Bug 103747 [Viewers] calling refresh on treeviewer in treeExpanded function, but it mess
I tried calling refresh on treeviewer in treeExpanded function. The result is it mess up the tree, there is only one children without a label. Code to reproduce: public void createPartControl(Composite parent) { viewer = new TreeViewer(parent, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL); drillDownAdapter = new DrillDownAdapter(viewer); viewer.setContentProvider(new ViewContentProvider()); viewer.setLabelProvider(new ViewLabelProvider()); viewer.setSorter(new NameSorter()); viewer.setInput(getViewSite()); viewer.addTreeListener(new ITreeViewerListener() { public void treeCollapsed(TreeExpansionEvent event) { } public void treeExpanded(TreeExpansionEvent event) { viewer.refresh(event.getElement()); }}); }
