| <h2>Tree</h2> |
| |
| <p> |
| The Tree widget can display structured data in a hierarchical view. |
| It supports checkboxes, resizeable and moveable columns, multi-selection mode, |
| on-demand data loading (so-called Virtual Trees), and more. |
| </p> |
| |
| <h3>Style Flags</h3> |
| |
| <p> |
| The style flag <code>CHECK</code> enables checkboxes. |
| </p> |
| <p> |
| The selection mode can be chosen by specifying either <code>SINGLE</code>, which is the default, or |
| <code>MULTI</code> to enable multi-selection. |
| </p> |
| |
| <h3>Virtual Trees</h3> |
| <p> |
| Trees can handle lots of data. |
| Too many rows can slow down rendering. |
| With virtual trees, only the range of visible rows is loaded from the server. |
| Everytime a new range of items becomes visible, the new information to display |
| is requested from the server. |
| </p> |
| |
| <h3>JFace TreeViewers</h3> |
| <p> |
| JFace viewers provide a model-view-controller separation. |
| For advanced uses, a TreeViewer is an alternative to using a plain SWT Tree. |
| The TreeViewer operates on an underlying Tree widget and performs all tasks |
| necessary for labeling, filtering, sorting, etc. |
| </p> |
| |
| <h3>Theming</h3> |
| <p> |
| The appearance of the Tree widget is highly customizeable. |
| Examples are: |
| </p> |
| <ul> |
| <li>Alternating row colors</li> |
| <li>Exchangeable indent icons</li> |
| <li>Configurable cell padding</li> |
| </ul> |
