How to draw a dashed line on a Tkinter canvas?

TkinterPythonGUI-Programming

To draw a dashed line on a Tkinter canvas, we can use the dash parameter of create_line() method.

Steps −

  • Import the tkinter library and create an instance of tkinter frame.

  • Set the size of the frame using geometry method.

  • Create a Canvas widget and set its height and width.

  • Next, use the create_line function and pass the coordinates of the line (x1, y1) and (x2, y2).

  • To get a dashed line, use the dash parameter dash=(5,1) for 5px dash followed by 1px space.

  • You can set the color and width of the dashed lines using the fill and width parameters.

  • Finally, run the mainloop of the application window.

Example

# Import the library
from tkinter import *

# Create an instance of window
win = Tk()

# Set the geometry of the window
win.geometry("700x350")

C1 = Canvas(win, width=600, height=400)

# Coordinates of the line
coordinates = 100,150,550,150

# Draw a dashed vertical line, 5px dash and 1px space
C1.create_line(coordinates, dash=(5,1))
C1.pack()

win.mainloop()

Output

It will produce the following output −

Note: Dash patterns are system-dependent. You may get different outputs on Windows and Linux based systems. Windows doesn't support the same dash patterns as Linux.
