gtk:window-skip-pager-hint (object)

object -- a gtk:window widget
setting -- true to keep this window from appearing in the pager

The accessor for the skip-pager-hint slot gets or sets whether the window should not be in the pager. Windows may set a hint asking the desktop environment not to display the window in the pager. This function sets this hint.

A "pager" is any desktop navigation tool such as a workspace switcher that displays a thumbnail representation of the windows on the screen.
