I'm looking at LPP-2037.
I'd like to provide a simple example that illustrates the different
values for
constraints in tags, something like this:
<canvas>
<view x="250" width="20" height="20" bgcolor="red" y="$once{m.y}"/>
<view x="280" width="20" height="20" bgcolor="blue"
y="$immediately{m.y}"/>
<view x="310" width="20" height="20" bgcolor="green" y="$always
{m.y}"/>
<window id="m" x="10" title="Drag me" width="160" height="20"/>
</canvas>
I don't understand the difference between "once" and "immediately",
and this
example doesn't illustrate the difference.
What's the difference, and is there a better example I can use?
Thanks,
Lou
