I am creating a program that requires changing the colour of a polygon using tkintermapview during the program. I have tried the following:
polygon1 = map_widget.set_polygon([(52, -1),
(52.5, -1.1),
(52.2, -1.5)],
fill_color = 'red',
name='Test location')
polygon1.fill_color = 'black'
print(polygon1.fill_color)
output:
'black'
However, the colour on the map does not change from red to black. How would I achieve the desired outcome?
