DISPCONTAINERACTIVESUBCELLCHANGED

Summary

This callback function is called every time the user changes the active sub-cell.

Syntax

#include "ltivw.h"

L_INT pEXT_CALLBACK YourFunction(hCellWnd, nCellIndex, nSubCellIndex, nPreviousSubCellIndex, pUserData)

Parameters

L_HWND hCellWnd

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

L_INT nCellIndex

A zero-based index of the cell, that contains the sub-cell that been changed.

L_INT nSubCellIndex

A zero-based index of the new active sub-cell.

L_INT nPreviousSubCellIndex

A zero-based index of the sub-cell that was active before changing the active sub-cell index.

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_DispContainerSetActiveSubCellChangedCallBack.) Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.

Returns
