Vaadin TreeGrid
Component that adds tree-like functionality to Grid for displaying hierarchical data
TreeGrid is a UI component add-on for Vaadin 7. It adds the ability to display and edit hierarchical data source in the Grid component (similar to TreeTable's extension to Table).
Features:
- Basic functionality for displaying hierarchical data in Grid
- CSS configurable hierarchy indicators
- Expand/collapse functionality on mouse click
- Programmatically settable hierarchy column
- Keyboard navigation (Alt/Option + Arrow keys)
- Support for custom renderer on hierarchy column
- Support for custom depth calculation logic
- Support for custom collapse logic
Notes:
- This add-on relies on changes in Vaadin Framework 7.7.6
- This add-on is compiled with Java 7
Sample code
final TreeGrid grid = new TreeGrid(); // Container implementing Hierarchical and Indexed interfaces DemoContainer container = new DemoContainer(); grid.setContainerDataSource(container); // Set the column that shows the hierarchy information grid.setHierarchyColumn(DemoContainer.PROPERTY_LAST_NAME); grid.setColumnReorderingAllowed(true);
