Removed the drag & drop interfaces, apparently these aren't good enough
2004-01-23 Jeffrey Stedfast <fejj@ximian.com> * em-folder-tree-model.c (em_folder_tree_model_get_type): Removed the drag & drop interfaces, apparently these aren't good enough for what we need. Gotta implement this all the Hard Way (tm). (em_folder_tree_model_drag_data_received): Helper function called by the drag_data_received signal callback in em-folder-tree.c (em_folder_tree_model_row_drop_possible): Same idea. (em_folder_tree_model_row_drop_target): Again. (em_folder_tree_model_row_draggable): You get the idea... (em_folder_tree_model_drag_data_get): And again. (em_folder_tree_model_drag_data_delete): Same. (em_folder_tree_model_set_drag_drop_types): Setup the drag & drop types on the widget (since the target drag & drop types are now internal to the model code rathr than the tree code). * em-folder-tree.c (em_folder_tree_enable_drag_and_drop): Rewritten. Connect to all the drag & drop signals and implemnent them. svn path=/trunk/; revision=24393
