter Combobox is a drop-down list that allows the user to select a value from a list. The list of values is defined by the “values” option, and the currently selected value is stored in the “textvariable” option. The Combobox widget is a combination of an Entry widget and a Listbox widget.

Here’s an example of how to create a Tkinter Combobox:

 

This code will create a Tkinter window with a Combobox that has the options “Option 1”, “Option 2”, and “Option 3”. The currently selected value is stored in the “selected” variable, which can be used to retrieve the value and use it in your program.

Here’s an example of how you can add a label that displays the selected item from the Combobox:

 

In this code, I’ve added a label after the Combobox, and set its textvariable to be the same as the Combobox’s textvariable. This means that whenever the user selects a new item from the Combobox, the label will automatically update to display the selected item.

You can also add a function to update the label when you change the combobox selection using the command attribute of the combobox, like this:

 

Now, the label will display the selected option from the combobox every time you change the selection.

Here is an example of a simple weather application using Tkinter and OOP (Object-Oriented Programming) in Python:

 

 

In this example, the WeatherApp class is defined which inherits from the tk.Tk class. In the __init__ method, various widgets such as labels, a combobox, and a button are created and placed on the GUI using the grid layout manager. The combobox is populated with a list of cities and is set to be “readonly” so that the user can only select one of the options provided. The button is configured to call the get_weather method when clicked.

The get_weather method retrieves the currently selected city from the combobox and uses an if loop.
