BOOL DrawEdge( LPRECT lpRect, UINT nEdge, UINT nFlags );
DrawEdge函数自动调用系统相关颜色绘制!无法自行设置颜色!!
返回值
Nonzero if successful; otherwise 0.
如果成功,则返回非零值,否则为0。
参数说明
lpRect
A pointer to a RECT structure that contains the logical coordinates of the rectangle.
指向包含有逻辑坐标矩形的RECT结构的指针。
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.
指定矩形内外边界的类型。该参数是内边界标志和外边界标志的集合。请参阅说明中该参数的类型。
nFlags
The flags that specify the type of border to be drawn. See the Remarks section for a table of the parameter’s values:
指定绘制边界的类型,请参阅说明中该参数的类型。
备注
Call this member function to draw the edges of a rectangle of the specified type and style.
调用该成员函数,绘制指定风格和类型的矩形。
The inner and outer border flags are as follows:
内外边界标志如下:
- Inner-border flags 内边界标志
- BDR_RAISEDINNER Raised inner edge.
内边界凸出。 - BDR_SUNKENINNER Sunken inner edge.
内边界凹下。
- BDR_RAISEDINNER Raised inner edge.
- Outer-border flags外边界标志
- BDR_RAISEDOUTER Raised outer edge. 外边界凸出。
- BDR_SUNKENOUTER Sunken outer edge.
外边界凹下
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:
参数必须是内边界标志和外边界标志的组合。可以为以下值之一:
- 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:
NFlags参数的类型如下:
- BF_RECT Entire border rectangle.
矩形的四周边界。 - BF_LEFT Left side of border rectangle.
矩形的左边界。 - BF_BOTTOM Bottom of border rectangle.
矩形的底部边界 - BF_RIGHT Right side of border rectangle.
矩形的右边界。 - BF_TOP Top of border rectangle.
矩形的顶部边界。 - BF_TOPLEFT Top and left side of border rectangle.
矩形的左、底部边界。 - BF_TOPRIGHT Top and right side of border rectangle.
矩形的右、顶部边界。 - BF_BOTTOMLEFT Bottom and left side of border rectangle.
矩形的左、底部边界。 - BF_BOTTOMRIGHT Bottom and right side of border rectangle.
矩形的右、底部边界。
For diagonal lines, the BF_RECT flags specify the end point of the vector bounded by the rectangle parameter.
对于对角线,BF_RECT标志指定了矢量终点:
- BF_DIAGONAL_ENDBOTTOMLEFT Diagonal border. The end point is the bottom-left corner of the rectangle; the origin is top-right corner.
BF_DIAGONAL_ENDBOTTOMLEFT 对角线边界。终点为矩形的左下角,始点为右上角。 - BF_DIAGONAL_ENDBOTTOMRIGHT Diagonal border. The end point is the bottom-right corner of the rectangle; the origin is top-left corner.
BF_DIAGONAL_ENDBOTTOMRIGHT 对角线边界。终点为矩形的右下角,始点为左下角。 - BF_DIAGONAL_ENDTOPLEFT Diagonal border. The end point is the top-left corner of the rectangle; the origin is bottom-right corner.
BF_DIAGONAL_ENDTOPLEFT 对角线边界。终点为矩形的左上角,始点为右下角。 - BF_DIAGONAL_ENDTOPRIGHT Diagonal border. The end point is the top-right corner of the rectangle; the origin is bottom-left corner.
BF_DIAGONAL_ENDTOPRIGHT 对角线边界。终点为矩形的右上角,始点为左下角。
