Parameter |
Description |
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. |
nX |
Specifies the x-coordinate of the new position. |
nY |
Specifies the y-coordinate of the new position. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes |
The current position, which serves as the starting point for this function, is set using the LRasterPaint::BrushMoveTo function. If LRasterPaint::BrushMoveTo is not been called before LRasterPaint::BrushLineTo, the default starting point is (0, 0).
The paintbrush stroke will be drawn using the current paintbrush properties. To determine the current paintbrush properties, call LRasterPaint::GetProperty. To set or change the current shape properties, call LRasterPaint::SetProperty. For more information on the shape properties, refer to the PAINTBRUSH structure.
If UserDC is not NULL, the toolkit will paint the paintbrush stroke on the specified device context. If UserDC is NULL, the paintbrush stroke will not be painted on a device context.
If a bitmap has been set using the LRasterPaint::SetMetrics function, the paintbrush stroke will be drawn on the specified bitmap. If UserDC is not NULL and a bitmap has been set using the LRasterPaint::SetMetrics function, then the paintbrush stroke will be drawn to both the device context and the bitmap.
