I have been trying to create a multi window app just like the example in the documentation but its not working.
I think the problem is that i am not able to get my secondary app start function to be startFnc(app, mainapp, x, y) like the example. what I keep getting is startFnc(app, event)
and the error is too many parameters when I click th button to open secondary window
the code line at the error is app.dialogApp=newwindowname(app,x,y)
any advice?

ok so the code follows exactly the help on multiwindows in the link below
the error shows at option button callback at the second line (btw app.x and app.y are defined under private properties just like the example above thats why im suspecting the start function of the new window since i cant get it to match the one in the example (i.e startFnc(app, mainapp, x, y) ) )
%disable plot options button while dialog is open
app.OptionsButton.Enable = 'off';
%open the options dialog and pass input
app.DialogApp = New_window_name(app, app.x, app.y);
the error inside app desinger is "Error using new_window_name Too many input arguments"
in the command window the error is
" Eror using new window name Too many input arguments
Error in Main_window/OptionsButtonPushed
app.dialogApp = new_window_name(app, x, y);
Error using matlab.ui.control.internal.controller.componentController/executeUserCallback
Error while evaluating Button PrivateButtonPushedFcn"

The starup function in app 2 will have its own 1st input "app". You shouldn't pass that into the app.
Try this.
app.DialogApp = New_window_name(app.x, app.y);
If that doesn't solve the prblem, please provide,
  1. The new full error message if one exists (copy-pasted or screen shot)
  2. The Startup function in app 2.
