Setting the tooltip on the full screen button on a Spark VideoPlayer control in Flex 4

The following example shows how you can set the tooltip on the full screen button on a Spark VideoPlayer control in Flex 4 by setting the toolTip property on the fullScreenButton reference.

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.

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.
