Re: Dunamic neted List Views
ok as usual I bet myself to it, here is the answer :
Basically use a ListView over a ListView!
@Override
public void renderMenu() {
IModelMenuItemState modelState = getState();
final MenuItemState rootState = modelState.getObject();
//Add all menu state objects as Ordered List / sub lists
//Model MenuItems per Level (layer)
ListListMenuItemState menuLayers = new
ArrayListListMenuItemState();
{
MenuItemState state = rootState;
do {
menuLayers.add(state.getChildren());
state = menuHelper.getFirstFertileChild(state);
} while(state != null); //Keep going (DFS) till Menu
node bares no child
}
//Render:
final ListViewListMenuItemState multiLevelMenuContainer =
new
ListViewListMenuItemState(menuContainer, menuLayers) {
@Override
protected void populateItem(final
ListItemListMenuItemState
menuLayerComponent) {
//Add levels layer by layer (each layer in a
different div on mark-up.
Items in same layer get same styling
//TODO : Work on mark-up styling for final
render details.
menuLayerComponent.add(new
ListViewMenuItemState(menuItems,
menuLayerComponent.getModelObject()) {
@Override
public void populateItem(final
ListItemMenuItemState
childMenuComponent) {
final MenuItemState
childItemState =
childMenuComponent.getModelObject();
childMenuComponent.add(new Label(name,
childItemState.getMenuItem().getName()));
childMenuComponent.add(new StaticImage(img,
new
Model(childItemState.getMenuItem().getImg())) );
childMenuComponent.add(new StaticImage(rollOverImg,
new
Model(childItemState.getMenuItem().getRollOverImg())) );
childMenuComponent.add(new Label(selected,
Boolean.toString(childItemState.isSelected(;
}
});
}
};
add(multiLevelMenuContainer);
}
Markup code looks like this:
table wicket:id=menuContainer border='1'
trtd
ul wicket:id=menuItems
li/li
li /li
li /li
li /li
/ul
/td/tr
/table

Dunamic neted List Views
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() {
IModelMenuItemState modelState = getState();
MenuItemState state = modelState.getObject();
//Add all menu state objects as Ordered List / sub lists.
add(new ListViewMenuItemState(menuItems,
state.getChildren()) {
@Override
public void populateItem(final ListItemMenuItemState
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
