#loop through all the buttons to enable or disable each one My_w.geometry("300x200") # Size of the window This list will be used to loop through and enable or disable each buttons by using the value of var ( the button which is clicked ) To do this we have to store the reference of the buttons in a list as these buttons are created dynamically. When some other button is clicked then the previous button will be enabled and the new button will be disabled. In above code we will add a feature that after the click of the button the sting of the button will be displayed and the button will be disabled for further click. List_languages = ("PHP","Python","HTML","Tkinter")ītn = tk.Button(my_w, text=language, command=lambda lan=language:show_lan(lan)) We will create one button for each element of a tuple of strings, on click of the button the string assigned to the button will be passed to another function and this function will display the string using one Label.
My_w.mainloop() # Keep the window open Using string variables L1 = tk.Label(my_w, textvariable=my_str, width=10 )Į = Button(my_w, text=j,command=lambda k=j: my_fun(k)) So each button ( time ) we will assign the value to another variable to pass it through loop. Note that the value we can’t use directly as it will always store the last value of the loop. We can read the value written on the button and display the same on button click. My_w.mainloop() # Keep the window open Reading the data written on the button My_w.geometry("200x200") # Size of the window
The text on the buttons should display the (unique ) number of the button. We can set a variable to any integer and based on this value, number of buttons will be created. Such requirements may occur when we are not sure how many buttons are required and how the events are to be handled. Tkinter dynamic buttons creation using range or a list with button reference managementīuttons can be created dynamically and can be referred for handling click events.
