Parameter

Description

hCellWnd

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

pfnCallBack

Callback function that is called every time the container indicates there has been a mouse or keyboard event that is associated with a user-defined action.

The callback function must adhere to the function prototype described in DISPCONTAINERACTIONCALLBACK.

pUserData

Void pointer that you can use to pass one or more additional parameters that the callback function needs.

To use this feature, assign a value to a variable or create a structure that contains as many fields as you need. Then, in this parameter, pass the address of the variable or structure, casting it to L_VOID *. The callback function, which receives the address in its own pUserData parameter, can cast it to a pointer of the appropriate data type to access your variable or structure.

If the additional parameters are not needed, you can pass NULL in this parameter.

The function was successful.
