Setting the horizontal alignment on a FxList control in Flex Gumbo

The following example shows how you can set the horizontal alignment on a Flex Gumbo FxList control with a vertical layout by setting the horizontalAlign property on the VerticalLayout object to one of the static constants in the mx.layout.HorizontalAlign class.

Full code after the jump.

To use the following code, you must have Flash Player 10 and a Flex Gumbo SDK installed in your Flex Builder 3. For more information on downloading and installing the Gumbo SDK into Flex Builder 3, see “Using the beta Gumbo SDK in Flex Builder 3″.

This entry is based on a beta version of the Flex Gumbo 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 Gumbo SDK.
