Detailed Description
2D Rectangle.
Member Function Documentation
§ doIntersection()
| bool URect::doIntersection | ( | const URect & | clip2 | ) |
performs the intersection with the rectangle that is given as an argument.
returns false if there is no intersection (this rectangle is then left unchanged)
§ doUnion()
| void URect::doUnion | ( | const URect & | clip2 | ) |
performs the union with the rectangle that is given as an argument.
Note: empty regions are not taken into account.
