Using a CFF embedded font with a Halo DataGrid control in Flex 4

By Peter deHaan On August 21, 2009 · 3 Comments

The following example shows how you can use a CFF embedded font with a Halo DataGrid container by setting the itemRenderer property or defaultDataGridItemRenderer style to the mx.controls.dataGridClasses.TLFDataGridItemRenderer class.

Full code after the jump.

The following example(s) require Flash Player 10 and the Adobe Flex 4 SDK. To download the Adobe Flash Builder 4 trial, see http://www.adobe.com/products/flex/. To download the latest nightly build of the Flex 4 SDK, see http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4.
For more information on getting started with Flex 4 and Flash Builder 4, see the official Adobe Flex Team blog.

</s:Application>

You can set the defaultDataGridItemRenderer style in MXML, as seen in the following example:

            fontFamily: ArialCFF;
            embedAsCFF: true;
        }
    </fx:Style>
 
    <s:VGroup horizontalCenter="0" verticalCenter="0">
        <mx:DataGrid id="dataGrid"
                defaultDataGridItemRenderer="mx.controls.dataGridClasses.TLFDataGridItemRenderer"
                fontFamily="ArialCFF">
            <mx:columns>
                <mx:DataGridColumn dataField="c1" />

            <mx:dataProvider>
                <mx:ArrayList>
                    <fx:Object c1="1. One" c2="1. Two" />
                    <fx:Object c1="2. One" c2="2. Two" />
                    <fx:Object c1="3. One" c2="3. Two" />
                    <fx:Object c1="4. One" c2="4. Two" />
                    <fx:Object c1="5. One" c2="5. Two" />
                    <fx:Object c1="6. One" c2="6. Two" />
                    <fx:Object c1="7. One" c2="7. Two" />
                    <fx:Object c1="8. One" c2="8. Two" />
                    <fx:Object c1="9. One" c2="9. Two" />
                </mx:ArrayList>
            </mx:dataProvider>
        </mx:DataGrid>
        <s:SimpleText text="Spark SimpleText with embedded font" fontFamily="ArialCFF" />
    </s:VGroup>
 
</s:Application>

Or, you also set the defaultDataGridItemRenderer style globally in an external .CSS file or <Style/> block, as seen in the following example:

        }
 
        mx|DataGrid {

            fontFamily: ArialCFF;
        }
 
        s|SimpleText {

                    <fx:Object c1="2. One" c2="2. Two" />

                    <fx:Object c1="5. One" c2="5. Two" />
                    <fx:Object c1="6. One" c2="6. Two" />
                    <fx:Object c1="7. One" c2="7. Two" />
                    <fx:Object c1="8. One" c2="8. Two" />
                    <fx:Object c1="9. One" c2="9. Two" />
                </mx:ArrayList>
            </mx:dataProvider>
        </mx:DataGrid>
        <s:SimpleText text="Spark SimpleText with embedded font" />
    </s:VGroup>
 
</s:Application>

Due to popular demand, here is the “same” example in a more ActionScript friendly format:

This entry is based on a beta version of the Flex 4 SDK and therefore is very likely to change as development of the Flex SDK continues. The API can (and will) change causing examples to possibly not compile in newer versions of the Flex 4 SDK.

    This example is out of date. In the final release of Flex 4, TLFDataGridItemRenderer was renamed to FTEDataGridItemRenderer (FTE=Flash Text Engine). For a lot more details on using CFF fonts in Halo components, see this page http://opensource.adobe.com/wiki/display/flexsdk/FTE+and+TLF+text+in+MX+components
