Re: "after render" using a behavior vs. override in the component
use a behavior that adds an onDocumentLoad/Ready script to the browser

Re: "after render" using a behavior vs. override in the component
ok. thank, I'll try it (though I have never written JavaScript till a few
days ago...)
BTW, why is the difference between the overriding method and the behavior
method?

Re: "after render" using a behavior vs. override in the component
you can also do it on component
public void renderHead(final HtmlHeaderContainer container)
or let the component implement IHeaderContributor
i guess that renderHead(final HtmlHeaderContainer container) shouldnt be
public but more protected or final..

Re: "after render" using a behavior vs. override in the component
thanks,
that's exactly what I did.
I add to my component (button) an AbstarctBehavior, which is an
IHeaderContributor.
I even override renderHead:
@Override
public void renderHead(IHeaderResponse response) {
response.renderCSSReference("/eurekify/style/button/EurekifyButton.css");
response.renderJavascriptReference("/eurekify/style/button/EurekifyButton.js");
//response.renderJavascriptReference(new
JavascriptResourceReference(
//EurekifyButtonBehavior.class, "resizeScript.js"));
}
The script I am adding to each button comes from a utility class:
static String getResizeScript(String markupId) {
StringBuilder strBuilder = new StringBuilder();
strBuilder.append("");
strBuilder.append("document.getElementById('btnObj_");
strBuilder.append(markupId);
strBuilder.append("').style.width = calcBtnSize('");
strBuilder.append(markupId).append("')");
strBuilder.append("");
return strBuilder.toString();
}
This is the script that I mentioned in my first question.
Again:
If I call this script in the Button class, in the onAfterRender() method, it
is added to the end of the output HTML.
If I call this in the behavior, in the onRendered(Component component), it
is added just after the .
I did something like this in the onload script:
window.onload = function(id) {
document.getElementById('btnObj_'+id).style.width = function(id)
{calcBtnSize(id)};
}
firebug says that it can't find document.getElementById('btnObj_'+id) ...

Re: "after render" using a behavior vs. override in the component
Isn't this is what I did?
Anyway, here's an example of what I get.
First: the Java code:
public final class TestButtonPage extends WebPage {
public TestButtonPage() {
add(new ExtendingButton("extendingButton"));
Button other = new Button("behavioralButton");
other.add(new MyBehavior());
add(other);
}
class ExtendingButton extends Button {
private static final long serialVersionUID = 1L;
public ExtendingButton(String id) {
super(id);
}
@Override
protected void onAfterRender() {
getResponse().write("ExtendingButton.onAfterRender()");
super.onAfterRender();
}
}
class MyBehavior extends AbstractBehavior {
private static final long serialVersionUID = 1L;
@Override
public void onRendered(Component component) {
component.getResponse().write("AbstractBehavior.onRendered(...)");
}
}
}
This is the markup:
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
http://www.w3.org/1999/xhtml";
xmlns:wicket="http://wicket.apache.org/"; xml:lang="en" lang="en">
Button Test
Extending Button
Behavioral Button
This is just before the html closing tag
And this is the output (taken from view source in my FF browser):
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
http://www.w3.org/1999/xhtml";
xmlns:wicket="http://wicket.apache.org/"; xml:lang="en" lang="en">
Button Test
Extending Button
Behavioral
ButtonAbstractBehavior.onRendered(...)
This is just before the html closing tag
ExtendingButton.onAfterRender()
As you can see, the behavior put the tag just after the button, but
the "extendingButton" put the tag after the closing tag of the html.
Is this the correct behavior?
thanks

Re: "after render" using a behavior vs. override in the component
No the after render of a component is called after the page render to
clean up stuff.
Just as onBeforeRender is called before the page is starting to render

Re: "after render" using a behavior vs. override in the component
ok.
But, looking at the Javadoc, this is what I see:
In AbstractBehavior:
/**
* Called when a component that has this behavior coupled was rendered.
*
* @param component
*the component that has this behavior coupled
*/
public void onRendered(Component component)
{
}
And in Component:
/**
* Called just after a component is rendered.
*/
protected void onAfterRender()
{
setFlag(FLAG_AFTER_RENDERING, false);
}
It looks to me that according to the API Javadoc the output should be same.
But it isn't.
Am I misunderstanding something or there's a minor bug?

Re: "after render" using a behavior vs. override in the component
No no bug just java doc isnt clear enough i guess, but it is not
really wrong.. What is after render? Both are true, both are called
after the component is rendered only one a bit later then the other. I
guess the javadoc of the component should state that this is after the
page is rendered
