TVM_GETITEM message

  • Artikkel

Retrieves some or all of a tree-view item's attributes. You can send this message explicitly or by using the TreeView_GetItem macro.

Parameters

wParam

Must be zero.

lParam

Pointer to a TVITEM structure that specifies the information to retrieve and receives information about the item. With version 4.71 and later, you can use a TVITEMEX structure instead.

Return value

Returns TRUE if successful, or FALSE otherwise.

Remarks

When the message is sent, the hItem member of the TVITEM or TVITEMEX structure identifies the item to retrieve information about, and the mask member specifies the attributes to retrieve.

If the TVIF_TEXT flag is set in the mask member of the TVITEM or TVITEMEX structure, the pszText member must point to a valid buffer and the cchTextMax member must be set to the number of characters in that buffer.
