how to keep waitbar on the application

i tried to use waitbar in an apllication and want it to be built up in the application not seperate. Thank you

f = waitbar(0,'1','Name','Optmization Process...',...
    'CreateCancelBtn','setappdata(gcbf,''canceling'',1)');
setappdata(f,'canceling',0);
 
steps = gen;
 
for step = 1:0.01:steps
    % Check for clicked Cancel button
    if getappdata(f,'canceling')
        break
    end 
    
    % Update waitbar and message
    waitbar(step/steps,f,sprintf('%12.1f',step))
    
end
 
 
delete(f)

Gali - are you using App Designer to integrate the waitbar? It is difficult to read the code that you have posted above so it would be preferrable if you could copy and paste the code to this question.
