Simplify all view model APIs and always return G_TYPE_OBJECT as the item-type for every model. It turns out nobody uses item-type anyway. So instead of adding lots of APIs, forcing people to think about it and trying to figure out how to handle filter or map models that modify item types, just having an easy life is a better approach. All the models need to be able to deal with any type of object going through anyway.

|
* @short_description: Interface for managing shortcuts
|
|
*
|
|
* The GtkShortcutManager interface is used to implement
|
|
* shortcut scopes.
|
|
*
|
|
* This is important for #GtkNative widgets that have their own surface,
|
|
* since the event controllers that are used to implement managed and
|
|
* global scopes are limited to the same native.
|
|
*
|
|
* Examples for widgets implementing #GtkShortcutManager are #GtkWindow
|
|
* and #GtkPopover.
