Attributes let you set the properties /// in flexible ways. They can just be set to constant values like regular /// properties. But they can also be mapped to a column of the underlying /// tree model with `gtk_cell_layout_set_attributes()`, which means that the value /// of the attribute can change from cell to cell as they are rendered by /// the cell renderer. Finally, it is possible to specify a function with /// [`CellLayoutExt::set_cell_data_func()`][crate::prelude::CellLayoutExt::set_cell_data_func()] that is called to determine the /// value of the attribute for each cell that is rendered. /// /// # GtkCellLayouts as GtkBuildable /// /// Implementations of GtkCellLayout which also implement the GtkBuildable /// interface ([`CellView`][crate::CellView], [`IconView`][crate::IconView], [`ComboBox`][crate::ComboBox], /// [`EntryCompletion`][crate::EntryCompletion], [`TreeViewColumn`][crate::TreeViewColumn]) accept GtkCellRenderer objects /// as `<child>` elements in UI definitions.
