How can I cut/copy/paste TreeStore rows using clipboard?
The clipboard accepts text or image data, not an arbitrary object. The trick is to create a text representation of selected tree rows and copy it into clipboard. When pasting, create tree rows based on the text obtained from clipboard. Ideal format for this is XML, as a side effect the same serialization/deserialization method can be used when saving/loading the tree contents to/from a file. The XML tree should contain at least a root XML tag with format description and cell XML tags for each tree row. If the tree model contains columns with short values like checkboxes, put these values directly ito cell XML tags as parameters. If your model contains columns with potentially long text, you can add a special data XML tag as a child of every cell XML tag.
