Examples of org.eclipse.jface.viewers.Viewer

org.eclipse.jface.viewers.Viewer
A viewer is a model-based adapter on a widget.
A viewer can be created as an adapter on a pre-existing control (e.g., creating a ListViewer on an existing List control). All viewers also provide a convenience constructor for creating the control.

Implementing a concrete viewer typically involves the following steps:
- create SWT controls for viewer (in constructor) (optional)
- initialize SWT controls from input (inputChanged)
- define viewer-specific update methods
- support selections (setSelection, getSelection)

  @Override
  public void onFabricConnected() {
    RefreshableUI refreshableUI = getRefreshableUI();
    if (refreshableUI instanceof HasViewer) {
      HasViewer hv = (HasViewer) refreshableUI;
      Viewer viewer = hv.getViewer();
      final Fabric fabric = this;
      if (viewer instanceof CommonViewer) {
        final CommonViewer cv = (CommonViewer) viewer;


        UIJob job = new UIJob("Connecting to " + this + "...") {

      Viewers.expand(viewer, node, 2);
