TreeViewerColumn colEdit= new TreeViewerColumn (viewer, column);
colEdit.setLabelProvider(new ColumnLabelProvider(){
   
    @Override
    public void update(ViewerCell cell) {

        TreeItem item = (TreeItem) cell.getItem();
        Button btnEdit= new Button((Composite) cell.getViewerRow().getControl(),SWT.NONE);
        btnEdit.setText("Edit");

        TreeEditor editor = new TreeEditor(item.getParent());
        editor.grabHorizontal  = true;
        editor.grabVertical = true;
        editor.setEditor(btnEdit, item, cell.getColumnIndex());
        editor.layout();

        btnEdit.addSelectionListener(new SelectionAdapter() {
            @Override
            public void widgetSelected(SelectionEvent e) {
                // How to get current row element.
                TreeItem[] selection = treeViewer.getTree().getSelection(); // (Selection is empty, because click on button and selection not happened)
            }
        });
    }
});

treeViewer.getTree().getSelection();返回空，因为添加了按钮控件的树编辑器，而按钮单击行选择没有发生。

cell.getElement()在处理程序方法中返回 null。

btnEdit.setData 可以帮助我，但是有什么方法可以获取当前行（元素）单击哪个按钮单击事件？
