Item renderers are associated with each column of a grid.
Set the item renderer for a column by using
the GridColumn.itemRenderer property.
By default, an item renderer does not clip to the boundaries of the cell.
If your renderer extends past the bounds of the cell, you can set
clipAndEnableScrolling to true to clip the renderer to the bounds
of the cell.
Transitions in DataGrid item renderers aren't supported. The GridItemRenderer class
has disabled its transitions property so setting it will have no effect.
Efficiency Considerations
DataGrid scrolling and startup performance are directly linked to item renderer complexity and the number of item renderers that are visible within the DataGrid's scroller. Custom GridItemRenderer instances are used and reused repeatedly so it's important to define them as simply and efficiently as possible.
If an item renderer's responsibility is limited to displaying
one or more lines of text, then developers should seriously
consider using the DefaultItemRenderer class which does so very
economically (an application that's only going to be deployed on
Windows one can gain some additional performance by using the
UITextFieldGridItemRenderer class instead). The most efficient
way to use GridItemRenderer to display the GridColumn's dataField
as text is to identify the GridItemRenderer's text displaying
element with id="labelDisplay". The labelDisplay
component must be a TextBase subclass like
Label or RichText. You might take this
approach, instead of just using DefaultGridItemRenderer, if your
item renderer included some additional elements that did not
depend on the item renderer's data, like borders or other graphic
elements.
An item renderer that contains more than one visual element
whose properties depend on the item renderer's data can use data
binding to define the values of those properties. This approach
yields MXML code that's straightforward to read and maintain and
its performance may be adequate if the number of visible item
renderers is limited (see the DataGrid requestedRowCount
and requestedColumnCount properties). The most efficient
way to configure this kind of item renderer is to override its
prepare() method and do the work there. The
renderer's prepare() method is called each time the
renderer is redisplayed and so it's important that it's coded
efficiently. If your item renderer is stateful, for example if it
caches internal values, you can clear its state in its
discard() method. The discard() method
is called each time the renderer is moved to the DataGrid's
internal free list, where it's available for reuse.
GridItemRenderers should be as simple as possible. To gain the
best possible performance, minimize the number of components, and
the depth of the hierarchy. If it's practical, use explicit
positions and sizes rather than constraints to define the layout.
DataGrid's with variableRowHeight="false" (the
default) tend to perform better, likewise for
showDataTips="false" (the default) and
clipAndEnableScrolling="false" (the default).
Examples of the various GridItemRenderer configurations described here are available in the examples section.

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.
The down property is reset to false when
the mouse button goes up, the user lifts off
the touch screen, or the mouse/touch is dragged out of the grid cell.
Unlike a List item renderer, grid item renderers do not have exclusive responsibility for displaying the down indicator. The Grid itself renders the down indicator for the selected row or cell. The item renderer can also change its visual properties to emphasize that it's being pressed.

| 제품 버전: | Flex 4.5 |
| 런타임 버전: | Flash Player 10, AIR 2.5 |
Called from the item renderer parent's updateDisplayList() method
when it has been determined that this renderer will no longer be visible.
If the willBeRecycled parameter is true,
then the owner adds this renderer to its internal free list for reuse.
Implementations can use this method to clear any renderer properties that are no longer needed.
This method is not intended to be called directly. It is called by the DataGrid implementation.
매개 변수
willBeRecycled:Boolean — true if this renderer is going to be added
to the owner's internal free list for reuse.

getCurrentRendererState | () | 메서드 |
protected function getCurrentRendererState():String| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4.5 |
| 런타임 버전: | Flash Player 10, AIR 2.5 |
Returns the name of the state to be applied to the renderer. For example, a basic item renderer returns the String "normal", "hovered", or "selected" to specify the renderer's state. If dealing with touch interactions (or mouse interactions where selection is ignored), "down" and "downAndSelected" can also be returned.
A subclass of GridItemRenderer must override this method to return a value if the behavior desired differs from the default behavior.
In Flex 4.0, the 3 main states were "normal", "hovered", and "selected". In Flex 4.5, "down" and "downAndSelected" have been added.
The full set of states supported (in order of precedence) are:
- dragging
- downAndSelected
- selectedAndShowsCaret
- hoveredAndShowsCaret
- normalAndShowsCaret
- down
- selected
- hovered
- normal
String — A String specifying the name of the state to apply to the renderer.

prepare | () | 메서드 |
public function prepare(hasBeenRecycled:Boolean):void| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4.5 |
| 런타임 버전: | Flash Player 10, AIR 2.5 |
Called from the item renderer parent's updateDisplayList() method
after all of the renderer's properties have been set.
The hasBeenRecycled parameter is false
if this renderer has not been used before, meaning it was not recycled.
This method is called when a renderer is about to become visible
and each time it's redisplayed because of a change in a renderer
property, or because a redisplay was explicitly requested.
This method can be used to configure all of a renderer's visual
elements and properties.
Using this method can be more efficient than binding data
properties to visual element properties.
Note: Because the prepare() method is called frequently,
make sure that it is coded efficiently.
The prepare() method may be called many times
before the discard() method is called.
This method is not intended to be called directly. It is called by the DataGrid implementation.
매개 변수
hasBeenRecycled:Boolean — true if this renderer is being reused.

Demonstate how to control text wrapping in DataGrid GridItemRenderer item renderer.
This DataGrid example demonstrates how to control text wrapping with a simple custom item renderer
based on GridItemRenderer. All cells in this example display the same lengthy string which does
not contain newlines. Note that the Flex text components unconditionally render newline characters
that appear in the text.
The "Label Renderer" column's renderer is a custom GridItemRenderer that displays its text with
an s:Label component. We use the Label's maxDisplayedLines property to control line breaking
and to include "..." truncation when the single line of text doesn't fit.
Note also: this example's column widths and row heights are defined by the DataGrid's typicalItem.
The typical item uses explicit newlines to create a string that occupies three lines and a
reasonable column width.

GridItemRendererCustomBindingExample.mxml
<?xml version="1.0" encoding="utf-8"?>
<!--
Examples of custom GridItemRenderers that use data binding to configure visual properties.
The application's control bar slider can be used to change the the dataProvider items.
The GridItemRenderer class is a Group that implements
IGridItemRenderer and can be used as the top level "container" for a
custom item renderer. Its data property is the dataProvider item for
the row the item renderer appears on and its components can configure
themselves by binding to the data property, or by overriding the
renderer's prepare() method and configuring themselves imperatively
with ActionScript code. All of the item renderers in this example
use binding, which makes the code a little easier to read and modify.
It's also less efficient than using a prepare() method override. The
performance difference is most noticeable when the DataGrid is configured
so that a large number of item renderers are visible.
DataGrid item renderers are always sized to exactly fit the cell that
they're rendering: their size matches the width of their column and the height of their row.
The DataGrid enables interactive column resizing by default, so all of
the item renderers need to defend against the possibility that their
width will become arbitrarily small. The first column's item renderer
just contains a Label. By specifying maxDisplayedLines="1" we ensure
that the Label will truncate its text to fit the width it's given.
The other columns' item renderers specify
clipAndEnableScrolling="true" which just means that their fixed size
contents will always be clipped to the bounds of the GridItemRenderer.
This property -enables- scrolling, which means that one could actually
scroll the contents of the item renderers when their width gets small,
by setting the renderer's horizontalScrollPosition property. We
do not do as much here.
The "Name" column's item renderer demonstrates a special case: if the
renderer contains a text component with id="labelDisplay", GridItemRenderer
automatically sets the labelDisplay's text property to the value
of data[column.dataField] per the GridItemRenderer label property. The
first colunm also demonstrates using the styleName property to configure
the Label's left, right, top, and fontSize styles.
The "Statistics" column's item renderer demonstrates how binding can be used to
configure the geometry of graphic elememnts. The data items' min, max, and
value properties have been normalized to the range [0 100] to keep the bindings simple.
The "Value" column's item renderer allows one to change data item's value
property with a Slider.
The "Call" column's item renderer demonstrates a slightly more complicated component
layout and it also demonstates how the data item's value can be both displayed
and edited.
