TreeStore

open class TreeStore : GLibObject.Object, TreeStoreProtocol

A tree-like data structure that can be used with the GtkTreeView

The GtkTreeStore object is a list model for use with a GtkTreeView widget. It implements the GtkTreeModel interface, and consequently, can use all of the methods available there. It also implements the GtkTreeSortable interface so it can be sorted by the view. Finally, it also implements the tree drag and drop interfaces.

GtkTreeStore as GtkBuildable

The GtkTreeStore implementation of the GtkBuildable interface allows to specify the model columns with a <columns> element that may contain multiple <column> elements, each specifying one model column. The “type” attribute specifies the data type for the column.

An example of a UI Definition fragment for a tree store:

<object class="GtkTreeStore">
  <columns>
    <column type="gchararray"/>
    <column type="gchararray"/>
    <column type="gint"/>
  </columns>
</object>

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

    Declaration

    Swift

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

    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 TreeStore instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
