Why Stack Overflow recommends it
Stack Overflow users link it when explaining how to monkey patch Flex SDK classes to change behavior that subclassing cannot reach.

What it is
A short clip from a 360Flex conference talk by Doug McCune about monkey patching the Flex framework source. It explains the technique of overriding SDK classes by placing your own copy in the same package. Presented informally as a developer talk excerpt from 2007.

You're going to need to monkey-patch the class for this. LinkBar is essentially a horizontal box who automatically adds spacer objects between its children. Check out the updateDisplayList method - note that the size of the separators is set with this bit of code: if (isVertical()) { ... separator.setActualSize(separatorWidth, verticalGap); ... } else { ... separator.setActualSize(horizontalGap, separatorHeight); ... } You'll need to change this behavior somehow. My recommendation is to detect if this is the last spacer in the object (by comparing the loop iterator "i" to the total number of objects "n" in the child list) and, if it is, set it's width to either 100% or an explicitly calculat

Subclass is main solution. Next works only with mx components (flex sdk 3). Most components have data : Object property that you can freely use to store data. Monkey patching [this video] sometimes is the only way to go. It allows you to add custom properties to flex sdk classes. I don't think you should use it in your case. But I used it to change core logic that is locked by private keyword in flex sdk. Hope that helps.

What you want to do is called " Monkey Patching [this video] ." What you need to do is create your own version of the file in the same package location, and yours will be used in preference to the one from the swc.
