DISPCONTAINERMOUSECALLBACK

#include "l_bitmap.h"

L_INT pEXT_CALLBACK YourFunction(hCellWnd, uMessage, pCellInfo, pUserData)

Callback function that is called every time the user makes an action with the mouse.

Parameters

L_HWND hCellWnd

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 WM_LBUTTONDBLCLK WM_RBUTTONDBLCLK WM_MBUTTONDBLCLK WM_XBUTTONDBLCLK

pDISPCONTAINERCELLINFO pCellInfo

Pointer to the DISPCONTAINERCELLINFO information structure to be updated with the cell information.

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

Returns
