Creating a radial gradient fill on a Rect object in Flex Gumbo

In a previous example, “Creating a linear gradient fill on an Ellipse object in Flex Gumbo”, we saw you could create a linear gradient fill on a Flex Gumbo Ellipse object by setting the fill property to a LinearGradient object.

The following example shows how you can create a radial gradient fill on a Flex Gumbo Rect object by setting the fill property to a RadialGradient object.

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.

  1. This is really cool, but example does not show a radial gradient, it shows 3 different linear gradients. Still very cool!

  2. I am trying to manipulate rect and other objects programaticaly at run time with action script. Can you please provide an example of how to add a gradient fill to a rect with action script code after the rect has already been created in mxml.

    Thanks
    Lawrence
