如何填充 CheckedTreeSelectionDialog
我正在编写一个测试来学习如何使用 CheckedTreeSelectionDialog。这是代码。
CheckedTreeSelectionDialog dialog =
new CheckedTreeSelectionDialog(shell, new LabelProvider(), new TreeContentProvider() );
dialog.setTitle("Tree Selection");
dialog.setMessage("Select the elements from the tree:");
ElementTree et = new ElementTree();
et.createElement(new Path("element_1"), "element_1");
dialog.setInput(dt);
dialog.open();
但我得到了异常：
org.eclipse.swt.SWTException: 无法执行可运行 (java.lang.NoClassDefFoundError: org/eclipse/pde/internal/ui/elements/TreeContentProvider)
我真的很感谢任何提示！
谢谢！

But I get the exception:

I really appreciate any hint!
Thanks!

您不能使用 org.eclipse.pde.internal.ui.elements.TreeContentProvider 类，因为它仅适用于 Eclipse PDE（包“internal”中的类不适合由客户使用）。
相反，您应该创建自己的 TreeContentProvider，实现接口 org.eclipse.jface.viewers.ITreeContentProvider，就像您对 TreeViewer 所做的那样。教程位于此处。
You can't use the class
org.eclipse.pde.internal.ui.elements.TreeContentProviderbecause it's only available for Eclipse PDE (the classes that are in a package 'internal' are not intended to be used by client).Instead you should create your own TreeContentProvider, implementing the interface
org.eclipse.jface.viewers.ITreeContentProvider, as you would do for aTreeViewer. A tutorial is here.
