L_PntBrushMoveTo

#include "LtPnt.h"

L_INT EXT_FUNCTION L_PntBrushMoveTo(pPaint, UserDC, nX, nY)

pPAINTHANDLE pPaint;	/* pointer to a paint handle */
HDC UserDC;	/* handle to the device context */
L_INT nX;	/* x position */
L_INT nY;	/* y position */

Updates the current position of the paintbrush and paints a single brush touch.

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.
nX	Specifies the x-coordinate of the new position.
nY	Specifies the y-coordinate of the new position.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

The paintbrush touch will be drawn using the current paintbrush properties. To determine the current paintbrush properties, call L_PntGetProperty. To set or change the current paintbrush properties, call L_PntSetProperty. For more information on the paintbrush properties, refer to the PAINTBRUSH structure.

If UserDC is not NULL, the toolkit will paint the paintbrush touch on the specified device context. If UserDC is NULL, the paintbrush touch will not be painted on a device context.

If a bitmap has been set using the L_PntSetMetrics function, the paintbrush touch 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 paintbrush touch will be drawn to both the device context and the bitmap.
