$ character in calendar app

[Peter_Chea]

Hi Antun, I keep seeing the $ character in the calendar demo. What does it do?
<attribute name="eventwidth"
value="${details.bgrect.width - ( this.opened ? 38 : 0 )}"/>

This is a new way (in v1) of specifying attributes.


<attribute name="eventwidth"
value="${details.bgrect.width - ( this.opened ? 38 : 0 )}"/>


... is like the old:


<attribute name="eventwidth"
constraint="details.bgrect.width - ( this.opened ? 38 : 0 )"/>


Essentially it's a constraint. We're trying to make the <attribute> tag a little more user friendly.
