function [selection,value] = choosebox(varargin)
%CHOOSEBOX  Two-listed item selection dialog box.
%   [SELECTION,OK] = CHOOSEBOX('ListString',S) creates a modal dialog box 
%   which allows you to select a string or multiple strings from a list.
%   Single or multiple strings can be transferred from a base list to a
%   selection list using an arrow-button. Single strings also can be
%   transferred by double-clicking; single or multiple strings are
%   transferred by pressing <CR>.
%   SELECTION is a vector of indices of the selected strings (length 1
%   in the single selection mode). The indices will be in the order of
%   selection from the base list. If a group of multiple strings is
%   selected, its order inside the group will not change, but different
%   groups are ordered by their selection. 
%   OK is 1 if you push the OK button, or 0 if you push the Cancel 
%   button or close the figure. In that case SELECTION will be [],
%   regardless to the actual selection list.
%   Important parameter is 'ChooseMode', see list below.
%
%   Inputs are in parameter,value pairs:
%
%   Parameter       Description
%   'ChooseMode'    string; can be 'pick' or 'copy'.
%                   When set to 'pick', transferred string items from the
%                   base list box are removed. When retransferred, they
%                   again are listed in their initial positions.
%                   When set to 'copy', transferred string items remain in
%                   the base list and can be transferred several times.
%                   default is 'pick'.
%   'ListString'    cell array of strings for the base list box.
%   'SelectionMode' string; can be 'single' or 'multiple'; defaults to
%                   'multiple'.
%   'ListSize'      [width height] of listbox in pixels; defaults
%                   to [160 300].
%   'InitialValue'  vector of indices of which items of the list box
%                   are initially selected; defaults to none [].
%   'Name'          String for the figure's title. Defaults to ''.
%   'PromptString'  string matrix or cell array of strings which appears 
%                   as text above the base list box.  Defaults to {}.
%   'SelectString'  string matrix or cell array of strings which appears
%                   as text above the selection list box. Defaults to {}.
%   'OKString'      string for the OK button; defaults to 'OK'.
%   'CancelString'  string for the Cancel button; defaults to 'Cancel'.
%   'uh'            uicontrol button height, in pixels; default = 18.
%   'fus'           frame/uicontrol spacing, in pixels; default = 8.
%   'ffs'           frame/figure spacing, in pixels; default = 8.
%
%   Example:
%     d = dir;
%     str = {d.name};
%     [s,v] = choosebox('Name','File deletion',...
%                     'PromptString','Files remaining in this directory:',...
%                     'SelectString','Files to delete:',...
%                     'ListString',str)
