Changing the truncation indicator on a Spark Label control in Flex 4

By Peter deHaan On October 15, 2009 · 1 Comment

The following example shows how you can change the truncation indicator (“…”) on a Spark Label control in Flex 4 by setting the static TextBase.truncationIndicatorResource property in the mx_internal namespace.

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.

Since this example uses the mx_internal namespace, you can't always depend on this behavior to work in future versions of the Flex SDK. Use at your own risk.

View source is enabled in the following example.

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.
