CB_SETITEMHEIGHT

3.1

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 list box item.

Example

This example sends a CB_SETITEMHEIGHT message to set the height of list items in a combo box:

LPARAM lrHeight;

SendDlgItemMessage(hdlg, ID_MYCOMBOBOX, CB_SETITEMHEIGHT,
    0, lrHeight);
