<h3>e775. Setting the Dimensions of an Item in a JList Component</h3>
By default, the width of the list is determined by the longest item
and the height is determined by the number of visible lines multiplied
by the tallest item. This example demonstrates how to override these
values.
<pre> // Create a list
String[] items = {<font color="#0066ff"><i>"A", "B", "C", "D"</i></font>};
JList list = new JList(items);
// Set the item width
int cellWidth = <font color="#0066ff"><i>200</i></font>;
list.setFixedCellWidth(cellWidth);
// Set the item height
int cellHeight = <font color="#0066ff"><i>18</i></font>;
list.setFixedCellHeight(cellHeight);
</pre>
It is also possible to set the item dimensions using a sample value:
<pre> String protoCellValue = <font color="#0066ff"><i>"My Sample Item Value"</i></font>;
list.setPrototypeCellValue(protoCellValue);
</pre>
