Hi, Rahma

I have seen your picture.

I think I cannot do it with your way.

Imagine if we have A-m-5 in 1st component and we also have c in 2nd component.

The pushbutton cannot decide which one must be stored in history, right?

So, I think we need 2 pushbutton to perform this. One in 1st component and another one in 2nd component.

The figure is shown below :

And the code :

In openingfcn

function untitled_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
handles.cnt = 0;
handles.history = {};
handles.p1str = {'Process1','A','B','C','D','E'};
handles.p2str = {'Process2','m','n'};
handles.p4str = {'Process4','a','b','c'};
set(handles.popupmenu1,'string',handles.p1str);
set(handles.popupmenu2,'string',handles.p2str);
set(handles.popupmenu3,'string',handles.p4str);
set(handles.slider1,'value',0,'sliderstep',[.05 .05]);
guidata(hObject, handles);

In slider1 callback

function slider1_Callback(hObject, eventdata, handles)
val = get(handles.slider1,'value');
val = round(val*20);
set(handles.text5,'string',num2str(val));

In pushbutton1 callback

function pushbutton1_Callback(hObject, eventdata, handles)
p1val = get(handles.popupmenu1,'value');
p2val = get(handles.popupmenu2,'value');
p3val = get(handles.slider1,'value');
p3val = round(20*p3val);
if (p1val > 1) & (p2val > 1)
    handles.cnt = handles.cnt + 1;
    histstr = horzcat(handles.p1str{p1val},', ',...
                                handles.p2str{p2val},', ',...
                                num2str(p3val));
    handles.history{handles.cnt} = histstr;
    set(handles.listbox1,'string',handles.history);
end
guidata(hObject,handles

In pushbutton2 callback

function pushbutton2_Callback(hObject, eventdata, handles)
p4val = get(handles.popupmenu3,'value');
if p4val > 1
    handles.cnt = handles.cnt + 1;
    histstr = handles.p4str{p4val};
    handles.history{handles.cnt} = histstr;
    set(handles.listbox1,'string',handles.history);
end
guidata(hObject,handles);

You can also download the file and do modification on it for your purpose.

I hope this works!

but, the string of PopupMenu has been included by GUI. when i try the code, the string of PopupMenu be empty .. it became ' , , 2'.. how can I get the string of PopupMenu that I have made ..?

[Chandra Kurniawan]

popstr = get(handles.popupmenu1,'string')

But this command returns all strings included in the popupmenu1.

You cannot directly get the choosen string from the popupmenu1, you should get the index first by :

popval = get(handles.popupmenu1,'value')

then followed by :

popslc = popstr{popval}

[Rahma Yeni]

so far, the code that you give running well ..

but there is one more problem ..

I use two figures on this project ..

all previous code in figure 2 .. I used to like this http://www.mathworks.com/matlabcentral/answers/29639-linking-guis-in-matlab ..

why the code to display history, always error on the first time running ..?? but when i minimize the figure, then I run again using F5, the history can be appear ...

[Chandra Kurniawan]

please describe it clearly.

so, in the first GUI you have a pushbutton to link the second GUI?

[Rahma Yeni]

sorry... :)

yes,, in the first GUI i have a pushbutton to link the second GUI..

image in first GUI move to second GUI..

but, when i do 'make history', the choices are not appear in history list ..

it is the message:

??? Reference to non-existent field 'cnt'.

But, when i minimize the figure, then i run it again, the choices appear to history list..

[Rahma Yeni]

like make history before, but i have the other example..

http://www.flickr.com/photos/rye_ni/6969686871/

where, string of 'b' and 'c' take the value from their text field. how i can make history like before..?? cause, one of the process have different text field..

thanks before Mr. Chandra.. :)

nice for your answer..
