TreePath的用法

TreeSelection sel = (TreeSelection)event.getSelection(); if (sel.getPaths().length > 0) { int count = sel.getPaths()[0].getSegmentCount(); if (count >= 2) { TreePath tp = sel.getPaths()[0]; ValuesMappingInfo info = (ValuesMappingInfo)tp.getLastSegment();/*etFirstSegment();*/ // IFolder fold = (IFolder)tp.getFirstSegment(); // nodeName = fold.getName(); // selectedObject = sel.getFirstElement(); // getButton(IDialogConstants.OK_ID).setEnabled(true); // } // else{ // getButton(IDialogConstants.OK_ID).setEnabled(false); System.out.println(""); } }
