TreeViewColumn

open class TreeViewColumn : GLibObject.InitiallyUnowned, TreeViewColumnProtocol

A visible column in a GtkTreeView widget

The GtkTreeViewColumn object represents a visible column in a GtkTreeView widget. It allows to set properties of the column header, and functions as a holding pen for the cell renderers which determine how the data in the column is displayed.

Please refer to the tree widget conceptual overview for an overview of all the objects and data types related to the tree widget and how they work together, and to the GtkTreeView documentation for specifics about the CSS node structure for treeviews and their headers.

The TreeViewColumn type acts as a reference-counted owner of an underlying GtkTreeViewColumn instance. It provides the methods that can operate on this data type through TreeViewColumnProtocol conformance. Use TreeViewColumn as a strong reference or owner of a GtkTreeViewColumn instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the TreeViewColumn instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<GtkTreeViewColumn>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the TreeViewColumn instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<GtkTreeViewColumn>)

    Parameters

    op

    pointer to the underlying object

override public init!(gpointer op: gpointer?)

    Parameters

    op
