Keyboard Event Binding With tKinter - Python Tkinter GUI Tutorial #44

In this video I'll show you how to do keyboard event binding with tKinter.
Up until not we've run functions by passing a command to a button, but there's a better way to capture keyboard and mouse events in tKinter...binding!
Binding allows us to grab keyboard and mouse events...so mouse clicks (left or right mouse clicks), keyboard presses (Say, if you pressed the q key on your keyboard) and much more.

Hello Sir. if we want to assign a particular key in our keyboard to trigger an event what modifications we must do??

[@rorydaines3176]

Hey man love your videos, thumbs up. I just one question though, on creating this event the original function ceases to work. I have an exercise where my Spinbox has the command function but I also want the return key to work to call my function. However when I create the even, my spinbox command call stops working and creates an error of , TypeError: unit_price() missing 1 required positional argument: 'event' So was wondering how I can incorporate both into my program. Hope you see this, thanks again.

Is there a way to fix it or go around it?

[@maxwellhawk]

Hey. I really need help. I have few Labels that suppose to change color when u hover mouse over it. I use bind bc I haven't find any other way to use widget like Label interactive, it also react on click, and do particular stuff. My problem that when I create a function for changing color, I must make 2 functions - on is other and I have at least 3 labels, so it has to be 6 function. That looks very long and unprofessional. I was trying just to run code like LabelName.configure(bg="red') instead of handler but it doesn't work. It accept only commands - function. And it pass in that function - event. So i was wonder is there a way to make 2 function and somehow pass in them name of the widget which pretty much an object than use it to execute color change code?

[@Codemycom]

1. who cares how it looks? 2. Sure, you can use a lambda to pass in the widget itself or some sort of identifier that you can use in your function with logic to do whatever you want. Google: tkinter bind pass arguments (or something like that)

[@maxwellhawk]

@@Codemycom 1. I care. I wanna be a pro. eventually. So it is always a good idea optimize code. 2. Yes. we used [lambda: function] before. All i had to do is just make single line function instead and it worked. I just add name of the function and it start working. Looks like this Labelname.bind(, lambda x: Labelname.configure(bg="red")) It's not exactly what I wanted though. I wanted to write X.configure(bg="red")) only once and just send name of Label widget into X.

I managed to change the color of the title bars to that blue hue but the gradient is not available in Windows 10 apparently so I've been trying to find a way to fake it by maybe finding a python module that can display a Windows 10 program running inside of a widget this might not exist though
