/**
* SECTION:pager
* @short_description: a pager widget, showing the content of workspaces.
* @see_also: #WnckScreen
* @stability: Unstable
*
* A #WnckPager shows a miniature view of the workspaces, representing managed
* windows by small rectangles, and allows the user to initiate various window
* manager actions by manipulating these representations. The #WnckPager offers
* ways to move windows between workspaces and to change the current workspace.
*
* Alternatively, a #WnckPager can be configured to only show the names of the
* workspace instead of their contents.
*
* The #WnckPager is also responsible for setting the layout of the workspaces.
* Since only one application can be responsible for setting the layout on a
* screen, the #WnckPager automatically tries to obtain the manager selection
* for the screen and only sets the layout if it owns the manager selection.
* See wnck_pager_set_orientation() and wnck_pager_set_n_rows() to change the
* layout.
