DELETEITEMSTRUCT Structure

  • Article

The DELETEITEMSTRUCT structure has the following form:

typedef struct tagDELETEITEMSTRUCT { /* ditms */
    UINT CtlType;
    UINT CtlID;
    UINT itemID;
    HWND hwndItem;
    UINT itemData;
} DELETEITEMSTRUCT;

The DELETEITEMSTRUCT structure describes a deleted owner-drawn list-box or combo-box item. When an item is removed from the list box or combo box or when the list box or combo box is destroyed, Windows sends the WM_DELETEITEM message to the owner for each deleted item. The lParam parameter of the message contains a pointer to this structure.
