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 :
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/169404/image.jpeg)
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!
