placing the controls/components using the Percentage facility

[Ravi Kiran Va]

Hi ,

This question is about placing the controls/components using the Percentage facility .

From Adobe it is mentioned that :

"You specify the component size as a percentage of its container size. To do this, you specify the percentHeight and percentWidth properties, or, in an MXML tag, set the height and width properties to percentage values such as 100%. "

Can anybody tell me how is this approach different from the normal height and width of a Component ?? and

How can we deteremine the percenategheight and percentagewidth for a component . For example in below example the author has taken as shown :

<mx:HBox id="hBox1" xmlns:mx="http://www.adobe.com/2006/mxml"
height="30%" width="90%"/>

My question is how can we know that heights value and widths value should be 30 and 90 respectively ??

Please let me know this , Thanks in advance .
