So i have a variable totalMax that updates every time a check box is checked. There are 9 check boxes, and each update the table in certain ways, which then updates totalMax. (this happens in a seperate function I wrote, and each checkbox call back function executes it).

Currently I print totalMax into a string using sprintf and then save it into an GUI object = using this function:

function handleNewMax(handles, new_max)
      handles.maxCap = new_max;
      guidata(handles.output, handles);

And in the edit box call back function i do this:

   handles = guidata(handles.output);
  set (hObject, 'String', handles.maxCap);

It works out fine and everything. BUT it only will update if i press enter in the box. Is there a way to have the text box automatically update, specifically if I update totalMax? (or teh string i put it in)?

Thanks

OH i just realized, it is simpler that i thought it was. So i have been looking for solutions to this problem and it seemed so simple just put 'set(handles.edit3, 'String', Maxcfs_str)' but there were issues. But I put this in a function I wrote,and there were issues accessing handles.edit3. BUT if I pass in hObject, eventdata, and handles, into the custom functio i wrote, the set function works fine.
