问题
How do I paste HTML to the clipboard so that it is recognized as HTML in applications such as Open Office and MS Word? It is possible when using gtkhtml or gecko if you've already rendered it, but I need a straight GTK+ solution.
回答1:
You call gtk_clipboard_set_with_data or gtk_clipboard_set_with_owner, passing a GtkTargetEntry with "text/html" as the value for the target field.
It's good practice to also provide "UTF8_STRING" and "STRING" targets for applications that don't support HTML.
Here's an example of some code that does this: GEdit HTML clipboard plugin.
