This structure contains information needed to display an owner-drawn item in a list-view control.
NMHDR structure that contains information about this message.
LVITEM structure that identifies the item or subitem. The structure either contains or receives information about the item. The mask member contains a set of bit flags that specify which item attributes are relevant. It can be one or more of the following bit flags.
The iImage member specifies, or is to receive, the index of the item's icon in the image list.
The state member specifies, or is to receive, the state of the item.
The pszText member specifies the new item text or the address of a buffer that is to receive the item text.
If the structure is receiving item text, the pszText and cchTextMax members specify the address and size of a buffer. You can either copy text to the buffer or assign the address of a string to the pszText member. In the latter case, you must not change or delete the string until the corresponding item text is deleted or two additional LVN_GETDISPINFO messages have been sent.
If you are handling the LVN_GETDISPINFO message, you can set the LVIF_DI_SETITEM flag in the mask member. This tells the operating system to store the requested list item information and not ask for it again. For list-view controls with the LVS_REPORT style, this flag only applies to the first (subitem 0) column's information. The control will not store information for subitems.
