在SWT中需要ComboBoxCellEditor多选功能

Question

enter image description here我正在使用treeviewer，在此查看器中使用comboBoxCellEditor.i想要comboBoxCellEditor中的multiSelection功能。请建议。

  ArrayList<String> arrList = new ArrayList<String>(Arrays.asList  ("WINDOWS_WEB","WINDOWS_NONWEB","ANDROID_NATIVE","ANDROID_WEB"));
  editor = new ComboBoxViewerCellEditor(this.viewer.getTree(), SWT.READ_ONLY);
  editor.setContentProvider(new ArrayContentProvider());
  editor.setInput(arrList);
