Examples of com.vaadin.data.Container.removeItem()

com.vaadin.data.Container.removeItem()

Removes the Item identified by ItemId from the Container.

Containers that support filtering should also allow removing an item that is currently filtered out.

This functionality is optional.

@param itemId ID of the Item to remove @return true if the operation succeeded, falseif not @throws UnsupportedOperationException if the container does not support removing individual items

                Object[] itemIds = containerDataSource.getItemIds().toArray();
                @SuppressWarnings("unused")
                int c = 0;
                for (int i = 0; i < itemIds.length; i++) {
                    if (i > 19) {
                        containerDataSource.removeItem(itemIds[i]);
                    }
                }
            }
        });

                }


                // Remove the item from the source container and
                // add it to the tree's container
                Container sourceContainer = t.getSourceContainer();
                sourceContainer.removeItem(sourceItemId);
                tree.addItem(beanItem);
                InventoryObject bean = (InventoryObject) beanItem.getBean();
                tree.setChildrenAllowed(beanItem, bean.isContainer());


                // Drop right on an item -> make it a child

                    tree1.setChildrenAllowed(name, false);


                    /*
                     * Remove the item from table

                    sourceContainer.removeItem(itemId);


                    itemId = name;


                }


                // move item from table to category'
                tree.addItem(sourceItemId);
                tree.setParent(sourceItemId, targetItemId);
                tree.setChildrenAllowed(sourceItemId, false);
                sourceContainer.removeItem(sourceItemId);
