Thanks Nino,
The model is just a quick hack to show where the imageresource is
coming from, i.e. it's dynamic.
ahh...
The ClientSideImageMap and the older ImageMap don't give an x and y of
the click and I don't fancy creating a <map/> for every pixel in the
image.
I surely understand...
The ImageButton does return where the user clicked on the image as
part of the form submit. I was hoping that the x and y could be
mapped to a model somehow.
It should be possible I think..
How I managed to get the coords is like this
Form<Object> form = new Form<Object>("form") {
@Override
protected void onSubmit() {
info("x = " + getRequest().getParameter("picture.x"));
info("y = " + getRequest().getParameter("picture.y"));
}
};
It would be nice to attach these values to a property, can you see a
way of doing that?
It reminds me of something. IF you combine this technique:
https://wicket-stuff.svn.sourceforge.net/svnroot/wicket-stuff/trunk/wicket-contrib-openlayers/src/main/java/org/wicketstuff/openlayers/event/EventListenerBehavior.java
im thinking of this method : protected abstract void
onEvent(AjaxRequestTarget target);
So combine above with how an ordinary link or button works you should be
able to pass on parameters either as a model or as nice parameter eg :
protected abstract void onClick(Double x, Double y);
If you have questions just ask..

Otherwise it should be ImageMap already there..

Hi Tim
You should get a grasp on models. But isnt it an imagearea (cant
remember the exact name) or something you want? Image button is just
a button which has a image...

Hi,
I'm trying to retrieve the x and y coords from a user click on an
ImageButton. Can anyone tell me how to get these parameters in an
onSubmit method?
Currently I'm doing
final IModel<Picture> picture = new
AbstractReadOnlyModel<Picture>() {
@Override
public Picture getObject() {
return pictureService.findRandom();
}
};
Form<Object> form = new Form<Object>("form") {
@Override
protected void onSubmit() {
// picture.x and picture.y
parameters, where are they?
}
};
form.add(new ImageButton("picture", new
ImageResource(defaults
.getPicturesLocation(), picture)));
add(form);
but cannot find any way of retrieving the page parameters in the
onSubmit() - getPageParameters() returns null.
I'm using 1.4-rc1.
Thanks for any help,
Tim
