| Another way to receive external image resources is to use the corresponding component with a model which contains the target URL. |
| |
| The ExternalImage and ExternalSource components which are available since Wicket 7.2.0 / Wicket 8.0.0 fulfill that task. |
| |
| The following example demonstrates the usage of a CompoundPropertyModel with the model object _ImageSrc_ The model object, bound to surrounding component / page, contains an attribute named _url_ which is read by the component: |
| |
| Java: |
| [source,java] |
| ---- |
| ImageSrc imageSrc = new ImageSrc(); |
| imageSrc.setUrl("http://www.google.de/test.jpg"); |
| setDefaultModel(new CompoundPropertyModel<>(imageSrc)); |
| add(new ExternalImage("url")); |
| ---- |
| |
| HTML: |
| [source,java] |
| ---- |
| <img wicket:id="url" /> |
| ---- |
| |
| The ExternalImage can also be constructed by passing in a Model (src) and Model of List (srcSet). For ExternalSource only the srcSet is available. |
