Expand description
List views use widgets to display their contents.
You can use Box instead
A widget displaying a single row of a GtkTreeModel
A CellView displays a single row of a TreeModel using a CellArea
and CellAreaContext. A CellAreaContext can be provided to the
CellView at construction time in order to keep the cellview in context
of a group of cell views, this ensures that the renderers displayed will
be properly aligned with each other (like the aligned cells in the menus
of ComboBox).
CellView is Orientable in order to decide in which orientation
the underlying CellAreaContext should be allocated. Taking the ComboBox
menu as an example, cellviews should be oriented horizontally if the menus are
listed top-to-bottom and thus all share the same width but may have separate
individual heights (left-to-right menus should be allocated vertically since
they all share the same height but may have variable widths).
CSS nodes
GtkCellView has a single CSS node with name cellview.
Properties
cell-area
The CellArea rendering cells
If no area is specified when creating the cell view with gtk_cell_view_new_with_context()
a horizontally oriented CellAreaBox will be used.
since 3.0
Readable | Writeable | Construct Only
cell-area-context
The CellAreaContext used to compute the geometry of the cell view.
A group of cell views can be assigned the same context in order to ensure the sizes and cell alignments match across all the views with the same context.
ComboBox menus uses this to assign the same context to all cell views
in the menu items for a single menu (each submenu creates its own
context since the size of each submenu does not depend on parent
or sibling menus).
since 3.0
Readable | Writeable | Construct Only
draw-sensitive
Whether all cells should be draw as sensitive for this view regardless of the actual cell properties (used to make menus with submenus appear sensitive when the items in submenus might be insensitive).
since 3.0
