ItemGrid

Item Grid displays items of a container in a grid. Each cell can be rendered individually with a dedicated component.

Vaadin 14 version of this is a part of SuperFields

Item Grid is a data component (AbstractSelect). The items of the container data source are displayed in a grid.

The following properties of Item Grid can be modified:

• number of columns (setColumns / getColumns)
• whether or not items can be selected (setSelectable / isSelectable)
• currently selected item id (getValue / setValue)
• multi-selection (isMultiSelect / setMultiSelect) - from version 0.3.0
• no selection allowance (isNullSelectionAllowed / setNullSelectionAllowed) - from version 0.3.0
• item component generator (getItemComponentGenerator / setItemComponentGenerator), an interface with one method: getComponentForItem(Object itemId, Item item, boolean selected) which returns a com.vaadin.ui.Component

The following is on a todo list:

• allow customisation of built-in style names
• reordering items with drag and drop

The source code is included in the jar file and can be found in the issue tracker.

Sample code

ItemGrid grid = new ItemGrid();

grid.setContainerDataSource(myContainer);

// selectable is true by default
grid.setSelectable(false);

// three columns by default
grid.setColumns(5);
