Daniel R.: Truncating labels that use a percentage width

When an mx:Label is created, truncateToFit is true, and a percentage is specified for its width the label will show all of its content even if placed inside a fixed width container. The following example shows this scenario:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical">
<mx:HBox width="100" horizontalScrollPolicy="off">
<mx:Label text="This is a really long label" width="100%" truncateToFit="true"/>
<mx:Button label="X"/>
</mx:HBox>
</mx:Application>

The result is which is not what I had hoped would happen.

The fix is to specify a minWidth for the label. If another HBox is added as shown below the label behaves correctly.

<mx:HBox width="100" horizontalScrollPolicy="off">
<mx:Label text="This is a really long label" width="100%" minWidth="0" truncateToFit="true"/>
<mx:Button label="X"/>
</mx:HBox>

The new result is which is just what I wanted.
