CB_GETITEMHEIGHT message
Determines the height of list items or the selection field in a combo box.
Parameters
-
wParam
-
The combo box component whose height is to be retrieved. This parameter must be -1 to retrieve the height of the selection field. It must be zero to retrieve the height of list items, unless the combo box has the CBS_OWNERDRAWVARIABLE style. In that case, the wParam parameter is the zero-based index of a specific list item.
-
lParam
-
This parameter is not used.
Return value
The return value is the height, in pixels, of the list items in a combo box. If the combo box has the CBS_OWNERDRAWVARIABLE style, it is the height of the item specified by the wParam parameter. If wParam is -1, the return value is the height of the edit control (or static-text) portion of the combo box. If an error occurs, the return value is CB_ERR.
