我認爲我可能有一個解決方案。以下類是內聯文本編輯器。使用在doCreateElementObservable
中添加的偵聽器來獲取模型bean(所有實例)的更改。我的eclipse編輯器只需添加其自己的變更監聽器,以便隨時通知。
public class InlineEditingSupport extends ObservableValueEditingSupport
{
private CellEditor cellEditor;
private String property;
private DataBindingContext dbc;
IChangeListener changeListener = new IChangeListener()
{
@Override
public void handleChange(ChangeEvent event)
{
for (ITableEditorChangeListener listener : listenersChange)
{
listener.changed();
}
}
};
public InlineEditingSupport(ColumnViewer viewer, DataBindingContext dbc, String property)
{
super(viewer, dbc);
cellEditor = new TextCellEditor((Composite) viewer.getControl());
this.property = property;
this.dbc = dbc;
}
protected CellEditor getCellEditor(Object element)
{
return cellEditor;
}
@Override
protected IObservableValue doCreateCellEditorObservable(CellEditor cellEditor)
{
return SWTObservables.observeText(cellEditor.getControl(), SWT.Modify);
}
@Override
protected IObservableValue doCreateElementObservable(Object element, ViewerCell cell)
{
IObservableValue value = BeansObservables.observeValue(element, property);
value.addChangeListener(changeListener); // ADD THIS LINE TO GET CHANGE EVENTS
return value;
}
private List<ITableEditorChangeListener> listenersChange = new ArrayList<ITableEditorChangeListener>();
public void addChangeListener(ITableEditorChangeListener listener)
{
listenersChange.remove(listener);
listenersChange.add(listener);
}
public void removeChangeListener(ITableEditorChangeListener listener)
{
listenersChange.remove(listener);
}
}
