Build A Tkinter App (Part 2 / Widgets-2) - Python

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()

So, have a nice day. And see you soon. Bye ! 👋👨‍💻
