rb_tree_drag_source_row_draggable ()

gboolean
rb_tree_drag_source_row_draggable (RbTreeDragSource *drag_source,
                                   GList *path_list);

Asks the RbTreeDragSource 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.

rb_tree_drag_source_drag_data_delete ()

gboolean
rb_tree_drag_source_drag_data_delete (RbTreeDragSource *drag_source,
                                      GList *path_list);

Asks the RbTreeDragSource 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!

rb_tree_drag_source_drag_data_get ()

gboolean
rb_tree_drag_source_drag_data_get (RbTreeDragSource *drag_source,
                                   GList *path_list,
                                   GtkSelectionData *selection_data);

Asks the RbTreeDragSource 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!

rb_tree_drag_dest_drag_data_received ()

gboolean
rb_tree_drag_dest_drag_data_received (RbTreeDragDest *drag_dest,
                                      GtkTreePath *dest,
                                      GtkTreeViewDropPosition pos,
                                      GtkSelectionData *selection_data);

Asks a RbTreeDragDest to accept some drag and drop data.

rb_tree_drag_dest_row_drop_possible ()

gboolean
rb_tree_drag_dest_row_drop_possible (RbTreeDragDest *drag_dest,
                                     GtkTreePath *dest_path,
                                     GtkTreeViewDropPosition pos,
                                     GtkSelectionData *selection_data);

Asks the RbTreeDragDest whether data can be dropped on a particular row. This should probably check based on the format and the row.

rb_tree_drag_dest_row_drop_position ()

gboolean
rb_tree_drag_dest_row_drop_position (RbTreeDragDest *drag_dest,
                                     GtkTreePath *dest_path,
                                     GList *targets,
                                     GtkTreeViewDropPosition *pos);

Asks the RbTreeDragDest which drop position to use relative to the specified row. The drag destination should decide which drop position to use based on the target row and the list of drag targets.

rb_tree_dnd_add_drag_dest_support ()

void
rb_tree_dnd_add_drag_dest_support (GtkTreeView *tree_view,
                                   RbTreeDestFlag flags,
                                   const GtkTargetEntry *targets,
                                   gint n_targets,
                                   GdkDragAction actions);

Adds event handlers to perform multi-row drag and drop operations to the specified GtkTreeView. The model backing the tree view should implement the RbTreeDragDest interface. This should be called immediately after the tree view is created.

rb_tree_dnd_add_drag_source_support ()

void
rb_tree_dnd_add_drag_source_support (GtkTreeView *tree_view,
                                     GdkModifierType start_button_mask,
                                     const GtkTargetEntry *targets,
                                     gint n_targets,
                                     GdkDragAction actions);

Adds event handlers to perform multi-row drag and drop operations from the specified GtkTreeView widget. The model backing the GtkTreeView must implement the RbTreeDragSource interface. This should be called immediately after the tree view is created.
