Hardware Required

Example Code

Instantiate an object of the GUI class within the UNIHIKER class, and call the draw_rect() function through this object to display the rectangle and set the parameters. 

from unihiker import GUI   # Import the package
gui = GUI()  # Instantiate the GUI class

# Draw a rectangle on the GUI with the specified coordinates and parameters
# The rectangle is located at (x=80, y=110) with a width of 80 pixels and a height of 60 pixels
# The outline of the rectangle has a width of 3 pixels
# The color of the rectangle is specified as (0, 0, 255), representing an RGB color value (blue)
# When the rectangle is clicked, the lambda function is executed, which prints "rect clicked" to the console
gui.draw_rect(x=80, y=110, w=80, h=60, width=3, color=(0, 0, 255), onclick=lambda: print("rect clicked"))

import time
while True:
    # Add a delay to prevent the program from exiting and to observe the effects
