Eclipse plugin Eclipse JFace Treeviewer视图在调用setSelection时未选择
我的eclipse插件中有一个带有treeviewer的视图，我正在尝试使用iSelectService根据编辑器中的选择在treeviewer中选择一行。我能够找到必须选择的元素，并在下面的代码段中尝试了以下操作：Eclipse plugin Eclipse JFace Treeviewer视图在调用setSelection时未选择,eclipse-plugin,eclipse-rcp,jface,Eclipse Plugin,Eclipse Rcp,Jface,我的eclipse插件中有一个带有treeviewer的视图，我正在尝试使用iSelectService根据编辑器中的选择在treeviewer中选择一行。我能够找到必须选择的元素，并在下面的代码段中尝试了以下操作： v.setExpandedState(file, true); v.refresh(); v.setSelection(new StructuredSelection(iDialogSettings), true); 我还检查了视图的Contentprovider，它正在返回
