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.

Parameter	Description
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
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.
