    • E4SelectionListener

      @Inject public E4SelectionListener(org.eclipse.e4.ui.workbench.modeling.ESelectionService service, SelectionLayer selectionLayer, IRowDataProvider<T> rowDataProvider)

      rowDataProvider - The IRowDataProvider to access the selected row data.

  • Method Details

    • handleLayerEvent

      public void handleLayerEvent(ILayerEvent event)
      Description copied from interface: ILayerListener
      Handle an event notification from an ILayer
      Specified by:
      handleLayerEvent in interface ILayerListener
      Parameters:
      event - the event

    • isFullySelectedRowsOnly

      public boolean isFullySelectedRowsOnly()
      Returns:
      true if only fully selected rows should be used to populate the selection or if any selection should be populated. Default is true.

    • setFullySelectedRowsOnly

      public void setFullySelectedRowsOnly(boolean fullySelectedRowsOnly)
      Parameters:
      fullySelectedRowsOnly - true if only fully selected rows should be used to populate the selection false if any selection should be populated.

    • isHandleSameRowSelection

      public boolean isHandleSameRowSelection()
      Returns:
      true if a selection should only be handled by the ESelectionService if the row selection changes or if just another column is selected.

    • setHandleSameRowSelection

      public void setHandleSameRowSelection(boolean handleSameRowSelection)
      Parameters:
      handleSameRowSelection - true if a selection should only be handled by the ESelectionService if the row selection changes or if just another column is selected.

    • isProcessColumnSelection

      public boolean isProcessColumnSelection()
      Returns:
      true if column selection should trigger setting the selection via ESelectionService (that means basically a select all), false if not (needed for huge datasets to avoid a select all).

    • setProcessColumnSelection

      public void setProcessColumnSelection(boolean processColumnSelection)
      Configure whether column selections should start row selection processing or not.

      This is necessary to handle issues with huge datasets. Dependent on different configurations, selecting a column can cause the selection of all rows in a table, which would then lead to populate the whole dataset as selection via this provider. Setting the processColumnSelection flag to false will skip processing to avoid such issues.

      Parameters:
      processColumnSelection - true to process row selection in case of column selections (default) false to skip processing in case of column selections to avoid issues on large datasets.

    • isMultiSelection

      public boolean isMultiSelection()
      Returns:
      true if a list of data values should be set as selection or a single value.

    • setMultiSelection

      public void setMultiSelection(boolean multiSelection)
      Set this value to true if a list of values should be set as selection to the ESelectionService or false if only a single value object should be set.
      Parameters:
      multiSelection - true if a list of data values should be set as selection or a single value.
