DISPCONTAINERPREPAINTCALLBACK

#include "l_bitmap.h"

L_INT pEXT_CALLBACK YourFunction(hCellWnd, pCellInfo, pUserData)

Sets a callback function that is called before painting the cell or sub-cell.

Parameters

L_HWND hCellWnd

A handle to the window that represents the Medical Viewer Cell.

pDISPCONTAINERCELLINFO pCellInfo

Pointer to the DISPCONTAINERCELLINFO structure to be updated with the cell information.

L_VOID * 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

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

Comments
