TreeDragSourceProtocol

public protocol TreeDragSourceProtocol

The TreeDragSourceProtocol protocol exposes the methods and properties of an underlying GtkTreeDragSource 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 TreeDragSource. Alternatively, use TreeDragSourceRef as a lighweight, unowned reference if you already have an instance you just want to use.

  • ptr

    Untyped pointer to the underlying GtkTreeDragSource instance.

  • tree_drag_source_ptr Default implementation

    Typed pointer to the underlying GtkTreeDragSource instance.

    Default Implementation

    Return the stored, untyped pointer as a typed pointer to the GtkTreeDragSource instance.

    Declaration

    Swift

    var tree_drag_source_ptr: UnsafeMutablePointer<GtkTreeDragSource>! { get }

TreeDragSource Interface: TreeDragSourceProtocol extension (methods and fields)

  • dragDataDelete(path:) Extension method

    Asks the GtkTreeDragSource to delete the row at path, because it was moved somewhere else via drag-and-drop. Returns false if the deletion fails because path no longer exists, or for some model-specific reason. Should robustly handle a path no longer found in the model!

    Declaration

    Swift

    @inlinable
func dragDataDelete<TreePathT>(path: TreePathT) -> Bool where TreePathT : TreePathProtocol
    Show on GitHub

  • Asks the GtkTreeDragSource to fill in selection_data with a representation of the row at path. selection_data->target gives the required type of the data. Should robustly handle a path no longer found in the model!

    Declaration

    Swift

    @inlinable
func dragDataGet<SelectionDataT, TreePathT>(path: TreePathT, selectionData: SelectionDataT) -> Bool where SelectionDataT : SelectionDataProtocol, TreePathT : TreePathProtocol
    Show on GitHub
  • rowDraggable(path:) Extension method

    Asks the GtkTreeDragSource whether a particular row can be used as the source of a DND operation. If the source doesn’t implement this interface, the row is assumed draggable.

    Declaration

    Swift

    @inlinable
func rowDraggable<TreePathT>(path: TreePathT) -> Bool where TreePathT : TreePathProtocol
