how do i define the height of rectangle?-CodePudding

"Create a rectangle with coordinates x1=15, y1=20, width=120, height=150" Does it have to do something with the coordinates? Cause there's no 'height' option

from tkinter import *
window = Tk()
root.geometry("300x300")

canv = Canvas(window, width=200, height=250, bg="white")
canv.pack(pady=15)

coords = [15, 20, 0, 0]
rect = canvas.create_rectangle(coords, width=120)
window.mainloop()```

CodePudding user response：

Yes, your coords define the positions of two opposite corners of the rectangle, [x1, y1, x2, y2]. You have the coordinates of the top left corner already, so you need to figure out the coordinates of the bottom right corner using the given height and width - you simply add these to the coordinates.

In this example you simply would change your coords from [15, 20, 0, 0] to [15, 20, 135, 170].

One thing to note is that the coordinate system in Tkinter is defined with (0,0) at the top left of the window, so a higher y coordinate means further down the window and higher x coordinate means further right.

The coordinates are how you define the height and width of the rectangle. No height definition is required.

Python Tkinter Canvas Rectangle

Python Tkinter Canvas has built-in features to create shapes.
To create a rectangle create_rectangle() method is used.
This method accepts 4 parameters x1, y1, x2, y2. Here x1 and y1 are the coordinates for the top left corner and x2 and y2 are the coordinates for the bottom right corner.
