Hi,
I just developed a Menu; that is nested many levels. At the point of
rendering in my code I'm slightly confused. ok, Let the code talk:
(The following code assumes a domain model with "MenuItemState" which is
hiararchial has children. And each child node is a "MenuItemState". The
child can either have "null" or further children.
The renderMenu() is called by a Panel.)
@Override
public void renderMenu() {
IModel<MenuItemState> modelState = getState();
MenuItemState state = modelState.getObject();
//Add all menu state objects as Ordered List / sub lists.
add(new ListView<MenuItemState>("menuItems",
state.getChildren()) {
@Override
public void populateItem(final ListItem<MenuItemState>
wrappedChildComponent) {
final MenuItemState childItemState =
wrappedChildComponent.getModelObject();
wrappedChildComponent.add(new Label("name",
childItemState.getMenuItem().getName()));
wrappedChildComponent.add(new
StaticImage("img",
new
Model(childItemState.getMenuItem().getImg())) );
wrappedChildComponent.add(new
StaticImage("rollOverImg",
new
Model(childItemState.getMenuItem().getRollOverImg())) );
wrappedChildComponent.add(new Label("selected",
Boolean.toString(childItemState.isSelected())));
}
});
.. now I can add the children like:
wrappedChildComponent.add(new
ListView("nestedItemsFor_"+childItemState.getMenuItem().getName(),
childItemState.getChildren() {...} );
Code: Current markup code::
<table>
<tr wicket:id="menuItems">
<td></td>
<td> </td>
<td> </td>
<td> </td>
</tr>
</table>
..but how will the above markup code generate the name for the nestedItem
Component & know if the item has children. Should I just inject markup
mylsef or using ListView<> can achieve this cleanly?
I want to introduce nesting from my Model into the markup using ListView!
Ideas?! (I dont wanna keep posting answers to my own questions so quick
replies would help :) ) heh
