HDM_SETITEM
The HDM_SETITEM message sets the attributes of the specified item in a header
control. You can send this message explicitly or by using the Header_SetItem macro.
HDM_SETITEM
wParam = (WPARAM) (int) index;
lParam = (LPARAM) (const HD_ITEM FAR*) phdi;
Parameters
index
Index of the item whose attributes are to be changed.
phdi
Pointer to an HD_ITEM structure. When the message is sent, the mask member indicates the attributes to set. The other members specify new
attributes.
Return Values
If the operation succeeds, the return value is TRUE.
If the operation fails, the return value is FALSE.
Remarks
The HDN_ITEMCHANGING notification message is sent to the parent window before
the item attributes are changed. The parent window can return FALSE to prevent
the changes, and in that case, HDM_SETITEM returns FALSE. If the parent window
returns TRUE, the changes are made and the parent window receives the
HDN_ITEMCHANGED notification message.
