DISPCONTAINERANNOTATIONCALLBACK (original) (raw)

Summary

This callback function is called every time the user clicks on an annotation object.

Syntax

#include "ltivw.h"

L_INT pEXT_CALLBACK YourFunction(nCellIndex, uMessage, nX, nY, nCellIndex, nSubCellIndex, pUserData)

Parameters

HWND nCellIndex

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

L_UINT uMessage

Value that represents the message from the mouse. Possible values are:

WM_LBUTTONDOWN WM_LBUTTONUP WM_MBUTTONDOWN WM_MBUTTONUP WM_XBUTTONDOWN WM_XBUTTONUP WM_MOUSEMOVE WM_RBUTTONDOWN WM_RBUTTONUP

L_INT nX

A Value that represents the X position of the cursor.

L_INT nY

A Value that represents the Y position of the cursor.

HWND nCellIndex

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

L_INT nSubCellIndex

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

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