How delete an item from SWT TreeViewer?

Question

我正在使用Eclipse Standard Widget Toolkit（ SWT ），我有一个包含项目的TreeView对象，并且双击事件（ addDoubleClickListener ）可以正常工作，但是我不知道如何实现右键单击以删除项目。

Answer 1

1. To listen to right clicks, use addMenuListener . Eclipse RCP has its own more advanced mechanisms, but this should be enough for your purposes.

2. In SelectionListener for your MenuItem , remove the item from your model and refresh the viewer.
