Standalone GUI application gives error at uigetfile. But if run from matlab, the script works fine

• MATLAB Version: 9.7.0.1140744 (R2019b) Prerelease
• MATLAB License Number: Prerelease
• Operating System: Microsoft Windows 10 Pro Version 10.0 (Build 18362)
• Java Version: Java 1.8.0_202-b08 with Oracle Corporation Java HotSpot(TM) 64-Bit Server VM mixed mode

Hi all,

This is regarding a TI mmWave application (mmwave_industrial_toolbox_3_6_2\labs\lab0013_traffic_monitoring_16xx\gui) . The script when run from matlab works as expected. But when the App is compiled to a standalone, these errors appear. Note that I have put some fprintf()'s here and there.

How can I fix this?

Any guidance would be much appreciated. Please do not ask me to post this in TI's e2e because they said me to post it here.

I will put the pushbuttonBrowse_Callback here,

% --- Executes on button press in pushbuttonBrowse.
function pushbuttonBrowse_Callback(hObject, eventdata, handles)
% hObject    handle to pushbuttonBrowse (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% Select Chirp Config File
fprintf('== Came to the pushbuttonBrowse_Callback  ==\n');
[filename, pathname] = I will('*.cfg','Pick a Chirp file');
fprintf('== Came to the a ==\n');
configurationFileName = [pathname filename];
fprintf('== Came to the a ==\n');
handles.cfg.filename = configurationFileName;
fprintf('== Came to the c ==\n');

if (filename ~= 0)
    % Read Chirp Configuration file
    cliCfg = readCfg(handles.cfg.filename);
    [Params cliCfg] = parseCfg(cliCfg); 
    
    % Display chirp table
    hTable = findobj('Tag', 'uitableChirp');
    hTable = displayChirpParams(Params, hTable);
    hGtrackTable = findobj('Tag', 'uitableGtrackParams');
    
    % Update handles
    handles.cfg.cliCfg = cliCfg;
    handles.params = Params;
    guidata(hObject,handles)
    
    % Display gtrack params
    % check if params set in CLI commands
    if(isfield(Params, 'gtrackAdvanced'))
        if(isfield(Params.gtrackAdvanced,'sceneryParam'))
            temp = Params.gtrackAdvanced.sceneryParam;
            temp =[reshape(temp(3:10),4,2)'; reshape(temp(12:19),4,2)'];
            temp = cellfun(@str2num,temp);
            hTable = findobj('Tag', 'uitableScenery');
            displayGtrackParams(temp, hTable);
            data = hTable.Data;
            handles.box.boundaryBox = data(1:2,:);%cellfun(@str2num,data(1:2,:));
            handles.box.staticBox = data(3:4,:); %cellfun(@str2num,data(3:4,:));
            handles.box.numBoundary = sum(any(handles.box.boundaryBox,2));
            handles.box.numStatic = sum(any(handles.box.staticBox,2));
            guidata(hObject,handles)
            drawRadarRoom(handles);
        end
        
        if(isfield(Params.gtrackAdvanced,'allocationParam'))
            displayGtrackParams(Params.gtrackAdvanced.allocationParam, findobj('Tag', 'uitableAllocation'));
        end

            displayGtrackParams(Params.gtrackAdvanced.stateParam, findobj('Tag', 'uitableState'));
        end

Looks like you have an incorrect function name. What is "I will" supposed to be?

fprintf('== Came to the pushbuttonBrowse_Callback  ==\n');
[filename, pathname] = I will('*.cfg','Pick a Chirp file');

If you have the 19b prerelease, I assume you also have 19a. What happens when you create a standalone app using 19a instead? Do you get the same error messages?

[Cris LaPierre]

I was able to test it in 19a. It worked there. I made a simple gui in 19b prerelease that just is a pushbutton with uigetfile and that also does not work. I don't get the error messages you see, but uigetfile doesn't launch.

I'll provide feedback internally.

If you have a chance, you might also want to report this issue to Customer Support.
