/* Menu

* #Keywords: action, zoom

|
|
* Demonstrates how to add a context menu to a custom widget
|
|
* and connect it with widget actions.
|
|
*
|
|
* The custom widget we create here is similar to a GtkPicture,
|
|
* but allows setting a zoom level for the displayed paintable.
|
|
*
|
|
* Our context menu has items to change the zoom level.
