Using Resource to provide background attribute to td-tag?

2007-09-25 Thread wfaler 

Hi,
I want to use a ResourceReference (or something comparable) to set the
background-attribute of a td-cell with an image on my classpath.
How do I achieve this?
It is quite straightforward for images, but it gets trickier with
background-images to other html elements..

hi,
i'd say either:
myTd.add(new AttributeModifier(style, true, background-image:url( +
RequestCycle.urlFor(myImage) + );));
// use an AttributeAppender if you want to preserve an existing style
attribute

or override onComponentTag of myTd and put it in the tag like:
tag.put(style, background-image:url( + RequestCycle.urlFor(myImage) +
););

there maybe even other ways though (like interpolating a css file with the
url and rendering it in the head)

hth,

If you object to style attributes on your HTML tags, then you can do 
this by writing stuff out to the head of your page.


private static final ResourceReference IMAGE = /* ... */;
...
final Component component = /* ... */;
page.add(new AbstractBehavior() {
public void renderHead(IHeaderResponse response) {
String url = urlFor(IMAGE);

String foo = style\n;
foo += # + component.getMarkupId() +  {\n;
foo += background-image: url( + url )\n;;
foo += }\n;
foo += /style;
response.renderString(foo);
}
});

Should work. ;-)

Regards,

Al

apparently, the words in parenthesis are sometimes more important than the
rest, so yes: keep it simple...
