DISPCONTAINERBUILTINTAGCALLBACK

#include "ltivw.h"

L_INT pEXT_CALLBACK YourFunction(hCellWnd, nSubCellIndex, uTagType, pString, pUserData)

This callback is called before printing any built-in tag text.

Parameters

L_HWND hCellWnd

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

L_INT nSubCellIndex

A zero-based index of the sub-cell. This sub-cell contains the image that contains the region changed. Pass -2 to refer to the selected sub-cell.

L_UINT uTagType

The built-in tag that is about to be printed on the cell/sub-cell. Possible values are:

L_TCHAR * pString

A string containing the built-in tag text, the user can update this value to display instead.

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

Returns

Comments

To get the built-in tag callback, use L_DispContainerGetBuiltInTagCallBack. To set the built-in tag callback, use L_DispContainerSetBuiltInTagCallBack.
