function varargout = stateflowalign(varargin)
% STATEFLOWALIGN M-file for stateflowalign.fig
%      STATEFLOWALIGN, by itself, creates a new STATEFLOWALIGN or raises the existing
%      singleton*.
%
%      H = STATEFLOWALIGN returns the handle to a new STATEFLOWALIGN or the handle to
%      the existing singleton*.
%
%      STATEFLOWALIGN('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in STATEFLOWALIGN.M with the given input arguments.
%
%      STATEFLOWALIGN('Property','Value',...) creates a new STATEFLOWALIGN or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before stateflowalign_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to stateflowalign_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

%
% stateflow align implements three basic functions to align and modify
% graphical stateflow objects:
% 1. Align
%   All selected objects are aligned to the last object in the selection.
%   Therefore at least two objects must be selected. Alignment is done to
%   specific alignment lines. These are left, rigth, top, bottom,
%   horizontal centre and vertical centre for rectangular graphical objects
%   and the centre of junctions.
% 2. Copy Size
%   The size of the last selected object is copied to all other selected
%   objects. This function works only on rectangular objects.
% 3. Distance
%   Bring the selected objects to a specified distance relating to their
%   bounds in x or y direction. In the auto mode the direction of the
%   higher misalignment is used.
%   In non cascaded submode the last selected object is the reference.
%   In cascaded submode the n-th object is the reference of the (n-1)th
%       object. The process starts with the last selected element as first
%       reference.
% REMARKS:
% 1. To select multiple objects hold down the shift key while mouse
% clicking the objets.
% 2. Transitions should not be selected since they loose their connection.
% 3. There is NO UNDO possibility because the stateflow API is unsed. Save
% the file before using this tool!!
