DISPCONTAINERMOUSECALLBACK

#include "l_bitmap.h"

L_INT pEXT_CALLBACK YourFunction(uMessage, pCellInfo, pUserData)

L_UINT uMessage;	/* message */
pDISPCONTAINERCELLINFO pCellInfo;	/* pointer to a cell information structure */
L_VOID * pUserData;	/* pointer to more parameters for the callback */

Callback function that is called every time the user makes an action with the mouse. This function is available only in the Medical Imaging Suite toolkit.

Parameter	Description
uMessage	Value that represents the message from the mouse. Possible values are:
	WM_LBUTTONDOWN
	WM_LBUTTONUP
	WM_MBUTTONDOWN
	WM_MBUTTONUP
	WM_MOUSEMOVE
	WM_RBUTTONDOWN
	WM_RBUTTONUP
	WM_LBUTTONDBLCLK
	WM_RBUTTONDBLCLK
	WM_MBUTTONDBLCLK
pCellInfo	Pointer to the DISPCONTAINERCELLINFO information structure to be updated with the cell information.
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

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.
