deferred class EV_PICK_AND_DROPABLE General cluster: interface description: "Facilities for pick and drop mechanism. Decendents can act both as pick and drop sources and as targets. When the user picks a pebble from a source and drops on a target,the drop_actions of the target receive the pebble as input. The user interface can be either pick and drop or drag and drop,selected by set_pick_and_drop and set_drag_and_drop." keywords: "pick and drop, drag and drop, source, PND, DND" Ancestors EV_ABSTRACT_PICK_AND_DROPABLE* EV_ANY* EV_PICK_AND_DROPABLE_ACTION_SEQUENCES* EV_POSITIONED* Action sequences conforming_pick_actions: EV_NOTIFY_ACTION_SEQUENCE drop_actions: EV_PND_ACTION_SEQUENCE pick_actions: EV_PND_START_ACTION_SEQUENCE pick_ended_actions: EV_PND_FINISHED_ACTION_SEQUENCE pointer_motion_actions: EV_POINTER_MOTION_ACTION_SEQUENCE Queries accept_cursor: EV_POINTER_STYLE configurable_target_menu_handler: detachable PROCEDURE [EV_MENU, ARRAYED_LIST [EV_PND_TARGET_DATA], EV_PICK_AND_DROPABLE, detachable ANY] data: detachable ANY deny_cursor: EV_POINTER_STYLE height: INTEGER_32 id_object (an_id: INTEGER_32): detachable IDENTIFIED is_destroyed: BOOLEAN minimum_height: INTEGER_32 minimum_width: INTEGER_32 mode_is_configurable_target_menu: BOOLEAN mode_is_drag_and_drop: BOOLEAN mode_is_pick_and_drop: BOOLEAN mode_is_target_menu: BOOLEAN object_id: INTEGER_32 pebble: detachable ANY pebble_function: detachable FUNCTION [detachable ANY] pebble_positioning_enabled: BOOLEAN pebble_x_position: INTEGER_32 pebble_y_position: INTEGER_32 screen_x: INTEGER_32 screen_y: INTEGER_32 target_data_function: detachable FUNCTION [[like pebble] detachable ANY, EV_PND_TARGET_DATA] target_name: detachable READABLE_STRING_GENERAL width: INTEGER_32 x_position: INTEGER_32 y_position: INTEGER_32 Commands copy (other: [like Current] EV_PICK_AND_DROPABLE) destroy disable_pebble_positioning enable_pebble_positioning remove_pebble set_accept_cursor (a_cursor: [detachable like accept_cursor] detachable EV_POINTER_STYLE) set_configurable_target_menu_handler (a_handler: detachable PROCEDURE [EV_MENU, ARRAYED_LIST [EV_PND_TARGET_DATA], EV_PICK_AND_DROPABLE, detachable ANY]) set_configurable_target_menu_mode set_data (some_data: [like data] detachable ANY) set_deny_cursor (a_cursor: [detachable like deny_cursor] detachable EV_POINTER_STYLE) set_drag_and_drop_mode set_pebble (a_pebble: ANY) set_pebble_function (a_function: FUNCTION [detachable ANY]) set_pebble_position (a_x, a_y: INTEGER_32) set_pick_and_drop_mode set_target_data_function (a_function: FUNCTION [[like pebble] detachable ANY, EV_PND_TARGET_DATA]) set_target_menu_mode set_target_name (a_name: READABLE_STRING_GENERAL) show_configurable_target_menu (a_x, a_y: INTEGER_32) Constraints user interface modes mutually exclusive
