How to send a result value from one gui to another gui?

I have 2 gui (say A.fig is main gui and B.fig is the other one). In A.fig i have a button 'Detect' to detect an object in picture (the result is string, like rectangle/square/triangle/circle). And there's a button 'Change' that call and show B.fig.

In B.fig i have a popupmenu, but i want the string in popupmenu was depend on the result from button 'Detect' in A.fig.

For example, if the result from 'detect' button is rectangle, when i click 'change' button and show B.fig, the list of popupmenu is cube and pyramid. If the result is triangle, the list is prism and pyramid; if circle, the list is ball and tube.

And my problem is, how to send the result value from 'detect' button in A.fig to B.fig that i use to determine the list of popupmenu in B.fig??

%use mat file

%for example x y z your data

 save file x y z

%to get your data

 data=load('file')
 x=data.x
 y=data.y
 z=data.z

And how would GUI B know when it's time to load this (i.e. a few seconds after A saved it)? Would you have GUI B running a timer and checking the file date.

[Azzi Abdelmalek]

I don't know exactly how are his gui programs, but when his B gui is launched the opening function will load mat file then set popupmenu parameters

[Image Analyst]

I could be wrong, but I think he wants B to update every time he presses the button in A, not just when B is launched for the first time.

[Azzi Abdelmalek]

then he can add an update button in his second gui. it's not the better way, but it can help

to Azzi Abdelmalek : so i must save the result in mat file everytime i press the button in A? but how if i don't want to add an update button in my second gui? Can i update automatically when i press the button in A?

to Image Analyst : yes, you right. I want B is update every time i press the button in A. Is it possible?

which part is related with my problem?

[Walter Roberson]

B_handles = guidata(B_figure_handle);
set(B_handles.detect_popup, 'String', {'triangle', 'square'});
guidata(B_figure_handle, B_handles)
