class PolygonDrawer(AbstractCairoDrawer):
Class that is used to draw polygons.
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 |
Sets up a Cairo path for the outline of a polygon on the given Cairo context. |
| Instance Variable | points |
Undocumented |
Inherited from AbstractCairoDrawer:
| Method | bbox |
Sets the bounding box of the drawing area where this drawer will draw. |
| Instance Variable | context |
Undocumented |
| Property | bbox |
The bounding box of the drawing area where this drawer will draw. |
| Method | _mark |
Marks the given point with a small circle on the canvas. Used primarily for debugging purposes. |
| Instance Variable | _bbox |
Undocumented |
Constructs a new polygon drawer that draws on the given Cairo context.
| Parameters | |
| context | the Cairo context to draw on |
| bbox | ignored, leave it at its default value |
| points | the list of corner points |
Draws the polygon using the current stroke of the Cairo context.
| Parameters | |
| points | the coordinates of the corners of the polygon, in clockwise or counter-clockwise order, or None if we are about to use the points property of the class. |
Sets up a Cairo path for the outline of a polygon on the given Cairo context.
| Parameters | |
| points | the coordinates of the corners of the polygon, in clockwise or counter-clockwise order, or None if we are about to use the points property of the class. |
| corner | if zero, an ordinary polygon will be drawn. If positive, the corners of the polygon will be rounded with the given radius. |
