Examples with VisualRefreshEvent org.eclipse.nebula.widgets.nattable.layer.event.VisualRefreshEvent used on opensource projects

Example 1 with VisualRefreshEvent

use of org.eclipse.nebula.widgets.nattable.layer.event.VisualRefreshEvent in project nebula.widgets.nattable by eclipse.

the class DataChangeLayer method discardDataChanges.

 * Discards the tracked data changes. In case temporary data storage is
 * disabled, the applied changes are undone by restoring the previous values
 * via dedicated {@link UpdateDataCommand}s.
 */

Example 2 with VisualRefreshEvent

use of org.eclipse.nebula.widgets.nattable.layer.event.VisualRefreshEvent in project nebula.widgets.nattable by eclipse.

the class DataChangeLayer method saveDataChanges.

/**
 * Saves the tracked data changes. In case temporary data storage is enabled
 * this means the underlying data model is updated. Otherwise the stored
 * data changes are simply cleared.
 * <p>
 * <b>Note:</b> In case temporary data storage is disabled and a custom save
 * operation should be performed on save, a custom
 * {@link SaveDataChangesCommandHandler} should be registered that first
 * performs a custom action and afterwards calls this method to ensure a
 * clear state in this layer.
 * </p>
