Member Function Documentation

editor_action_paste * editor::editor_action_paste::clone ( ) const

virtual

Action cloning.

Implements editor::editor_action.

Definition at line 158 of file action.cpp.

References editor_action_paste().

void editor::editor_action_paste::extend	(	const editor_map &	map,
		const std::set< map_location > &	locs
	)

virtual

The crux of the extendable contract.

This member function must be implemented so that the undo behavior is consistent, exactly the same as would be with separate undo actions for every part of the drag.

Implements editor::editor_action_extendable.

Definition at line 162 of file action.cpp.

const char* editor::editor_action_paste::get_name ( ) const

inlinevirtual

Returns: a short name of this action type, defaults to unknown

Reimplemented from editor::editor_action_extendable.

Definition at line 235 of file action.hpp.

editor_action_paste * editor::editor_action_paste::perform ( map_context & mc ) const

virtual

Perform the action, returning an undo action that, when performed, shall reverse any effects of this action.

The undo action object is owned by the caller. Default behavior is to create a whole-map undo, call the perform_without_undo function and return the undo object.

Reimplemented from editor::editor_action.
