MATLAB: Saving strings in to GUI dynamic Listbox in a loop

for loopguilistboxset

Hi, I am trying to save a list of words and set them in a GUI listbox dynamically. This is my loop:
   L = length(scchildren1)
   c= 1;
     for z=1:L
      A= A+1;
      B= A;
      B =int2str(B);
      B= scchildren1{z}
      set(handles.listbox2,'String',B, 'Value', c);
      B= str2num('B');
      B= B+1;
      c= c+1;
end
I don’t know which property of listbox I can access to change line for each save operation. I thought maybe ‘Value’, but false. Now the problem is I am saving all words in one place in each iteration and at the end remains only one. Any idea would be helpful. Thanks

You can't insert just one item into a listbox. You have to send in the whole string. So you need to make up a cell array of strings and then send that in. for what you did, no for loop is needed:
listboxItems = scchildren1(1:z);
set(handles.listbox2,'String', listboxItems );
If you then want to highlight/select a particular item in the listbox, then is when you set the value property:
set(handles.listbox2, 'Value', someIndexYouWant);
Note that if you have multiselect on then someIndexYouWant can be a vector. if it's a single selection listbox, someIndexYouWant must be a single number.
