- Parameters:
-
| event | The type of the key event. Recognised values are "key-press" and "key-release". |
| key | Character representation of the key. This is typically as produced by XKeysymToString. |

Sends a mouse event to the navigation interface.
Mouse event coordinates are sent relative to the display space of the related output area. This is usually the size in pixels of the window associated with the element implementing the Gst::Navigation interface.
- Parameters:
-
| event | The type of mouse event, as a text string. Recognised values are "mouse-button-press", "mouse-button-release" and "mouse-move". |
| button | The button number of the button being pressed or released. Pass 0 for mouse-move events. |
| x | The x coordinate of the mouse event. |
| y | The y coordinate of the mouse event. |

- Returns:
- A C++ instance that wraps this C instance.
