[Laszlo-dev] Setting an resource to value of datapath

[Henry Minsky]

In the demos/amazon app, there is an example of this, a view which shows
an image of a CD album cover, from an Amazon search. It sets its datapath
to the desired xpath, and then constrains the "source" attribute to the data
value.

The line

<attribute name="source" value="${this.data}"/>

does that.



<view name="cover" datapath="ImageUrlSmall/text()" y="7" width="50"
height="50" clip="true"
onmouseover="dragsmall.display(this, this.datapath.xpathQuery('text()'))"
onmouseout="dragsmall.hide()"
onmousedown="dragsmall.start()"
onmouseup="dragsmall.stop(); this.itemDropped(parent.datapath);"
ondblclick="this.parent.getInfo()">
<attribute name="source" value="${this.data}"/>
<method name="itemDropped" args="dpath">
if (dragsmall.droppedInView(cart.parent)) {
cart.addItem(dpath);
} else if (dragsmall.droppedInView(wish.parent)) {
wish.addItem(dpath);
}
</method>
</view>
