How to automatically fill a listbox with for loop ?

3 views (last 30 days)
%% I have this example of code
for i = 1:1:10
T = randi([0 10],1,1); % random number between 0 and 10
R = num2str(T);
listbox1.add(i,R); %%this line is adding only one number to the list
%%I want to add all these numbers in the JList

The first step is working now. I have a textfield in the Figure. I want to write the selected number in that textfield.
See attached File to understand.

In this last version, the selected item index is reported on the textfield. I want the item string, not its index.

Try this:
numItems = 10;
for k = 1 : numItems
T = randi([0 10],1,1); % random number between 0 and 10
oneCell = {sprintf('%d', T)};
listboxItems(k) = oneCell;
% Optionally, print cell array to command window so we can see it.
% Send this cell array to the listbox
set(handles.listbox1, 'String', listboxItems);

Thanks Image Analyst, It is working very well now.
When I select it and press a button, the selected number is sent to the textfield.
Thank a lot.
Now I can complete the code with real data.
