function listbox1_Callback(hObject, eventdata, handles)
contents= cellstr(get(hObject,'String'));
listchoice=contents(get(hObject,'Value'));
if(strcmp(listchoice,'a'))
    lis1=10;
elseif(strcmp(listchoice,'b'))
    lis1=20;
elseif(strcmp(listchoice,'c'))
    lis1=30;
elseif(strcmp(listchoice,'d'))

I have a listbox in which a user can select multiple choices and a popupmenu with their corresponding choices. In the edit text box i want the multiplied result of selected values(which is to added as the user can select more than one items) of listbox and poupmenu.

function listbox1_Callback(hObject, eventdata, handles)
contents= cellstr(get(hObject,'String'));
lischoice=contents(get(hObject,'Value'));
if(strcmp(lischoice,'a'))
    l_value=0.10;
elseif(strcmp(lischoice,'b'))
    l_value=0.20;
elseif(strcmp(lischoice,'c'))
    l_value=0.30;
end
set(handles.listbox1,'Userdata',l_value);
assignin('base','l_value',l_value);
function popupmenu1_Callback(hObject, eventdata, handles)
contents=cellstr(get(hObject,'String'));
popchoice1=contents(get(hObject,'Value'));
if(strcmp(popchoice1,'x'))
    pop1val=10;
elseif(strcmp(popchoice1,'y'))
    pop1val=20;
elseif(strcmp(popchoice1,'z'))
    pop1val=30;
end
set(handles.popupmenu1,'UserData',pop1val);
assignin('base','pop1val',pop1val);
function pushbutton1_Callback(hObject, eventdata, handles)
pop1val=evalin('base','pop1val');
l_value=evalin('base','l_value');
c=pop1val*l_value;
set(handles.edit1,'String',c);

How can I select multiple items from a GUI listbox?

ANURAG DEEPAK 2019-9-19

function listbox1_Callback(hObject, eventdata, handles)
contents=cellstr(get(hObject,'String'));
lischoice=contents(get(hObject,'Value'));
set(handles.listbox1,'Value');
assignin('base','lischoice',lischoice);

With this above code i am able to select multiple items in listbox, but this is giving only cell array (String). So how can i provide values to choices made in listbox and add them up?? (With reference to above codes).

This is not the best way but a working solution!

function listbox1_Callback(hObject, eventdata, handles)
contents= cellstr(get(hObject,'String'));
lischoice=contents(get(hObject,'Value'));
if numel(lischoice)>=2
choice1 = lischoice(1);
choice2 = lischoice(2);
    if (strcmp(choice1,'a'))
        l1=0.10;
    elseif (strcmp(choice1,'b'))
        l1=0.20;
    elseif (strcmp(choice1,'c'))
        l1=0.30;
    end
    if (strcmp(choice2,'a'))
        l2=0.10;
    elseif (strcmp(choice2,'b'))
        l2=0.20;
    elseif (strcmp(choice2,'c'))
        l2=0.30;
    end
l_value = l1 + l2;
else
    if (strcmp(lischoice,'a'))
        l_value = 0.10;
    elseif (strcmp(lischoice,'b'))
        l_value = 0.20;
    elseif (strcmp(lischoice,'c'))
        l_value = 0.30;
    end
end
assignin('base','l_value',l_value);
