ondatacomplete?

[whisperstorm]

is there a way to know when the data for some dataset has completed "downloading"? I want to for instance hide a resource until it's data has been downloaded and it's properties updated - say an image fetched from the net. Like say an ondatacomplete event?

I don't think there's an ondatacomplete event per se, but usually I set up a datapointer to some spot in the dataset, and use that datapointer's ondata event, to achieve the same effect:


<canvas debug="true">
<dataset name="foo" src="foo.xml" type="http" autorequest="false" />


<datapointer xpath="foo:/">
<method event="ondata">
debug.write( "Data of foo has completed" );
</method>
</datapointer>


<simplelayout axis="y" spacing="10" />

<button>Make Request
<method event="onclick">
foo.doRequest();
</method>
</button>

<text datapath="foo:/foo/@val" width="100" />

</canvas>
