CRgn Class Members
Construction
| CRgn | Constructs a CRgn object. |
Initialization
| CreateRectRgn | Initializes a CRgn object with a rectangular region. |
| CreateRectRgnIndirect | Initializes a CRgn object with a rectangular region defined by a RECT structure. |
| CreateEllipticRgn | Initializes a CRgn object with an elliptical region. |
| CreateEllipticRgnIndirect | Initializes a CRgn object with an elliptical region defined by a RECT structure. |
| CreatePolygonRgn | Initializes a CRgn object with a polygonal region. The system closes the polygon automatically, if necessary, by drawing a line from the last vertex to the first. |
| CreatePolyPolygonRgn | Initializes a CRgn object with a region consisting of a series of closed polygons. The polygons may be disjoint, or they may overlap. |
| CreateRoundRectRgn | Initializes a CRgn object with a rectangular region with rounded corners. |
| CombineRgn | Sets a CRgn object so that it is equivalent to the union of two specified CRgn objects. |
| CopyRgn | Sets a CRgn object so that it is a copy of a specified CRgn object. |
| CreateFromPath | Creates a region from the path that is selected into the given device context. |
| CreateFromData | Creates a region from the given region and transformation data. |
Operations
| EqualRgn | Checks two CRgn objects to determine whether they are equivalent. |
| FromHandle | Returns a pointer to a CRgn object when given a handle to a Windows region. |
| GetRegionData | Fills the specified buffer with data describing the given region. |
| GetRgnBox | Retrieves the coordinates of the bounding rectangle of a CRgn object. |
| OffsetRgn | Moves a CRgn object by the specified offsets. |
| PtInRegion | Determines whether a specified point is in the region. |
| RectInRegion | Determines whether any part of a specified rectangle is within the boundaries of the region. |
| SetRectRgn | Sets the CRgn object to the specified rectangular region. |
Operators
| operator HRGN | Returns the Windows handle contained in the CRgn object. |
