Change message in static text in a gui -loop

Question

Hi guys,

I am having some trouble changing a static text in a gui. I have a loop and a message that changes along that loop.

I want the message in the static text to change with it.

I have tried using set() but it isn't working...

For example:

 If x=2
   d='True';
 else 
   d='False';
 end
 set(handles.statictext,'String',d);

Can anyone help?

Thanks in advance!

Inês

Use double equals and not equals. Also use if not If, and use drawnow. Try it like this:

if x==2  % Use == not =
   d='True';
else 
   d='False';
end
set(handles.statictext,'String',d);
drawnow; % Force immediate update.

You probably did not give the "tag" property of your static text label. Put

handles

right before the set() call, and see what values it lists for handles. Your static text label should be one of the names listed.
