Sets a callback function that is called before painting the cell or sub-cell.
A handle to the window that represents the Medical Viewer Cell.
Pointer to the DISPCONTAINERCELLINFO structure to be updated with the cell information.
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.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
