![]() ![]() Just change to implement ISelectionChangedListener to work on selection. The key thing here is to use the selection as the argument to collapseToLevel / expandToLevel. There are three constructors in the TreeViewer class that you can use to create TreeViewers: TreeViewer(Composite parent) TreeViewer(Composite parent. The following code examples are extracted from open source projects. llapseToLevel(sel, AbstractTreeViewer.ALL_LEVELS) ![]() ITreeContentProvider treeProvider = (ITreeContentProvider)provider If (provider instanceof ITreeContentProvider) IContentProvider provider = treeViewer.getContentProvider() A concrete tree-structured viewer based on an SWT Tree control with checkboxes on each node. I tried getItems () and setExpand (true), but not could get it to work. How do I traverse all the nodes in the tree. TreeViewer treeViewer = (TreeViewer)event.getViewer() I am playing with a jface snippet that simply creates a jface tree. Object sel = selection.getFirstElement() ![]() If (selection = null || selection.isEmpty()) touch file. treeview copy-paste Im currently running into a problem: I have a MultiSelectTreeView and I can modify the text on the node by double-clicking it (but leaving some time in between) like in normal Windows when you want to rename a file. If I start my program and do an expandAll() on the tree, then manually create a new file (in a seperate console window eg. IStructuredSelection selection = (IStructuredSelection)event.getSelection() I have a simple directory/file list program that is displayed in a JFace treeview. This is what I use for double click: public class TreeDoubleClickListener implements void doubleClick(final DoubleClickEvent event) For a JFace TreeViewer you should use a ISelectionChangedListener or a IDoubleClickListener - do not use the underlying Tree listeners as they may not interact correctly with the viewer. ![]()
