How should i realize that the string in the text uicontrol will automatically update when the checkbox is clicked.

function [] = gui_test()
% click a checkbox puts the string in a textbox.
S.fh = figure('units','pixels',...
    'position',[300 300 600 400],...
    'menubar','none',...
    'name','test',...
    'numbertitle','off',...
    'resize','off');
S.cb = uicontrol('style','checkbox','string', 'water',...
    'units','pix',...
    'position',[200 300 100 30],'Callback',{@cb_Callback});
S.tx = uicontrol('style','text',...
    'unit','pix',...
    'position',[200 100 180 30]);
   function cb_Callback
   set(S.tx,'String',get(S.cb,'String'));  
   end
end

Thank you for your help.

When you use ... as the continuation marker, the next line cannot be empty or consist of comments only. If that next line does not finish the previous then there must be at least a continuation marker.

I added the empty lines to show them as code on this web. The real code doesn't have this problem.

Add another 'end' statement at the end of what you have, so that there is an 'end' for cb_Callback and another end for gui_test() but which is after the 'end' for cb_Callback.
