public class GridTreeViewer
extends org.eclipse.jface.viewers.AbstractTreeViewer
A concrete viewer based on an Grid control.

This class is not intended to be subclassed outside the viewer framework. It is designed to be instantiated with a pre-existing Grid control and configured with a domain-specific content provider, label provider, element filter (optional), and element sorter (optional).

Content providers for grid tree viewers must implement the ITreeContentProvider interface.

The current implementation does not support lazy content providers.

    • setAutoPreferredHeight

      public void setAutoPreferredHeight​(boolean autoPreferredHeight)
      When set to true, this grid viewer will ensure that each of the grid's items is always automatically sized to its preferred height. The default is false.

      Since this mechanism usually leads to a grid with rows of different heights and thus to a grid with decreased performance, it should only be applied if that is intended. To set the height of all items to a specific value, use Grid.setItemHeight(int) instead.

      When a column with activated word wrapping is resized by dragging the column resizer, the items are only auto-resized properly if you use GridViewerColumn to create the columns.

      When this method is called, existing rows are not resized to their preferred height. Therefore it is suggested that this method be called before rows are populated (i.e. before setInput).

    • getAutoPreferredHeight

      public boolean getAutoPreferredHeight()
      Returns:
      true if this grid viewer sizes its rows to their preferred height

      setAutoPreferredHeight(boolean)

    • doUpdateItem

      protected void doUpdateItem​(org.eclipse.swt.widgets.Item item, java.lang.Object element)
      Overrides:
