Re: ImageButton picture.x and picture.y

[Tim Squires]

Thanks Nino,

The model is just a quick hack to show where the imageresource is coming 
from, i.e. it's dynamic.

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.

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.

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?

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
