CB_SETITEMHEIGHT message
An application sends a CB_SETITEMHEIGHT message to set the height of list items or the selection field in a combo box.
Parameters
-
wParam
-
Specifies the component of the combo box for which to set the height.
This parameter must be 1 to set the height of the selection field. It must be zero to set 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
-
Specifies the height, in pixels, of the combo box component identified by wParam.
Return value
If the index or height is invalid, the return value is CB_ERR.
Remarks
The selection field height in a combo box is set independently of the height of the list items. An application must ensure that the height of the selection field is not smaller than the height of a particular list item.
