Methods

• TreeDragSource (Handle = null)

  Creates a new TreeDragSource by wrapping a native handle or another wrapper.

  • @p Handle is the native handle or another wrapper whose handle to adopt.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• drag_data_delete (object path)

  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!

  • @p path is row that was being dragged.

• drag_data_get (object path)

  Asks the GtkTreeDragSource to return a GdkContentProvider representing the row at @path. Should robustly handle a @path no longer found in the model!

  • @p path is row that was dragged.

• row_draggable (object path)

  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.

  • @p path is row on which user is initiating a drag.
