我创建了一个FilterTree，当我输入正确的数据进行过滤和搜索时，它会显示正确的结果。但是当我输入不正确的数据时（例如：“asdjahsdkjhsaldkj”）。这将是错误的，我不知道为什么？
这是我的src：
@Override
public void createPartControl(final Composite parent) {
filterTree = new FilteredTree(parent, SWT.MULTI | SWT.H_SCROLL
| SWT.V_SCROLL, new PatternFilter(), true);
treeviewer = filterTree.getViewer();
treeviewer.setContentProvider(new TreeViewContentProvider());
treeviewer.setLabelProvider(new TreeViewLabelProvider());
treeviewer.setInput(treeData.getAllType());
treeviewer.addDoubleClickListener(this);
getSite().setSelectionProvider(treeviewer);
}
这是错误：
