matlab - Passing arguments to UIcontrol callback function -

i making app track finances , confused how pass string callback function in uicontrol pushbutton object.

for instance:

classdef moneyapp < handle methods (access = public)         function app = moneyapp             % uicontrol object example             app.newsymbolglmc = uicontrol(app.figureglmc,...                    'style','pushbutton','position',[300 60 200 20],...                 'string','new stock',...                 'callback', {@app.newstock,'account name'});         end         function newstock(src,eventdata,account)             % string, 'account name'         end     end end  

end

i confused how string, 'account name', newstock function. essential part code , think syntax not correct; more examples of code can provided if needed. appreciated!

since newstock method of class, first input must object itself. because of need 4 input arguments in function definition: instance, source , event data (the default inputs), , account name.

function newstock(obj, src, eventdata, account) 

as side note, capitalization of constructor (moneyapp) must match capitalization of class (moneyapp) treated constructor.
