HEADER_PrepareCallbackItems()

static BOOL HEADER_PrepareCallbackItems ( const HEADER_INFO *  infoPtr, INT  iItem, INT  reqMask  )

static

Prepare callback items depends on NMHDDISPINFOW having same structure as NMHDDISPINFOA (so we handle the two cases only doing a specific cast for pszText). Checks if any of the required fields is a callback. If this is the case sends a NMHDISPINFO notify to retrieve these items. The items are stored in the HEADER_ITEM pszText and iImage fields. They should be freed with HEADER_FreeCallbackItems.

Parameters

hwnd	: hwnd header container handler
iItem	: the header item id
reqMask	: required fields. If any of them is callback this function will fetch it

Returns

TRUE on success, else FALSE
