T5: Newbie
I'm a complete newbie to T5. I need to develop my own component to go
into a page. Could someone please direct me to an example on the web.
The component is very simple - it will just inject HTML from an external
source.
Thanks
Alan Chaney

Writing components in T5 is very simple. A good source of examples is
http://jumpstart.doublenegative.com.au:8080/jumpstart/.
In your case, you need to pull HTML from an external source. For this, I
recommend Apache HttpClient. Once you have the needed HTML in a String,
you'll need to write it to the output. This is done using a MarkupWriter.
This is a component I use in my projects. Look at it to see how you can
use a MarkupWriter. You'll need to use MarkupWriter.writeRaw() instead of
write(), as the latter encodes the strings (< into <, etc).
public class Message {
/**
* Message to be shown.
*/
@Parameter(required = true)
private String message;
@BeforeRenderTemplate
public boolean render(MarkupWriter writer) {
if (message != null && message.trim().length() > 0) {
writer.element("div", "class", "t-crud-message");
writer.element("p");
writer.write(message);
writer.end(); // p
writer.end(); // div
}
return false;
}
}
