Class ActiveCellEditorRegistry

java.lang.Object

org.eclipse.nebula.widgets.nattable.edit.ActiveCellEditorRegistry

public class ActiveCellEditorRegistry
extends Object

This class is used to store the instance of the current active cell editor for inline editing. As the ICellEditor does not know about the NatTable instance it is activated in, and NatTable does not have some kind of global context to register this information to, it is currently not possible to solve this in another way.

On activating a cell editor for inline editing, the activated cell editor will be registered here. If the editor is closed, it needs to unregister itself.

Any position in code that needs to be aware of an open cell editor can request it from here. This is especially necessary for automatic closing of cell editors on other actions, e.g. trying to scroll with an activated editor which should lead to close the editor first.

This can cause serious side effects if you are trying to create a custom editor that is based on NatTable as editor control. This needs to be solved with some kind of NatTable context where such instance can be registered (e.g. Dependency Injection) and therefore will be addressed in a future architecture design.
