hdr
NMHDR structure that contains information on this notification message.
dwFlags
Either zero or LVGIT_UNFOLDED. See Remarks.
pszText
Address of a string buffer that receives any additional text information. If dwFlags is zero, this member will contain the existing item text. In this case, you should append any additional text onto the end of this string. The size of this buffer is specified by the cchTextMax structure.
cchTextMax
Size, in characters, of the buffer pointed to by pszText. Although you should never assume that this buffer will be of any particular size, the INFOTIPSIZE value can be used for design purposes.
iItem
Zero-based index of the item to which this structure refers.
iSubItem
One-based index of the subitem to which this structure refers. If this member is zero, the structure is referring to the item and not a subitem. This member is not currently used and will always be zero.
lParam
Application-defined value associated with the item. This member is not currently used and will always be zero.
备注
当当前显示的文本被截断时,该项目被折叠.如果LVGIT_UNFOLDED返回在dwFlags,已显示该项的全文,所以不需要显示在工具提示.
