ItemLayout offers a way to generate components from data container. Generated components will be displayed in custom layouts such as Grid, Vertical or horizontal. To achieve that three custom components are available : - ItemGrid - use a gwt Grid to display items - column number can be specify - ItemHorizontal - use a gwt HorizonalPanel to display items - use a custom scroll bar - scroll interval can be specify - first index to display can be specify - ItemVertical (same as Horizontal but on vertical way) - use a gwt VerticalPanel to display items - use a custom scroll bar - scroll interval can be specify - first index to display can be specify Each component handles single or multi-select items, to do so you just need to add an ItemClickHandler. Next development : - Customize scroll buttons for ItemHorizontal and ItemVertical The original idea came from ItemGrid Addon available on vaadin directory but we need horizontal and vertical layout with custom scrollbar.
