MATLAB: Display a Table in GUIDE

guiguideMATLABtableuitable

I'm working on a project and I have to create an interface which contains a table of data previously filled in another interface.

I want to display it in a figure I've created using GUIDE, in a uitable with the tag 'table'.

function s_OpeningFcn(hObject, eventdata, handles, varargin)
% Choose default command line output for select_tron
handles.output = hObject;
movegui('center');
U = getappdata(0,'U');
Tab = struct2table(U.tab,'AsArray',true);
set(handles.table,'Data',Tab);
% Update handles structure
guidata(hObject, handles);

I tried with handles.table.Data=Tab; but it doesn't work neither.

And with uitable(gcf,'Data',Tab)

I get this error :

Error using matlab.ui.control.Table/set
Functionality not supported with figures created with the figure function. For more information, see Graphics Support in App
Designer.
Error in select_tron>select_tron_OpeningFcn (line 99)

uitable only supports setting Data to a table() if the uitable is a child of a uifigure(), rather than the child of a figure()

MATLAB: How can we change the default size table in GUIDE

Shil - in the OpeningFcn of your GUI, just set the Data property of the uitable to be a 2x2 cell array. Something like the following should work

 % --- Executes just before untitled is made visible.
function myGUI_OpeningFcn(hObject, eventdata, handles, varargin)
% Choose default command line output for untitled
handles.output = hObject;
% Update handles structure
guidata(hObject, handles);
% set the table size to be 2x2
set(handles.uitable1,'Data',cell(2,2));

The above was tested with R2014a.

MATLAB: How to find value of modifier with keypressfcn

Lyn - look closely at your if/elseif

 if strcmp(eventdata.Key,'tab')
    handles.a = handles.a + 1
 elseif strcmp(eventdata.Modifier{:},'shift') && strcmp(eventdata.Key,'tab')
    handles.a = handles.a - 1
 end

For your elseif there are two conditions:

 strcmp(eventdata.Modifier{:},'shift') && strcmp(eventdata.Key,'tab')

So the code will decrement a by one if both conditions are true. BUT, the second condition is the (only) condition for the if statement! So your elseif will never evaluate because the if will always take precedence.

Try the following instead

 if strcmp(eventdata.Key,'tab')
    if isempty(eventdata.Modifier)
        handles.a = handles.a + 1
    elseif strcmp(eventdata.Modifier{:},'shift') 
        handles.a = handles.a - 1
    end
 end

Try the above and see what happens! Note that you can remove the line

 handles = guidata(hObject);

and just use the handles structure that is passed as the third input to this function.
