Flex Examples

This is a more complex version of my previous example. This time in addition to making the Alert control’s text non-selectable, we use an embedded font for the Alert title, message, buttons, as well as edit the drop shadow, remove the rounded corners, and remove the button skins.

Full code after the jump.

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.

I didn’t include the TrueType font in the source code ZIP. If you want to grab that exact font, head over to the creator’s site @ http://www.stereo-type.net/ and download “Base 02″.
