Re: [Laszlo-user] how to cache image from dataset?

[P T Withington]

Have you tried using a resources?  I believe you can parameterize a  
resource.  Probably the most natural thing to do is make a resource  
with several frames that represent the states and then display the  
appropriate frame.

In a SOLO app, I have a view that I'm trying to do a rollover

be able to change the graphics in the future, so I load the urls  
via an
xml file. Anyway, the problem is that the view flickers when  
updating the
graphic. I've tracked this down to an HTTP request to fetch the  
image. Is
there any way to cache the rollover images, while still loading them
dynamically?



Code:



<image name="pic" datapath="[EMAIL PROTECTED]'services']"
    align="center" valign="middle"
clickable="true" visible="true"
clip="false"

    src="$path{'@image'}">

    <attribute name="normal"
value="$path{'@image'}" />

    <attribute name="active"
value="$path{'@activeimage'}" />

    <handler name="onmouseover" >

        this.setAttribute('src',
this.active);

    </handler>

    <handler name="onmouseout" >

        this.setAttribute('src',
this.normal);

    </handler>

</image>
