gui wait and gui function output

Hi everyone,

I am struggling for some time now on an issue that appears simple.

I do not manage to wait the ouput of a gui called as a function. I am looking to reproduce something that looks like uigetfile (bloomberg download in my case), but I was not able to understand how they do it.

Windows tyle is modal.

Code pseudo example:

function master_gui    

    S.Fig=figure('callback',@function_xxx);

        function function_xxx(~,~,S)
           [output]= gui_that_load_bloomberg_data()
           % wait something??
            This_should_not_be_one_before_having_a_nice_output=1;
        end
  end

================== on another M file

function [output]= gui_that_load_bloomberg_data()

But.PushLoadEx = uicontrol('style','pushbutton','callback',@LoadExisting);

   function LoadExisting(~,~,~)
     [output] = Stuff_Loaded;  %that line then should start again the master gui
   end
end

Thank you in advance

Are you looking for uiwait, or waitfor?

doc waitfor
doc uiwait

Well, uiwait did the trick perfectly, I was convinced that it did not work before.

An answer such as: "try harder" would have been accepted too...

Thank you.
