Adding a model to a custom panel

[Dane Laverty]

I’m building a Panel called TaskPanel that will display the contents of my
Task class. This simple Panel has a single constructor and a method, that
looks like this:

public class TaskPanel extends Panel {

    Task task;

    public TaskPanel(String id, final Task task) {
        super(id);
        add(new Label("name", task.getName()));
        add(new Label("description", task.getDescription()));
        add(new Label("assignedTo", task.getAssignedTo()));

        this.task = task;
    }

        @Override
    protected void onComponentTag(ComponentTag tag) {
        if (task.isSelected()) {
            // Do something
        }
    }
}


It seems like I should make Task the model for the Panel, but I'm having
trouble finding information on how to connect them. I imagine it should look
something like this:

public class TaskPanel extends Panel {

    public TaskPanel(String id, IModel task) {
        super(id, task);
        add(new Label("name", ???));
        add(new Label("description", ???));
        add(new Label("assignedTo", ???));
    }

        @Override
    protected void onComponentTag(ComponentTag tag) {
        if (getModel().???.isSelected()) {
            // Do something
        }
    }
}

Am I even heading in the right direction? Is this the right place to be
using a Model, or should I just stick with keeping the Task as an instance
variable in the class?
