CB_GETITEMHEIGHT

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.
