Demonstrates a simply TreeViewer with one column. It describes all important classes used for all Tree-like JFace-Viewers (LabelProvider,ITreeContentProvider)
Demonstrates tables with more than one column and the usage of ITableLabelProvider
Demonstrates how the selection can be hidden when the user clicks in a table-row/column which doesn't hold any information. The standard behavior of SWT-Table is to leave the selection on the last column. This snippet removes the selection if the user clicks in an area not selectable
Demonstrates how to create a different context menu depending on which item in the tree is currently selected this can also be used with a table of course
Demonstrates first use case for the OwnerDraw-Support added to JFace in 3.3 (available at SWT-Level since 3.2). This example uses the Viewers API in this special case the OwnerDrawLabelProvider to make items with more than one line of text.
Demonstrates how you can use inline editing in tables with multiple columns that require to use SWT.FULL_SELECTION but hiding the selection from the user.
Demonstrates how you can scroll a TableViewer to the specific model element using TableViewer#reveal(Object)
Demonstrates minimal example when trying to add inline editing to tables to get familiar with the various classes needed (3.2 API)
Demonstrates usage of the OwnerDraw-Support feature provided by JFace in 3.3(available in SWT since 3.2). This example uses the Viewers API in this special case the OwnerDrawLabelProvider.
Demonstrates usage of custom tooltip support in 3.3 used to provide a tooltip for each cell in TableViewer
Demonstrates usage of none mandatory LabelProviders in TableViewers to set colors and fonts with 3.2-API

Demonstrates usage of none mandatory LabelProviders in TreeViewers to set colors and font with 3.2-API
Demonstrates usage of custom tooltip support used to provide a tooltip for each cell in a TreeViewer
Demonstrates hiding and showing columns (animated)
Demonstrates adding/removing of columns in conjunction with the inline editing with JFace-API
Demonstrates the base classes of 3.3 API
Demonstrates how one can use the 3.3 API to add tab-editing support to your viewer
Press Tab to jump from cell to cell
Demonstrates all fancy things one can do with the 3.3 API (Tab-Editing, Keyboard-Navigation from Cell to Cell, Editor-Activation with the Keyboard)
Demonstrates usage of the ComboBoxCellEditor in JFace-Viewers
Demonstrates usage of JFace-Viewers in "virtual" mode with an ordinary content provider (often the bottleneck is not the model but the UI). Using these Virtual viewers in conjunction with an ordinary content provider has the advantage that Sorting and Filtering are supported in 3.3.
Demonstrates usage of JFace-Viewer virtual mode with a lazy content provider
Demonstrates creation of tooltips for cells for pre 3.3 users
Demonstrates different CellEditor-Types in one COLUMN of JFace-Viewers
Demonstrates keyboard navigation in TableViewers using a TableCursor showing the flexibility of the cell navigation support
You also need these classes:
Demonstrates keyboard navigation by highlighting the currently selected cell with a focus border showing once more the flexibility of the cell navigation support
You also need:
Demonstrates customizability of the 3.3 JFace-Support for cell tooltips using the Browser-Widget and presenting HTML
Demonstrates a very simple usage of ListViewer
Demonstrates sorting (ascending/descending) in TableViewers by clicking the column header.
Demonstrates how to achieve alternating row-colors with TableViewer. It can also be used in conjunction with virtual-bits to even work with big tables (e.g. 100,000 rows in this example). In addition, this snippet provided a button that will demonstrate the usage of viewer filters.
Demonstrates the JFace 3.3 keyboard editing support for Trees without columns. Tabbing from editor to editor is supported since 3.4. In addition, this snippet provided a button that shows how to enter in edit mode programmatically.
Demonstrates the JFace 3.3 keyboard editing support for Tables without columns. Tabbing from editor to editor is supported since 3.4.
You also need:
Demonstrates how a TableViewer with a sorter can be filled from a NON-UI thread
Demonstrates how to update a viewer from a long-running task (which is executed in a thread) and calls back to the UI-Thread using "asyncExec".
Demonstrates the usage of ILazyContentProvider in conjunction with a Virtual-TreeViewer. The snippet shows how using a lazy tree can minimize the memory footprint and maximize the speed when viewing large models.
Demonstrates how to overcome a limitation when it comes to key-navigation and CheckBoxEditors in 3.3.1.
This is a workaround for bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=198502
Demonstrates a LabelProvider-Type which uses StyleRanges. This Snippet requires SWT/JFace 3.4.
Demonstrates how you can add styled text by wrapping an existing label provider. This Snippet requires SWT/JFace 3.4.
Demonstrate how to center an image and create graphics in a cell using a technique called "owner draw".
Demonstrate how to start cell-editors on double click.
Demonstrate how to start up a cell editor with a context menu and not with mouse clicking on the cell.

Demonstrate hiding and showing columns and starting a cell editor programmatically.
Demonstrate a custom cell-editor which uses a real Checkbox-Button
You also need these classes:
Example of showing how easy cell-navigation with hidden cells is. Use the cursor keys to navigate between cells. Then use the context menu to hide a column.
Shows how to automatically reveal cells when navigating. Run the snippet and then edit the first cell by double-clicking. Pressing the tab key will advance to the next cell in edit mode and reveal the cell if it is not in the viewport.
Show how to use content-proposal inside a CellEditor
Full-featured native-looking viewer with checkboxes in an arbitrary column
You also need these classes:
Demonstrates usage of TextAndDialogCellEditor. The email column uses the TextAndDialogCellEditor; othe columns use ordinary TextCellEditor.
You also need these classes:
Show how to use ComboViewer and set an initial selection
A TreeViewer with observable collections as input, to demonstrate, how elements are replaced, especially what happens to selected items on replacement
A TreeViewer with observable collections as input, to demonstrate, how elements are replaced, especially what happens to selected items on replacement
A TableViewer that shows how to add a status icon to a Label with IStyledLabelProvider and DecorationOverlayIcon
Demonstrates usage of JFace 3.3 to show really cool ToolTips for your controls
For full fun you also need:
Demonstrates creation of ToolTips for Tables without using the JFace-Viewers API but only JFace-Tooltips
Demonstrates how to work with JFace-Wizards and fill a TableViewer from a Background-Thread without blocking the UI showing a progress bar in the meanwhile
Demonstrates a wizard with internal progress.
https://raw.githubusercontent.com/eclipse-platform/eclipse.platform.ui/master/examples/org.eclipse.jface.snippets/Eclipse%20JFace%20Snippets/org/eclipse/jface/snippets/viewers/FocusBorderCellHighlighter.java Demonstrates a wizard with internal progress using SubMonitor and subtasks.
