TreeStoreProtocol

public protocol TreeStoreProtocol : ObjectProtocol, BuildableProtocol, TreeDragDestProtocol, TreeDragSourceProtocol, TreeSortableProtocol

The GtkTreeStore object is a list model for use with a GtkTreeView widget. It implements the GtkTreeModel interface, and consequentially, 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 TreeStoreProtocol protocol exposes the methods and properties of an underlying GtkTreeStore 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 TreeStore. Alternatively, use TreeStoreRef as a lighweight, unowned reference if you already have an instance you just want to use.

TreeStore Class: TreeStoreProtocol extension (methods and fields)

  • append(iter:parent:) Extension method

    Appends a new row to tree_store. If parent is non-nil, then it will append the new row after the last child of parent, otherwise it will append a row to the top level. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_tree_store_set() or gtk_tree_store_set_value().

    Declaration

  • clear() Extension method

    Removes all rows from tree_store

    Declaration

    Swift

    @inlinable
func clear()
    Show on GitHub

  • Creates a new row at position. If parent is non-nil, then the row will be made a child of parent. Otherwise, the row will be created at the toplevel. If position is -1 or is larger than the number of rows at that level, then the new row will be inserted to the end of the list. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_tree_store_set() or gtk_tree_store_set_value().

    Declaration

    Swift

    @inlinable
func insert<TreeIterT>(iter: TreeIterT, parent: TreeIterT?, position: Int) where TreeIterT : TreeIterProtocol
    Show on GitHub

  • Inserts a new row after sibling. If sibling is nil, then the row will be prepended to parent ’s children. If parent and sibling are nil, then the row will be prepended to the toplevel. If both sibling and parent are set, then parent must be the parent of sibling. When sibling is set, parent is optional.

    iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_tree_store_set() or gtk_tree_store_set_value().

    Declaration

    Swift

func insertAfter<TreeIterT>(iter: TreeIterT, parent: TreeIterT?, sibling: TreeIterT?) where TreeIterT : TreeIterProtocol
    Show on GitHub

  • Inserts a new row before sibling. If sibling is nil, then the row will be appended to parent ’s children. If parent and sibling are nil, then the row will be appended to the toplevel. If both sibling and parent are set, then parent must be the parent of sibling. When sibling is set, parent is optional.

    iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_tree_store_set() or gtk_tree_store_set_value().
