ImageMap
Are there any plans to improve the current ImageMap implementation? My problems are: 1. The rendered HTML ist no valid XHTML. 2. The constructor does not support a ResourceReference for the image 3. I can't see a way to control the tags (e.g. add style, class or alt attributes).

Re: ImageMap
The area tag is controlled by the AbstractLink that you attach to it. So, if you put an AttributeModifier on it, it'll modify the . On Wed, Aug 5, 2009 at 4:46 PM, Stefan Lindner wrote: > Ah!

ImageMap and Ajax
Hi,
I'm using an ImageMap to display an image. Whenever a user clicks on the
image, the coordinates get sent to the Server using AJAX. There, I want to
add a CircleLink to the place where the user clicked. So I'm trying to
replace the whole map using:
protected void onEvent(AjaxRequestTarget target) {
WebRequest request = (WebRequest) getRequest();
final Map parameters =
request.getParameterMap();
final int x = Integer.parseInt(parameters.get("x")[0]);
final int y = Integer.parseInt(parameters.get("y")[0]);
imageMap.addCircleLink(x, y, 10, new Link("testLink") {
@Override
public void onClick() {
// TODO Auto-generated method
stub
}
});
target.addComponent(imageMap);
PicMapPanel.this.processResult(x, y, target);
}
My problem now is that the imageMap can't be replaced. AJAX debug says
"ERROR: Component with id [[theMap2]] a was not found while trying to
perform markup update. Make sure you called
component.setOutputMarkupId(true) on the component whose markup you are
trying to update."
And yes, I'm sure I called it, but it can't be found in the markup.
Does anyone have an idea how to solve this? Maybe in a completely different
way, I wouldn't mind that ;-)
Michael

Re: ImageMap and Ajax
Well that wasn't quite my question :-), I know and use this approach, but to
draw something on an image or to add a link, I do have to use ImageMap, or
don't I?

JFreeChart with clickable imagemap
Hi Guys, I followed the instructions in the wiki "JFreeChart with clickable imagemap<https://cwiki.apache.org/WICKET/jfreechart-with-clickable-imagemap.html>" to create a chart. I have a requirement whereby the chart has to be generated dynamically based on certain inputs. I managed to create the chart image by using LoadableDetachableModel but struggling to get the imagemap updated as the chart image changes. Kindly give your valuable suggestions. -- Thanks & Regards, James
ALT tags within an ImageMap
Hi There All!
Working with Wicket for a while now, and really starting to get hooked,
great stuff!
I am working on a user interface for an application, and ran into a
(minor) thing, I hope someone can shine a light on this.
In a shortcut menu, I am using an imagemap with a couple of links in it,
and I am wondering if it is possible to create some ALT tags for mouse
over actions, one for each link The links in the Imagemap look this this
(simplified for readability):
imageMap.addPolygonLink(new int[] {123,123), new
BookmarkablePageLink("Support", SupportHomePage.class);
So I tried to create a SimpleAttributeModifier on both the PolygonLink
and BookmarkablePageLink, but unfortunately none of them worked.
Did I miss something here, or is there just no possibility?
thanks in advance!

Wicket 1.4.12 and ImageMap deprecated ?
Hello all ! Since i upgraded to Wicket 1.4.12, I noticed that the ImageMap class has been deprecated, and the Javadoc states that its going away in 1.4+ to be replaced by ClientSideImageMap. Unfortunately, the ClientSideImageMap is not present yet! I do not really care about the compilation warning, but was wondering if this is intended for 1.5 or expected in future releases of Wicket 1.4, or if maybe the Javadoc should be updated ? Thanks alot !

Re: JFreeChart with clickable imagemap
Hi James, In the constructImageMap you whill have to pass a model as well, but I'm not sure how :-( Another way would be to adapt constructImageMap to updateImageMap so that you can call it in ChartImage.createBufferedImage (or every time the model updates) BTW: For jetwick I used an html solution with div's to display bar charts. which is customizable by the designer (if any ;-)), readable by spiders etc and didn't need those imagemaps. Are you interested in this solution? I could blog about it.

Re: JFreeChart with clickable imagemap
Hi Peter, Thanks for your prompt reply. I don't know how I missed this wonderful mailing list for this long.. ;-( I have tried passing models to constructImageMap (wrapping the chart image object as a model) but somehow the map was not updated. I checked jetwick and it looks cool. ;-) Do you use JFreeChart to create those charts? I'm willing to try that option as well. Kindly blog about it! Thanks once again for taking your time to reply.

Re: JFreeChart with clickable imagemap
Guys, Finally managed to display the tooltip generated by JFreeChart in the wicket page by following these instructions<http://markmail.org/message/r36cvdt2o3c4pki6#query:wicket%20jfreechart%20tooltips+page:1+mid:xqpnjdsj2lnkoinq+state:results> . Had only an example markup been given in that post, it would have saved lots of frustrating hours I spent. :-( For anyone looking forward for showing the tooltips in a chart generated by JFreeChart, here is the markup you might need. For the java part, use this code<http://markmail.org/message/r36cvdt2o3c4pki6#query:wicket%20jfreechart%20tooltips+page:1+mid:xqpnjdsj2lnkoinq+state:results> . Your output should look something like this.. NOTE: - You must use and not - You must use the "#" symbol before the "usemap" id. - The image map related html markup is generated by the api provided by JFreeChart.

Re: ALT tags within an ImageMap
You might want to try my ClientSideImageMap class:
https://issues.apache.org/jira/browse/WICKET-1936
<https://issues.apache.org/jira/browse/WICKET-1936>It's a bit more flexible
than the existing implementation (and it'll support what you're wanting to
do). The existing client side image map just grabs the URL off the link.
It doesn't "attach" the link to the area of the map. ClientSideImageMap
takes advantage of the fact that you can attach a Link object to any markup
element.

It will stay in 1.4+ and it is already replaced with ClientSideImageMap in 1.5.

How to link ImageMap to an image?
I'm trying to use ImageMap. I've got a dynamically generated image, using RenderedDynamicImageResource to generate the image from a list of objects, each of which has its own coordinates (which works fine). Now I want an imagemap so that I can actually click on those objects. I thought this wouldn't be too hard, considering I've got that list of objects with their coordinates, and Wicket contains a convenient ImageLink class which has convenient addCircleLink() and addPolygonLink() methods. When I use it, however, I get this error message: WicketMessage: Component imageMap must be applied to a tag of type 'img', not '' (line 0, column 0) [markup = file:/C:/eclipse-workspace/Spacegame3/web/WEB-INF/classes/mcv/wicket/spacegame/UniverseMapPanel.html, index = 4, current = '' (line 6, column 5)] But when I create the ImageMap with the image's wicket:id instead of its own, I get this error: java.lang.IllegalArgumentException: A child with id 'universeMap' already exists: So should I remove the wicket Image? That makes no sense, because then how would the know what image to show? So basically, I'm stumped as to how to use ImageMap.

But you can modify the src tag like below. Would that help?
WebMarkupContainer img = new ImageMap("image") {
private static final long serialVersionUID = 1L;
@Override protected void onComponentTag(final ComponentTag tag){
super.onComponentTag(tag);
tag.put("src", YOUR_VERY_OWN_URL);
}
};

Not a lot. I want to treat my image in the same way as any other
Wicket Image, and in my particular case, that means linking it to
an RenderedDynamicImageResource.
The problem is that the ImageMap needs to be applied to an img tag,
which means I can't apply an Image to that tag anymore, but ImageMap
doesn't provide anywhere near the functionality that Image does. It
should. I see this as a serious bug in ImageMap, and not just
some unavoidable limitation that needs to be worked around. The big
question is how to fix this.
I've got a couple of options:
1: Since ImageMap is applied to an img tag, ImageMap needs to implement
the same functionality as Image. The best way to do that by simply
making it inherit, but that's a problem since ImageMap already extends
WebMarkupContainer. No idea what WebMarkupContainer does, but there's
probably a very good reason for it. Also, there seems to be a big
difference in the way Image and ImageMap are rendered. ImageMap uses
onRender(), whereas Image uses onComponentTag(). I don't know enough
about the inner workings of Wicket to know what that means.
2: Since an ImageMap is something completely different from an Image,
it should not apply to an img tag, but to a map tag, and Image needs to
have a method to link it to an ImageMap. Accept that the current
ImageMap was based on a bad idea, and fix it properly.
I think the second is better and cleaner, and I have a better idea of
how to do it. The problem is that it requires some big changes: Image
needs an extra method, compatibility with the old ImageMap will break,
and you need to add a tag to your markup.
I'm not completely happy with the need to add a tag, and would
like to be able to simply add an ImageMap to an Image and have that
work, but considering the difference between onRender() and
onComponentTag(), I'm not sure that's possible. On the other hand,
web designers will probably like having an actual imagemap in their
markup.
Should I be posting this to the dev list perhaps?

difference in the way Image and ImageMap are rendered. ImageMap uses
onRender(), whereas Image uses onComponentTag(). I don't know enough
about the inner workings of Wicket to know what that means.
2: Since an ImageMap is something completely different from an Image,
it should not apply to an img tag, but to a map tag, and Image needs to
have a method to link it to an ImageMap. Accept that the current
ImageMap was based on a bad idea, and fix it properly.
I think the second is better and cleaner, and I have a better idea of
how to do it. The problem is that it requires some big changes: Image
needs an extra method, compatibility with the old ImageMap will break,
and you need to add a tag to your markup.
I'm not completely happy with the need to add a tag, and would
like to be able to simply add an ImageMap to an Image and have that
work, but considering the difference between onRender() and
onComponentTag(), I'm not sure that's possible. On the other hand,
web designers will probably like having an actual imagemap in their
markup.
I'm currently working on option 2, and it's looking like a pretty
extensive rewrite.
Should I be posting this to the dev list perhaps? I have already created
a Jira issue for this.

But you can modify the src tag like below. Would that help?
WebMarkupContainer img = new ImageMap("image") {
private static final long serialVersionUID = 1L;
@Override protected void onComponentTag(final ComponentTag tag){
super.onComponentTag(tag);
tag.put("src", YOUR_VERY_OWN_URL);
}
};
Not a lot. I want to treat my image in the same way as any other
Wicket Image, and in my particular case, that means linking it to
an RenderedDynamicImageResource.
The problem is that the ImageMap needs to be applied to an img tag,
which means I can't apply an Image to that tag anymore, but ImageMap
doesn't provide anywhere near the functionality that Image does. It
should. I see this as a serious bug in ImageMap, and not just
some unavoidable limitation that needs to be worked around. The big
question is how to fix this.
I've got a couple of options:
1: Since ImageMap is applied to an img tag, ImageMap needs to implement
the same functionality as Image. The best way to do that by simply
making it inherit, but that's a problem since ImageMap already extends
WebMarkupContainer. No idea what WebMarkupContainer does, but there's
probably a very good reason for it. Also, there seems to be a big
difference in the way Image and ImageMap are rendered. ImageMap uses
onRender(), whereas Image uses onComponentTag(). I don't know enough

Can i add javascript code to the shapelink markup used by ImageMap?
Hi *, i try to implement the following. - a background image is displayed. - the image is overlayed by some links - if mouse "hits" a link area the background is overlayed by a gray film - if mouse "leaves" the link area the gray film disappears - if link area is clicked the background image will be exchanged by an image with this area permanently marked I use an imagemap for now. Everything works fine but the onmouseover and onmouseout scripts. I have to add them to the markup. But i can not access it. ImageMap is final and is not using the customization concepts of other wicket components. Can someone help me out here?

Re: Can i add javascript code to the shapelink markup used by ImageMap?
I found a solution, maybe it's a hack, but it works. I manipulate the result of getURL Method of assigned link component. This string will be added to the area markup. I simply add the closeTag for href and then add the scripts for onmouseover and onmouseout. Hope this helps others 2.
