The following example shows how you can create a semi-transparent scroll bar thumb skin on an MX TextArea control in Flex 4 by setting the alpha property on the scroll bar thumb skin part’s fill.

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.

View source is enabled in the following example.

You can also set the verticalScrollBarStyleName style in an external .CSS file or <mx:Style /> block, as seen in the following snippet:

<mx:Style>
    List {
        verticalScrollBarStyleName: tracklessScrollBar;
    }

    .tracklessScrollBar {
        trackSkin: ClassReference(null);
    }
</mx:Style>

Or, you can set the verticalScrollBarStyleName style directly within MXML, as seen in the following snippet:

<mx:List id="list"
        dataProvider="{arr}"
        rowCount="6"
        width="100"
        verticalScrollBarStyleName="tracklessScrollBar" />
