Recently I wanted to set the maxHeight of a component to a percentage. Sadly enough this isn't supported in Flex. There's however a very simple workaround that seems to work all the time: set the maxHeight or maxWidth in the resize event of its container:
<mx:Canvas
id="cnvsComponent"
resize="childComponent.maxHeight = cnvsComponent.height"
width="100%" height="100%">
<mx:Tree id="childComponent" />
</mx:Canvas>
skip to main |
skip to sidebar
Sorry - I'm addicted. But I shouldn't be ashamed: I'm addicted to Adobe Flex - the solution that we should have had 10 years ago. If that would have been the case the internet would look completely different today. But don't worry: in 10 years from now it WILL look completely different :)

I wonder if you could also use in the script tags:
containerID.percentHeight = 100;
containerID.maxHeight = containerID.percentHeight;
Since you can say percentHeight in script it might be worth trying. Then you can subtract the percentage value if you don't want the full 100% of the container for max or min or whatever. Keep up the good work mang.
I see how this works, but I a very similar problem with a quirk. I have 2 chart legends which I want to layout (using FlowLayout) - but to allow them (the legends) to use their measured sizes. The FlowContainer (parent) to use a percentSize of the panel and for its sizing to not be dictated by the children (I want the scrollbars to appear for the user to use them). Its a bit of a catch 22 - so Im stuck ;)
Regards.
