Problem with multi-line in TextEdit box

Hi, I cannot find a way to display the text in multiple lines in text edit box. I read that I all I need is to set property Max to be larger than Min (e.g. Max = 2), but this does not do the trick. For test purpose I have simple GUI, with only one text edit box and one button. "Pushbutton1_Callback" function executes the following code:

   for i =1 :100
   set(handles.edit1,'String', [num2str(i), '  test'] ); 
   pause(0.1);
   end

However, all i get on the box is single line. How can I fix this to obtain multiple lines like this:

1 test

2 test

3 test ....

Thank you!

stani7062 - in your above for loop, you are replacing the String property for the text box on each iteration of the loop. Rather than replacing, you should be appending. Try the following instead

 for i =1 :100
      strData = get(handles.edit1,'String');
      if isempty(strData)
          strData = {};
      end
      strData = [strData; [num2str(i), '  test']];
      set(handles.edit1,'String',strData);
 end

In the above, we check to see if the current data, stdData, is empty or not. If so, then we set it to an empty cell array so that we can append the new strings to it (with the semi-colon, we ensure that each new string is appended as a new line or row).

Thank you Geoff, this works great!
