Paste
| Chapter 20. The Clipboard |

## Paste

When the user asks to paste data from the `Clipboard`, you should request a specific format and provide a callback method which will be called with the actual data. For instance:

    void ExampleWindow::on_button_paste()
    {
      get_clipboard()->read_text_async(sigc::mem_fun(*this,
                  &ExampleWindow::on_clipboard_received));
    }

Here is an example callback method:

    void ExampleWindow::on_clipboard_received(Glib::RefPtr<Gio::AsyncResult>& result)
    {
      auto text = get_clipboard()->read_text_finish(result);
      //Do something with the pasted data.
    }

### Discovering the available formats

To find out what formats are currently available on the `Clipboard` for pasting, call the `get_formats()` method. Then call a `Gdk::ContentFormats` method to find out if a format that your application supports is available.
