Struct gtk4::CellView

pub struct CellView { /* private fields */ }

👎Deprecated: Since 4.10

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.

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).

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).
