DISPCONTAINERPREPAINTCALLBACK

#include "l_bitmap.h"

L_INT pEXT_CALLBACK YourFunction(pCellInfo, pUserData)

pDISPCONTAINERCELLINFO pCellInfo;	/* pointer to a cell information structure */
L_VOID * pUserData;	/* pointer to more parameters for the callback */

Sets a callback function that is called before painting the cell or sub-cell. This function is available only in the Medical Imaging Suite toolkit.

Parameter	Description
pCellInfo	Pointer to the DISPCONTAINERCELLINFO structure to be updated with the cell information.
pUserData	A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of L_DispContainerSetPrePaintCallBack.) Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.

Returns

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

Comments

To get the post-paint callback, use L_DispContainerGetPostPaintCallBack. To set the post-paint callback, use L_DispContainerSetPostPaintCallBack.
