				bool toggle() const; ///< Gets the tool toggle state (only if tool style is toggle).
				item_proxy& toggle(bool toggle_state); ///< Sets the tool toggle state (only if tool style is toggle).
				std::string toggle_group() const;	///< Returns the toggle group associated with the tool (only if tool style is toggle).
				item_proxy& toggle_group(const ::std::string& group);	///< Adds the tool to a toggle group (only if tool style is toggle).
