Name

create_polygon

Synopsis

                        c.create_polygon(*coordinates, **poly_options)

Creates a polygon item with vertices at the given coordinates and returns the item’s handle. coordinates must be an even number of positional parameters, alternately x and y values for each vertex of the polygon, and there must be at least six positional parameters (three vertices). poly_options may include:

fill

The polygon’s interior color (default is black)

outline

The polygon’s perimeter color (default is black)

smooth

If true, the polygon is drawn as a smooth curve (a B-spline); otherwise (default), the line is drawn as a normal polygon (a sequence of sides)

tags

A string (to assign a single tag to this item) or a tuple of strings (to assign multiple tags to this item)

width

Width of the perimeter line in pixels (default 1)

For example:

                        x=c.create_polygon(0,150, 50,100, 0,50, 50,0 fill='',  
                   outline='red')

draws two empty red triangles on c as a single polygon, and binds the polygon’s handle to variable x. You can then fill the triangles with blue using:

                        c.itemconfig(x,fill='blue')
