I have to display a custom build Image generated by another API. The way I
hae thought of it right now is by extending RenderedDynamicImageResource.
Here is the way I work with it :
Create a panel containing an Image with the blank ressource. Then, clicking
on a link, I refresh the panel, which should also refresh the image to
reflect the change. The problem is that whatever happen, the render of the
graph is not called. I mean, I set Height and width correctly, but the
image does not rerender. It is possible that RenderedDynamicImageRessource
is not Ajax ready and if so, what can I use?
Here is the panel :
public GraphToDiplay(String id) {
super(id);
_graphImageRessource = new GraphImageRessource();
Image graph = new NonCachingImage("graph", new
ProcessGraphImageRessource());
graph.setOutputMarkupId (true);
add(graph);
}
public void onAttach()
{
Graph graph = getGraph();
_graphImageRessource.setGraph (graph);
}
Here is the Ressource :
public ProcessGraphImageRessource()
{
super(3, 3);
}
public void setGraph(Graph graph)
{
_graph = graph;
setWidth(graph.getWidth ());
setHeight(graph.getHeight ());
invalidate();
System.out.println("Setting height{" + graph.getHeight () + "} and
width{" + graph.getWidth () + "}");
}
protected boolean render (Graphics2D graphics2D)
{
System.out.println("Rendering");
if(_graph != null)
{
if(_graph.getWidth () == this.getWidth () && _graph.getHeight ()
== this.getHeight ())
{
System.out.println("Suppose to paint this graph now...");
_graph.paintVisibleContent (graphics2D);
return true;
}
else
{
this.setWidth (_graph.getWidth ());
this.setHeight(_graph.getHeight ());
return false;
}
}
else
{
return true;
}
}
Thanks in advance
Marc
