Transfer of information between GUIs

Hi everyone,

I'm working on a program which have 2 GUIs. My GUI_A is my main GUI and GUI_B is the sub GUI.

I have a PushButton in my GUI_B and I want to know in my GUI_A when this pushbutton has been activate. Do you know a way to do it?

My code in GUI_A :

handles.GUI_B=GUI_B; %Open GUI_B
handles.GUI_B=guidata(findall(0,'Tag','GUI_B)); %retrieve handles from GUI_B
while get(handles.GUI_B.PushButton,'Value')~=1
    handles.GUI_B=guidata(findall(0,'Tag','GUI_B)); %Update Handles from GUI_B
end
close(handles.GUI_B.h);

The problem with this code is that it does an infinite loop... I would like to know if there is a way to send an information from GUI_B to GUI_A. Like (Code in GUI_B) :

function PushButton_Callback (hObject,~)
  if get(hObject,'Value')
     %Do stuff
     send(hObject,'Value') to GUI_A
  end

Or even a way to unpause GUI_A from GUI_B.

Anyway, I'm open to all proposals !!

Thanks all, Clément.

Actually it works with waitfor(handles.GUI_B). ;)
