class CairoPolygonDrawer(AbstractCairoDrawer):
Class that is used to draw polygons in Cairo.
The corner points of the polygon can be set by the points property of the drawer, or passed at construction time. Most drawing methods in this class also have an extra points argument that can be used to override the set of points in the points property.
Method | __init__ |
Constructs a new polygon drawer that draws on the given Cairo context. |
Method | draw |
Draws the polygon using the current stroke of the Cairo context. |
Method | draw_path |
Sets up a Cairo path for the outline of a polygon on the given Cairo context. |
