Interfacepublic interface IGridItemRenderer extends IDataRenderer , IVisualElement , ILayoutElement , ILayoutDirectionElement , IEventDispatcher
Implementors DefaultGridItemRenderer, GridItemRenderer, UITextFieldGridItemRenderer

Language Version: ActionScript 3.0
Product Version: Flex 4.5
Runtime Versions: Flash Player 10, AIR 2.5

The IGridItemRenderer interface must be implemented by DataGrid item renderers. The DataGrid uses this API to provide the item renderer with the information needed to render one grid or header cell.

All of the renderer's properties are set during the execution of its parent's updateDisplayList() method. After the properties have been set, the item renderer's prepare() method is called. An IGridItemRenderer implementation should override the prepare() method to make any final adjustments to its properties or any aspect of its visual elements. Typically, the prepare() is used to configure the renderer's visual elements based on the data property.

When an item renderer is no longer needed, either because it's going to be added to an internal reusable renderer "free" list, or because it's never going to be used again, the IGridItemRenderer discard() method is called.

IGridItemRenderer
  columnIndex : int
[read-only] The column index for this item renderer's cell.

This property is set to true when one of two input gestures occurs within a grid cell: either the mouse button or the touch screen is pressed.
IGridItemRenderer
  dragging : Boolean
Contains true if the item renderer is being dragged, typically as part of a drag and drop operation.
IGridItemRenderer
  grid : Grid
[read-only] The Grid associated with this item renderer, typically just the value of column.grid.
IGridItemRenderer
  hovered : Boolean
Contains true if the item renderer is under the mouse and the Grid's selectionMode is GridSelectionMode.SINGLE_CELL or GridSelectionMode.MULTIPLE_CELLS, or if the mouse is within the row the item renderer belongs to and the Grid's selectionMode is GridSelectionMode.SINGLE_ROW or GridSelectionMode.MULTIPLE_ROWS.
IGridItemRenderer
  label : String
The String to display in the item renderer.
IGridItemRenderer
  rowIndex : int
The zero-based index of the row of the cell being rendered.
IGridItemRenderer

discard(willBeRecycled:Boolean):void
Called from the item renderer parent's updateDisplayList() method when it has been determined that this renderer will no longer be visible.
IGridItemRenderer

Dispatches an event into the event flow.
IEventDispatcher
 Inherited
Checks whether the EventDispatcher object has any listeners registered for a specific type of event.
IEventDispatcher
  
prepare(hasBeenRecycled:Boolean):void
Called from the item renderer parent's updateDisplayList() method after all of the renderer's properties have been set.
IGridItemRenderer
 Inherited
removeEventListener(type:String, listener:Function, useCapture:Boolean = false):void
Removes a listener from the EventDispatcher object.
IEventDispatcher
