◆ Polygon() [3/8]
◆ Polygon() [4/8]
construct the polyogn from a sequence of consecutive lines.
- Parameters
-
| linetrain | The line segments that define the polygon. The ctor assumes that the end point of each segment is equal to the start point of the next segment, without checking this assumption. |

◆ append() [1/2]
extend the polygon by adding a point at the end.
- Parameters
-
| pt | The additional point to be appended. |

◆ append() [2/2]
◆ boundingRect() [1/2]
Returns the bounding rectangle of the polygon, or Nice::Rect(0,0,0,0) if the polygon is empty.

◆ containsPoint() [1/2]
- Since
- 4.3
Returns true if the given point is inside the polygon according to the specified fillRule; otherwise returns false.
◆ containsPoint() [2/2]
◆ intersect() [1/2]
Check whether any of the line segments intersects with another polygon.
All line segments of this are checked for intersection with the line segments of the other polygon.
- Parameters
-
- Returns
- NoIntersection if no lines intersect, BoundedIntersection if some touch. Note that NoIntersection is also returned if one polygon is entirely within another.

retrieve the idx-th line segment.
- Parameters
-
| idx | The 0-based line segment |
- Returns
- The line starting at point idx. If the idx is outside the range of known points, a null line (as defined by Nice, whatever that might be) is returned
