best way to accommodate dynamic properties
I'm interested in having pulling the width and height for an img from a database, but I'm not sure what the best way is to create a component and corresponding HTML mapping.
Please send an example or link to previous response if possible. I've searched the users list archives but didn't find what I was looking for.
Thanks.

class myimage extends image {
oncomponenttag(tag) {
Integer width=getImageWidth();
Integer height=getImageHeight();
if (width!=null) tag.put("width", width);
if (height!=null) tag.put("height", height);
}}

I think you can't do this without markup. Put in DB binary data, width
and height and pul it out then and with this data modify markup. If
image doesn't have exif data you don't know dimensions (I think...)

RE: best way to accommodate dynamic properties
Posted by Daniel Watrous <Da...@bodybuilding.com>.
I'm still trying to figure this out. I would like to be able to do something like the following:
HTML:
<img wicket:id="testimage">
JAVA:
public class ImageTestPage extends WebPage{
public ImageTestPage() {
Image myImg = new Image("testimage");
myImg.setUrlForImageSrc("http://path/to/image.gif");
myImg.setWidth(200);
myImg.setHeight(100);
add(myImg);
}
}
Obviously the Image class doesn't work that way... Can someone tell me how I would accomplish this so that I can define the image, height and width independent from the markup?
Daniel
