L_INT EXT_FUNCTION L_PntDrawShapeRectangle(pPaint, UserDC, prcRect)
pPAINTHANDLE pPaint; |
/* pointer to a paint handle */ |
HDC UserDC; |
/* handle to the device context */ |
LPRECT prcRect; |
/* pointer to a RECT structure */ |
Draws a rectangle using the specified points.
Parameter |
Description |
pPaint |
Pointer to a paint handle. |
UserDC |
Handle to a device context, such as a screen, to use as a display surface. This parameter can also be NULL. The mapping mode of the device context must be MM_TEXT. |
prcRect |
Pointer to a RECT structure that specifies the rectangle. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
The rectangle will be drawn using the current shape properties. To determine the current shape properties, call L_PntGetProperty. To set or change the current shape properties, call L_PntSetProperty. For more information on the shape properties, refer to the PAINTSHAPE structure.
If UserDC is not NULL, the toolkit will paint the rectangle on the specified device context. If UserDC is NULL, the rectangle will not be painted on a device context.
If a bitmap has been set using the L_PntSetMetrics function, the rectangle will be drawn on the specified bitmap. If UserDC is not NULL and a bitmap has been set using the L_PntSetMetrics function, then the rectangle will be drawn to both the device context and the bitmap.
