Return values from uifigure by pressing OK button

Hello

I have a simple form composed of 2 uitextarea and an OK button

How can I tell the form to return the values of the text areas (whatever is inside ) to the workspae or a client function and closing the form after that , more or less like an inputdialog. I am not using the input dialog because I do have two buttons that fill the text areas. A short version follows:

Thanks!!

Julia

function myOutput=test()

mainFig=uifigure;
mainFig.Visible='off';

txt_pos=[30 210 100 40];
txtFile=uitextarea(mainFig,'Position',txt_pos);
txtFile.Editable='on';

txt_pos=[30 150 100 40];
txtCnf=uitextarea(mainFig,'Position',txt_pos);
txtCnf.Editable='on';

btn_pos=[300 50 100 40];
btnOk=uibutton(mainFig,...
          'push',...
          'Position',btn_pos,...
          'ButtonPushedFcn',@(btnOk, event) pushBtOk(btnOk,mainFig,txtCnf,txtFile)); 
       
mainFig.Visible='on';
     

    function pushBtOk(btn,mainfig,txtCnf,txtFile)
        
         disp( txtCnf.Value); 
         disp( txtFile.Value);
         %%put Values into myOutput 
         %%close(uifigure)
 
    end
end
                    

the client code

...
myOutput=test;

if you nest functions in functions, you can directly use the defined variables. note also the uiwait to wait for the functio nreturn until the window was closed

function myOutput=test()

mainFig=uifigure;
mainFig.Visible='off';

txt_pos=[30 210 100 40];
txtFile=uitextarea(mainFig,'Position',txt_pos);
txtFile.Editable='on';

txt_pos=[30 150 100 40];
txtCnf=uitextarea(mainFig,'Position',txt_pos);
txtCnf.Editable='on';

btn_pos=[300 50 100 40];
btnOk=uibutton(mainFig,...
          'push',...
          'Position',btn_pos,...
          'ButtonPushedFcn',@(~, ~) pushBtOk(txtCnf,txtFile)); 
       
mainFig.Visible='on';
     
uiwait(mainFig);
    function pushBtOk(txtCnf,txtFile)
        
         disp( txtCnf.Value); 
         disp( txtFile.Value);

         myOutput(1)=txtCnf.Value;
         myOutput(2)=txtFile.Value;

         %%put Values into myOutput 
         close(mainFig)
 
    end
end
                    

try it using

twoFields=test();

you could even call the function without further arguments

          'ButtonPushedFcn',@(~, ~) pushBtOk()); 

and

          function pushBtOk()
          %....
          end
