1 function [mtable, buttons] = createTable(pnContainer,headers,data,buttonsFlag,varargin)
2 % createTable - create nice-looking table based on javax.swing.JTable
3 %
4 % Syntax:
5 % [mtable, buttons] = createTable (pnContainer, headers, data, buttonsFlag, 'PropName',PropValue, ...)
6 %
7 % Input Parameters:
8 % pnContainer - optional handle to container uipanel or figure. If empty/unsupplied then current figure will be used
9 % headers - optional cell array of column header strings. If unsupplied then = {'A','B','C'}
10 % data - optional vector/matrix (either scalar or cell array) of data values
11 % buttonsFlag - optional flag indicating whether to create the table-manipulation buttons. Default = true
12 % 'PropName',PropValue -
13 % optional list of property pairs (e.g., 'AutoResizeMode',4,'Editable',false,'Position',[.1,.1,.5,.5])
14 % Note: PropName must be either an mtable property ('Visible','Editable','Position','Units',
15 % 'DataChangedCallback',...) or otherwise a Javax.swing.JTable property ('ShowGrid','Name',...).
16 % Abbreviated PropNames are unsupported for mtable properties (which are few) - only for JTable
17 %
18 % Output parameters:
19 % mtable - handle to mtable object (a Matlab object)
20 % buttons - handles to table manipulation buttons: [<appendRow> <insertRow> <deleteRow> <deleteAll> <printAll>]
21 %
22 % Examples:
23 % [mtable, buttons] = createTable;
24 % [mtable, buttons] = createTable(gcf,'column name');
25 % mtable = createTable([],{'a','b','c','d'},{false,1.3,uint16(45),'ert'; true,pi,uint16(-4),'defrgt'})
26 % mtable = createTable([],{'a','b','c','d'},magic(4),false,'AutoResizeMode',javax.swing.JTable.AUTO_RESIZE_ALL_COLUMNS)
27 % mtable = createTable([],{'rads','sin','cos'},[pi,sin(pi),cos(pi)],'SelectionMode',javax.swing.ListSelectionModel.SINGLE_INTERVAL_SELECTION)
28 %
29 % Usage:
30 % The table automatically resizes to fill the pnContainer (you may modify this via the 'Position' property).
31 % The table automatically sets the columns' cell editor and renderer based on the supplied data. Logical values are
32 % given a checkbox, strings are left-aligned (numbers are right-aligned). You can always override the defaults.
33 % You can change column widths by dragging the column borders on the header row.
34 % You can sort columns by clicking the column header (once to sort descending, once again to sort ascending and once
35 % more for the unsorted view). Sorting multiple columns is done by control-clicking all relevant columns (the
36 % sorting icon is decreased in size for each additional minor sort col).
37 % You can copy/paste any consecutive region of table cells, just as in Excel. You can select entire rows or columns
38 % by right-clicking their header. You can also paste Excel data directly, with Ctrl-Shift-V (or use the context
39 % menu by right-clicking) at the target table cell.
40 % For additional tips about how to set multiple aspects of the table, refer to:

43 % Programming tips/cues/examples:
44 % mtable = creatTable(...)
45 % jtable = mtable.getTable;
46 % mtable.setVisible(false);
47 % mtable.setCheckBoxEditor(1); % Set first column to a checkbox (see Note 2 below)
48 % cb = javax.swing.JComboBox({'First','Last'}); cb.setEditable(true); % prepare an editable drop-down CellEditor
49 % editor = javax.swing.DefaultCellEditor(cb);
50 % jtable.getColumnModel.getColumn(1).setCellEditor(editor); % assign this editor to second column (see Note 2)
51 % jtable.getColumnModel.getColumn(0).setMaxWidth(20); % Limit width of first (checkbox) column (see Note 2)
52 % mtable.setEditable(0,false); % Disable editing first column (see note 2 below)
53 % renderer = javax.swing.table.DefaultTableCellRenderer; % or: renderer = jtable.getColumnModel.getColumn(1).getCellRenderer
54 % renderer.setHorizontalAlignment(javax.swing.SwingConstants.RIGHT); % useful for numbers rendered as strings e.g.: jtable.setValueAt(sprintf('%.1f',pi,rowIdx,colIdx))
55 % jtable.getColumnModel.getColumn(1).setCellRenderer(renderer); % right-align second column (see note 2)
56 % data = cell(mtable.getData); % a cell matrix (mtable.getData is a java.lang.Object[][] object, using base-1 indexing)
57 % data = mtable.getTableModel.getDataVector; % a java.util.Vector object ([[false, 1.3, 45, ert], [true, 3.14,...]])
58 % jtable.setValueAt(value,rowIdx,colIdx); % 0-based Idx - see Note 2 below
59 % jtable.getModel.addRow({true, pi, int16(45), 'test'}); % appends a row to the bottom of the table
60 % mtable.DataChangedCallback = []; % used to temporarily disable data-change callbacks
61 % mtable.DataChangedCallback = @myDataChange_Callback; % myDataChange_Callback is a Matlab function
62 %
63 % % Sample dataChange_Callback function
64 % function dataChange_Callback(mtable, eventdata)
65 % if ~ishandle(mtable), return; end
66 % % Prevent re-entry here if the callback is not thread-safe - see Note 3 below
67 % eventDetails = eventdata.getEvent;
68 % modifiedColIdx = eventDetails.getColumn;
69 % modifiedRowIdx = eventDetails.getFirstRow;
70 % if modifiedColIdx>=0 && modifiedRowIdx>=0
71 % data = mtable.getData;
72 % newValue = data(modifiedRowIdx+1,modifiedColIdx+1); % see Note 2 below
73 % switch modifiedColIdx
74 % case ...
75 % end
76 % end
77 %
78 % Notes:
79 % 1. Some (very few) JTable features are inconsistent or unavailable in different jave versions. Type
80 % '<a href="matlab:version -java">version -java</a>' at the command prompt to see your specific java version.
81 % 2. Note that java uses 0-based indexing, while Matlab is 1-based. The returned mtable parameter is a Matlab object
82 % (so use 1-base), while mtable.getXXX returns java objects (0-based). jtable above is an example of a java object.
83 % 3. Modifying mtable.DataChangedCallback within the callback doesn't work - you need to use some global flag/mutex
84 % 4. The <Print> button uses Excel to parse and print the table
85 % 5. Due to Matlab limitations (specifically, of uitable/UitablePeer) the table is created as a direct child of
86 % the container figure (although it is visually positioned within pnContainer)
87 % 6. To enable sorting functionality, the attached TableSorter.jar file must be located in the java classpath.
88 % See the Matlab documentation for <a href="matlab:doc javaclasspath">javaclasspath</a>. Note that using
89 % javaaddpath(...) to set the path has a nasty side-effect (at least since Matlab 7.2) of clearing all globals!
90 % An alternative is to place the pathname for TableSorter.jar in the <a href="matlab:which classpath.txt">classpath.txt</a> file
91 %
92 % Known issues/limitations:
93 % - Column alignment not preserved during Print
94 % - Print fails if Excel unavailable (maybe directly print tab-separated text data)
95 % - Unable to add/delete rows or to print via context menu (right-click)
96 % - Table is created as a direct child of figure, not pnContainer (see Note 5 above)
