L_UINT uMessage;

/* message */

L_INT nX;

/* X mouse position */

L_INT nY;

nX

nY

A Value that represents the Y position of the cursor.

nCellIndex

A zero-based index of the cell that contains the annotation object.

nSubCellIndex

A zero-based index of the sub-cell that contains that annotation object.

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_DispContainerSetAnnotationCallBack.) 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.
