CB_SETITEMHEIGHT

wParam = (WPARAM) index; /* item index */

lParam = (LPARAM) (int) height; /* item height */

An application sends a CB_SETITEMHEIGHT message to set the height of list items in a combo box or the height of the edit-control (or static-text) portion of a combo box.

Parameters

index

Value of wParam. Specifies whether the height of list items or the height of the edit-control (or static-text) portion of the combo box is set.

If the combo box has the CBS_OWNERDRAWVARIABLE style, the index parameter specifies the zero-based index of the list item whose height is to be set; otherwise, index must be zero and the height of all list items will be set.

If index is -1, the height of the edit-control or static-text portion of the combo box is to be set.

height

Value of the low-order word of lParam. Specifies the height, in pixels, of the combo box component identified by index.

Return Value

The return value is CB_ERR if the index or height is invalid.

Comments

The height of the edit control (or static text) portion of the combo box is set independently of the height of the list items. An application must ensure that the height of the edit control (or static text) portion isn't smaller than the height of a particular listbox item.
