CommanderGrid Add-on
CommanderGrid
Uses performance of flat Grid (paging) to show hierarchical data by showing only one hierarchy level at time. To be used with a heavy com.vaadin.data.provider.BackEndDataProvider which is not optimised to show all children at once in a com.vaadin.ui.TreeGrid.
Sample code
HierarchicalFileDataProvider dataProvider = new HierarchicalFileDataProvider(new File("/Users")); CommanderGrid<File, FileFilter> grid = new CommanderGrid<>(BeanPropertySet.get(File.class), dataProvider) .withFirstColumn("name"); grid.addKeyAction(ShortcutAction.KeyCode.ENTER, ShortcutAction.ModifierKey.SHIFT, () -> grid.asSingleSelect().getSelectedItem().ifPresent(grid::goInto) ); grid.addKeyAction( ShortcutAction.KeyCode.BACKSPACE, ShortcutAction.ModifierKey.SHIFT, grid::goToParentFolder ); TextField filterComponent = new TextField(); filterComponent.addValueChangeListener(event -> dataProvider.setFilter(file -> file.getName().contains(event.getValue())) ); grid.getHeaderRow(0).getCell("name").setComponent(filterComponent);
