CellViewProtocol

public protocol CellViewProtocol : CellLayoutProtocol, OrientableProtocol, WidgetProtocol

A widget displaying a single row of a GtkTreeModel

A GtkCellView displays a single row of a GtkTreeModel using a GtkCellArea and GtkCellAreaContext. A GtkCellAreaContext can be provided to the GtkCellView 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 GtkComboBox).

GtkCellView is GtkOrientable in order to decide in which orientation the underlying GtkCellAreaContext should be allocated. Taking the GtkComboBox 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.

The CellViewProtocol protocol exposes the methods and properties of an underlying GtkCellView instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see CellView. Alternatively, use CellViewRef as a lighweight, unowned reference if you already have an instance you just want to use.

    the property to get the value for

    Return Value

  • set(property:value:) Extension method

    Set the value of a CellView property. Note that this will only have an effect on properties that are writable and not construct-only!

CellView Class: CellViewProtocol extension (methods and fields)

  • getDisplayedRow() Extension method

    Returns a GtkTreePath referring to the currently displayed row. If no row is currently displayed, nil is returned.

    Declaration

    Swift

    @inlinable
func getDisplayedRow() -> TreePathRef!
    Show on GitHub
  • getDrawSensitive() Extension method

    Gets whether cell_view is configured to draw all of its cells in a sensitive state.

    Declaration

    Swift

    @inlinable
func getDrawSensitive() -> Bool
    Show on GitHub
  • getFitModel() Extension method

    Gets whether cell_view is configured to request space to fit the entire GtkTreeModel.

    Declaration

    Swift

    @inlinable
func getFitModel() -> Bool
    Show on GitHub
  • getModel() Extension method

    Returns the model for cell_view. If no model is used nil is returned.

    Declaration

    Swift

    @inlinable
func getModel() -> TreeModelRef!
    Show on GitHub
  • setDisplayedRow(path:) Extension method

    Sets the row of the model that is currently displayed by the GtkCellView. If the path is unset, then the contents of the cellview “stick” at their last value; this is not normally a desired result, but may be a needed intermediate state if say, the model for the GtkCellView becomes temporarily empty.

    Declaration

    Swift

    @inlinable
func setDisplayedRow(path: TreePathRef? = nil)
    Show on GitHub
  • setDisplayedRow(path:) Extension method

    Sets the row of the model that is currently displayed by the GtkCellView. If the path is unset, then the contents of the cellview “stick” at their last value; this is not normally a desired result, but may be a needed intermediate state if say, the model for the GtkCellView becomes temporarily empty.

    Declaration

    Swift

    @inlinable
func setDisplayedRow<TreePathT>(path: TreePathT?) where TreePathT : TreePathProtocol
    Show on GitHub
  • set(drawSensitive:) Extension method

    Sets whether cell_view should draw all of its cells in a sensitive state, this is used by GtkComboBox menus to ensure that rows with insensitive cells that contain children appear sensitive in the parent menu item.

    Declaration

    Swift

    @inlinable
func set(drawSensitive: Bool)
    Show on GitHub
  • set(fitModel:) Extension method

    Sets whether cell_view should request space to fit the entire GtkTreeModel.

    This is used by GtkComboBox to ensure that the cell view displayed on the combo box’s button always gets enough space and does not resize when selection changes.

    Declaration

    Swift

    @inlinable
func set(fitModel: Bool)
    Show on GitHub
  • set(model:) Extension method

    Sets the model for cell_view. If cell_view already has a model set, it will remove it before setting the new model. If model is nil, then it will unset the old model.

    Declaration

    Swift

    @inlinable
func set(model: TreeModelRef? = nil)
    Show on GitHub
  • set(model:) Extension method

  • displayedRow Extension method
