Hello,

I'm trying to create a GUI for Model In loop Regression testing using the Matlab script. Here I have 100 testcases,

I want to select single testcase out of 100 and that selected testcase should run. I want the format to look like below

Testcase 1

(i)TestCase1a

(ii)TestCase2a

2. TestCase 2

(i)TestCase1b

(ii)TestCse2b

etc

Currently, I'm using prompt command to enter the Testcase number I want to run. But I want to improvise this in GUI format which has all the testcases for the user selection.

Any inputs greatly appreciated!

Thank you!

You're welcome!

Here is a code structure you can use (you should take care that only one node is selected at a time, too):

function TreeSelectionChanged(app, event)
    switch app.Tree.SelectedNodes
        case app.Sensor1FaultNode % <- the name of Sensor1 Fault Node in your app
            TC_RunNum = 10;
        case app.Sensor2FaultNode % <- the name of Sensor2 Fault Node in your app
            TC_RunNum = 11;
        % etc.
    end
    % then run your script here
end

I have added the switch cases in the mlapp file

I tried to call this mlapp file from .m script by running

run("app1.mlapp");

Looks like it is not running that command and going through the other lines of the .m script. Below is the .m script(just initial couple of lines)

clc;

run("app1.mlapp");

TC_size = size(TC_data);

TC_row = TC_size(1);

TC_len = length(TC_data(:,TC_RunNum).Variables);

After running the above lines, it throughs the below error:

Unrecognized function or variable 'TC_RunNum'.

Error in RunSelectTC (line 40)

TC_len = length(TC_data(:,TC_RunNum).Variables);

I have mentioned the TC_RunNum in the .mlapp file like below

methods (Access = private)

% Selection changed function: Tree

function TreeSelectionChanged(app, event)

switch app.Tree.SelectedNodes

case app.FNRFltNode

TC_RunNum = 25;

case app.StrFltNode %

TC_RunNum = 28;

case app.PrkbrkswfltNode

TC_RunNum = 40;

case app.PBSolfltNode

TC_RunNum = 41;

end

Quesions:

How to call the mlapp file in the .m script? so that user can select the testcase.
The mlapp file which I'm creating is only for the testcase selection. Once the user selects the testcase, it should come back to the .m script. Should I add any logic over here in the mlapp script to go back to .m script? Or something to do add in the m script?

Thank you!!

get_case_number.m

I misunderstood the situation before; I thought you were running a script from an app, not the other way around.

If all you need is a single selection to set a variable in your script, you can run a simple GUI (not an app) from your script. Something like this would work. Here I'm using a popupmenu, but you could use a uitree.

function out = get_case_number()
f = figure( ...
    'NumberTitle','off', ...
    'IntegerHandle','off', ...
    'HandleVisibility','off', ...
    'Name','Select Case', ...
    'Menubar','none', ...
    'Toolbar','none', ...
    'Units','pixels', ...
    'Position',[300 400 200 140]);
p = uicontrol(f, ...
    'Style','popupmenu', ...
    'String',{'FNRFlt';'StrFlt';'Prkbrkswflt';'PBSolflt'}, ... % specify the case names
    'UserData',[25;28;40;41], ...                              % and corresponding TC_RunNum value
    'Value',1, ...
    'Units','pixels', ...
    'Position',[20 100 80 22]);
b = uicontrol(f, ...
    'Style','pushbutton', ...
    'String','Select', ...
    'Units','pixels', ...
    'Position',[30 20 65 22], ...
    'Callback',@cb_button);
out = [];
uiwait(f);
    function cb_button(~,~)
        UD = get(p,'UserData');
        out = UD(get(p,'Value'));
        delete(f);
    end
end

Then in your script, at the point where the user should make a selection, just say:

TC_RunNum = get_case_number();

and continue with the rest of the script, e.g.:

TC_size = size(TC_data);
TC_row = TC_size(1);
TC_RunNum = get_case_number();
TC_len = length(TC_data(:,TC_RunNum).Variables);

Hello,

I tried to add listbox instead of popup menu. But how to add the dropdown within the same uicontrol? Like for some cases I need to have dropdown and for some cases no need.

I have added the uidropdown below:

function out = get_case_number()
f = figure( ...
    'NumberTitle','off',...
    'IntegerHandle','off', ...
    'HandleVisibility','off', ...
    'Name','Select TestCase', ...
    'Menubar','none', ...
    'Toolbar','none', ...
    'Units','pixels', ...
    'Position',[300 200 200 140]);
p = uicontrol(f, ...
    'Style','listbox', ...
    'String',{'sensr1flt';'sensr2flt';'sensr3flt';'sensr4flt'}, ... % specify the case names
    'UserData',[25;28;40;41], ...                              % and corresponding TC_RunNum value
    'Value',1, ...
    'Units','pixels', ...
    'Position',[20 100 80 60]);
a = uidropdown(f,"Items",["sensr1flt","sensr2flt","sensr3flt","sensr4flt"], ...
    'UserData',[21;22;23;24], ...
    'Position',[20 100 80 60]);

It is giving the below error:

Error using uidropdown (line 41)

Functionality not supported with figures created with the figure function.

Error in get_case_number (line 22)

a = uidropdown(f,"Items",["sensr1flt","sensr2flt","sensr3flt","sensr4flt"], ...

It is not allowing me to use the same figure. Looks like I have to use dropdown within the same uicontrol ,How to use the dropdown within the same uicontrol?

Thank you

get_case_number.m

See the attached modifed m-file.

You need the uiwait in order to be able to return the selected value. But also the button needs a callback, which was missing for uibutton. I put that in place.

Also, Value means different things for a uicontrol button vs a uibutton (as described in the links I posted earlier), so I fixed the button callback to work for a uibutton.

I also repositioned the objects to have a reasonable initial arrangement.
