CDC::DrawEdge
BOOL DrawEdge( LPRECT lpRect, UINT nEdge, UINT nFlags );
Return Value
Nonzero if successful; otherwise 0.
Parameters
lpRect
A pointer to a RECT structure that contains the logical coordinates of the rectangle.
nEdge
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. See the Remarks section for a table of the parameter’s types.
nFlags
The flags that specify the type of border to be drawn. See the Remarks section for a table of the parameter’s values:
Remarks
Call this member function to draw the edges of a rectangle of the specified type and style.
The inner and outer border flags are as follows:
Inner-border flags
BDR_RAISEDINNER Raised inner edge.
BDR_SUNKENINNER Sunken inner edge.
Outer-border flags
BDR_RAISEDOUTER Raised outer edge.
BDR_SUNKENOUTER Sunken outer edge.
The nEdge parameter must be a combination of one inner and one outer border flag. The nEdge parameter can specify one of the following flags:
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.
The nFlags parameter types are as follows:
BF_RECT Entire border rectangle.
BF_LEFT Left side of border rectangle.
BF_BOTTOM Bottom of border rectangle.
BF_RIGHT Right side of border rectangle.
BF_TOP Top of border rectangle.
BF_TOPLEFT Top and left side of border rectangle.
BF_TOPRIGHT Top and right side of border rectangle.
BF_BOTTOMLEFT Bottom and left side of border rectangle.
BF_BOTTOMRIGHT Bottom and right side of border rectangle.
For diagonal lines, the BF_RECT flags specify the end point of the vector bounded by the rectangle parameter.
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.
