rendering images on a view

[arunarao]

Hello all,

The data held in a dataset can be rendered using a datapath attribute.
In a similar way if i want to render a set of images on a view within my application, can i use a dataset for this. If so how, If not is there any other way to do this.

Thanks,

Have you tried something like:



<dataset name="images">
<image>test1.jpg</image>
<image>test2.jpg</image>
<image>test3.jpg</image>
</dataset>

<view datapath="images:/image" resource="$path{'text()'}" />

I tried this way, but images are not displaying.
I have put the images in a folder named images and have put this and the lzx application under my-apps folder. I tried changing many things, but not working

Any solution plz help.. Thanks

IIRC, the values for the image must be relative to the LZX you're running OR must be a fully qualified URL just like you'd type in a browser address bar.

<dataset name="images">
<image>images/test1.jpg</image>
<image>images/test2.jpg</image>
<image>images/test3.jpg</image>
</dataset>

<view datapath="images:/image" resource="$path{'text()'}" />



You may want to post some source code so we can better help you.

FYI, I have seen Antun post that it is a bad idea to dynamically set the resource attribute to external media. Instead, overwrite the applyData method and use the setSource function. I believe resource is designed for internally compiled resources using <resource>. I could be wrong, so take this for what its worth to you.


<dataset name="images">
<image>images/test1.jpg</image>
<image>images/test2.jpg</image>
<image>images/test3.jpg</image>
</dataset>

<view datapath="images:/image">
<method name="applyData">
this.setSource(this.data);
</method>
</view>
