gtk:cell-area-focus-cell (object)

object -- a gtk:cell-area object
renderer -- a gtk:cell-renderer object to give focus to

The accessor for the focus-cell slot gets or sets the currently focused cell for the area. This is generally called by implementations of the GtkCellAreaClass.focus() or GtkCellAreaClass.event() functions, however it can also be used to implement functions such as the gtk:tree-view-set-cursor-on-cell function.
