Today, we continue our course about create a tkinter application with Python. We are going to learn these 3 widgets : Input; Text; Canvas.

So, if you don't have already see the others part of the course, let's watch this.

Input:

An input widget is a single line entry. We can create with like this :

input_widget = Input(app)
input_widget.pack()

And like the Label and Button widgets, you can add the arguments about text : fg, bg, font, width, height. The width isn't in pixel in character.

Text:

Now, a Text widget is an input but more wider then the Input because you can, like a notepad, write on multiple lines.

text = Text(app)
text.pack()

Same arguments for text, ect...

Canvas:

A Canvas is a surface where you can draw or place images.
For an image :

canv = Canvas(app, width=500, height=300, bg="white") # width, height in pixels
img = PhotoImage(file="image.png") # Here we load an image
canv.create_image(250, 150, image = img) # 250 -> position x, 150 -> position Y
canv.pack()

You must know that the 0;0 in a canvas isn't at the middle of it but in the left top corner.

For a circle :

canv = Canvas(app, width=500, height=300, bg="white")
canv.create_circle(200, 100, 300, 200) # (x0, y0, x1, y1)
canv.pack()

Now, you know the main widgets of Tkinter. In the next post, we'll see the bind method and the command argument in Button widget. And this course will be finish.
So, have a nice day. And see you soon. Bye ! 👋👨‍💻
