You can use the same technique described in http://cwiki.apache.org/WICKET/forms-with-dynamic-elements.html to dynamically add components to a page.
Wicket xhtml tag <wicket:container> comes in handy on these cases. Bellow is a simple example of a page with dynamic components:
MasterPage.java
| Code Block |
|---|
public class MasterPage extends WebPage
{
public MasterPage()
{
List<Component> components = new ArrayList<Component>();
components.add( new Component() );
components.add( new Component() );
add( new ListView( "components", components )
{
protected void populateItem(ListItem item)
{
item.add( (Component)item.getModelObject() );
}
});
}
}
|
MasterPage.html
| Code Block | ||||
|---|---|---|---|---|
| ||||
<html> <body> <wicket:container wicket:id="components"> <wicket:container wicket:id="component"/> </wicket:container> </body> </html> |
Component.java
| Code Block |
|---|
public class Component extends Panel
{
public Component()
{
super( "component" );
add( new Label( "name" ), "component 1" );
}
}
|
Component.html
| Code Block | ||||
|---|---|---|---|---|
| ||||
<html> <wicket:panel> <span wicket:id="name">component name</span> </wicket:panel> </html> |
