The DrawEdge function draws one or more edges of rectangle.
BOOL DrawEdge(
| HDC hdc, | // handle to device context |
| LPRECT qrc, | // pointer to rectangle coordinates |
| UINT edge, | // type of inner and outer edge to draw |
| UINT grfFlags | // type of border |
| ); |
Parameters
hdc
Identifies the device context.
qrc
Points to a RECT structure that contains the logical coordinates of the rectangle.edge
Specifies the type of inner and outer edge to draw. This parameter must be a combination of one inner-border flag and one outer-border flag. The inner-border flags are as follows:
| Value | Meaning |
| BDR_RAISEDINNER | Raised inner edge. |
| BDR_SUNKENINNER | Sunken inner edge. |
The outer-border flags are as follows:
| Value | Meaning |
| BDR_RAISEDOUTER | Raised outer edge. |
| BDR_SUNKENOUTER | Sunken outer edge. |
Alternatively, the edge parameter can specify one of the following flags:
| Value | Meaning |
| EDGE_BUMP | Combination of BDR_RAISEDOUTER and BDR_SUNKENINNER. |
| EDGE_ETCHED | Combination of BDR_SUNKENOUTER and BDR_RAISEDINNER. |
| EDGE_RAISED | Combination of BDR_RAISEDOUTER and BDR_RAISEDINNER. |
| EDGE_SUNKEN | Combination of BDR_SUNKENOUTER and BDR_SUNKENINNER. |
grfFlags
Specifies the type of border. This parameter can be a combination of these values:
| Value | Meaning |
| BF_ADJUST | Rectangle to be adjusted to leave space for client area. |
| BF_BOTTOM | Bottom of border rectangle. |
| BF_BOTTOMLEFT | Bottom and left side of border rectangle. |
| BF_BOTTOMRIGHT | Bottom and right side of border rectangle. |
| BF_DIAGONAL | Diagonal border. |
| BF_DIAGONAL_ENDBOTTOMLEFT | Diagonal border. The end point is the bottom-left corner of the rectangle; the origin is top-right corner. |
| BF_DIAGONAL_ENDBOTTOMRIGHT | Diagonal border. The end point is the bottom-right corner of the rectangle; the origin is top-left corner. |
| BF_DIAGONAL_ENDTOPLEFT | Diagonal border. The end point is the top-left corner of the rectangle; the origin is bottom-right corner. |
| BF_DIAGONAL_ENDTOPRIGHT | Diagonal border. The end point is the top-right corner of the rectangle; the origin is bottom-left corner. |
| BF_FLAT | Flat border. |
| BF_LEFT | Left side of border rectangle. |
| BF_MIDDLE | Interior of rectangle to be filled. |
| BF_MONO | One-dimensional border. |
| BF_RECT | Entire border rectangle. |
| BF_RIGHT | Right side of border rectangle. |
| BF_SOFT | Soft buttons instead of tiles. |
| BF_TOP | Top of border rectangle. |
| BF_TOPLEFT | Top and left side of border rectangle. |
| BF_TOPRIGHT | Top and right side of border rectangle. |
