typedef BOOL (ACCUAPI *LPFNIG_ART_SELECTNOTIFYFUNC)( HIGEAR hIGear, LPVOID lpPrivate, ART_MARK_INDEX hMarkIndex, BOOL fSelect );

Arguments:

Name	Type	Description
hIGear	HIGEAR	HIGEAR handle of an image.
lpPrivate	LPVOID	A far pointer to the private callback data.
hMarkIndex	ART_MARK_INDEX	The index for the selected mark.
fSelect	BOOL	A flag of type BOOL indicating the new selection state (selected/unselected).

Return Value:

Sample:

None

Example:

	Copy Code
BOOL ACCUAPI ARTSelectNotify( HIGEAR hIGear, LPVOID lpPrivate, ART_MARK_INDEX hMarkIndex, BOOL fSelect) { ART_MARK_ATTRIBUTES ma; ART_mark_query(hIGear, hMarkIndex, &ma); if (ma.dwType == ART_MARK_BUTTON && fSelect == TRUE) { /* prevent button marks from being selected */ return FALSE; } return TRUE; }

Copy Code

BOOL ACCUAPI ARTSelectNotify(        HIGEAR hIGear, LPVOID 
lpPrivate, ART_MARK_INDEX hMarkIndex, BOOL fSelect)
{
ART_MARK_ATTRIBUTES  ma;
ART_mark_query(hIGear, hMarkIndex, &ma);
if (ma.dwType == ART_MARK_BUTTON && fSelect == TRUE)
{
    /* prevent button marks from being selected */
    return FALSE;
}
return TRUE;
}

Remarks:

If the callback function returns FALSE, the mark's selection state is not changed. It returns TRUE to allow the selection state to be changed.

In order to use this callback, it must be registered with ART using the function ART_callback_register().
