MATLAB: Get the selected value in a popup menu with a set

listmenupopupselectedvalue

Hello,

Is is possible to set the list of the popup menu (with set(handles…..)) and still get which one is selected? I did use set to have my different choices in the popup menu. But when i want to know which one is selected, it gives me the list that i had set… How can i get the selected value only?

if true
te = T(:,3); %one column of an excel file with number (101-109, 201-209,...409)
set(handles.popupname, 'String', table2array(te));
end

Thank you

jacques - if you want to get the selected item you would first get the index of the selected value

 idx = get(handles.popupname,'Value');

Once you have the index, you can then determine which is the selected item from your list

 items = get(handles.popupmenu1,'String')
 selectedItem = items{idx};

vedesh - in the pushbutton callback, you would use the handles structure to get the selections from the two dropdown menus. Your code could look something like the following

function pushbutton1_Callback(hObject, eventdata, handles) 
% get the selection from the first drop down menu
popup1List = get(handles.popup1,'String'); % get the list of items of popup1
popup1Index = get(handles.popup1,'Value'); % get the index of the selected item of popup1
popup1Value = popup1List{idx};             % get the value of the selected item of popup1
% get the selection from the second drop down menu
popup2List = get(handles.popup2,'String'); % get the list of items of popup2
popup2Index = get(handles.popup2,'Value'); % get the index of the selected item of popup2
popup2Value = popup2List{idx};             % get the value of the selected item of popup2
% note that popup1Value and popup2Value are strings so you may need to convert to numbers is
% applicable
% do whatever work you need to and draw line on axes

Try this:

allItems = handles.popupname.String;     % A cell array of all strings in the popup.
selectedIndex = handles.popupname.Value; % An integer saying which item has been selected.
selectedItem = allItems{selectedIndex};  % The one, single string which was selected.
YourOtherFunction(selectedItem);  % Pass the string to some other function of yours.
