Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_uilayout”.

  FT_UILAYOUT is a helper function to make a consistent graphical user interafce with
  multiple control elements. This function will find all elements with a specific tag
  and style, and update or position them consistently.
 
  Use as
    ft_uilayout(h, 'tag', '...', 'style', '...', ...)
  where h is the figure handle and 'tag' and 'style' are used to specifying which
  user control elements in the figure should be selected.
 
  You can pass most options from UICONTROL as key-value pair, such as
  'BackgroundColor', 'CallBack', 'Clipping', 'Enable', 'FontAngle', 'FontName',
  'FontSize', 'FontUnits', 'FontWeight', 'ForegroundColor', 'HorizontalAlignment',
  'Max', 'Min', 'Position', 'Selected', 'String', 'Units', 'Value', 'Visible'.
 
  In addition to the options from UICONTROL, you can use the following key-value
  pairs for a consistent placement of multiple GUI elements relative to each other:
    'hpos'         = 'auto'       puts elements in horizontal adjacent order with a fixed distance of 0.01
                     'align'      adjusts the horizontal position of all elements to the first element
                     'distribute' puts elements in horizontal adjacent order such that they distribute evenly
                     scalar       sets the horizontal position of elements to the specified scalar
    'vpos'         = 'auto'       puts elements in vertical adjacent order with a fixed distance of 0.01
                     'align'      adjusts the vertical position of all elements to the first element
                     'distribute' puts elements in vertical adjacent order such that they distribute evenly
                     scalar       sets the vertical position of elements to the specified scalar
    'width'        = scalar       sets the width of elements to the specified scalar
    'height'       = scalar       sets the height of elements to the specified scalar
    'halign'       = 'left'       aligns the horizontal position of elements to the left
                     'right'      aligns the horizontal position of elements to the right
    'valign'       = 'top'        aligns the vertical position of elements to the top
                     'bottom'     aligns the vertical position of elements to the bottom
    'halign'       = 'left'       aligns the horizontal position of elements to the left
                     'right'      aligns the horizontal position of elements to the right
    'hshift'       = scalar       shift the elements in horizontal direction
    'vshift'       = scalar       shift the elements in vertical direction
 
  Here is an example that positions a number of buttons in a 2x3 grid. It makes use
  of regular expressions to match the tags to the rows and columns.
 
    h = figure;
    uicontrol('style', 'pushbutton', 'string', '11', 'tag', 'row1_column1');
    uicontrol('style', 'pushbutton', 'string', '12', 'tag', 'row1_column2');
    uicontrol('style', 'pushbutton', 'string', '13', 'tag', 'row1_column3');
    uicontrol('style', 'pushbutton', 'string', '21', 'tag', 'row2_column1');
    uicontrol('style', 'pushbutton', 'string', '22', 'tag', 'row2_column2');
    uicontrol('style', 'pushbutton', 'string', '23', 'tag', 'row2_column3');
 
    ft_uilayout(h, 'tag', '^row1', 'vpos', 100);
    ft_uilayout(h, 'tag', '^row2', 'vpos', 200);
 
    ft_uilayout(h, 'tag', 'column1$', 'hpos', 100);
    ft_uilayout(h, 'tag', 'column2$', 'hpos', 200);
    ft_uilayout(h, 'tag', 'column3$', 'hpos', 300);
 
    ft_uilayout(h, 'tag', '.*', 'BackGroundColor', [1 0 0]);
