    "description": "This interface provides a method that dynamically created visual elements can use to configure themselves before they're displayed. It's called as needed when a factory generated visual element is created or reused.  It is not intended to be called directly.  <p>This is an optional interface for all of the factory-generated visual elements except itemRenderers: <code>caretIndicator</code>, <code>hoverIndicator</code>, <code>editorIndicator</code>, <code>selectionIndicator</code>, <code>columnSeparator</code>, <code>rowSeparator</code>, <code>alternatingRowColorsBackground</code> (see DataGrid), <code>sortIndicator</code> (see GridColumnHeaderGroup).  It's typically used to configure generated visual elements with DataGrid's style values.  For example, to use the value of the DataGrid's &quot;symbolColor&quot; style for the caret's fill color, one would define the <code>prepareGridVisualElement()</code> method like this:</p>  <p> <pre>\\n public function prepareGridVisualElement(grid:Grid, rowIndex:int, columnIndex:int):void\\n {\\n caretStroke.color = grid.dataGrid.getStyle(&quot;caretColor&quot;);\\n }\\n </pre> </p>  <p>The <code>rowIndex</code> and <code>columnIndex</code> parameters specify the the cell the visual element will occupy.  If <code>columnIndex</code> = -1 then the visual element occupies a Grid row. If <code>rowIndex</code> = -1 then the visual element occupies a Grid column.</p>  <p>There are many more examples like this in DataGridSkin.mxml.  Note that custom DataGrid skin visual elements can choose not to implement this interface if the the added flexibility isn't needed.</p>",
