CB_SETITEMHEIGHT
An
application sends a CB_SETITEMHEIGHT message to set the height of list items or
the selection field in a combo box.
CB_SETITEMHEIGHT
wParam = (WPARAM) index; // item index
lParam = (LPARAM) (int) height; // item height
Parameters
index
Value of 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 index parameter is the zero-based index of a specific list item.
height
Value of lParam.
Specifies the height, in pixels, of the combo box component identified by index.
Return Values
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.
