The first parameter passed to a UI Figure Close Request Fcn callback is not the app: it is the handle of the component that requested the callback (so, typically the handle of the uifigure)

Unless, that is, you configured the callback as an anonymous function that substitutes app for the normal first parameter.

i click with taste dx on tab..but i dont see it

i want to save data whn i close tab

[Walter Roberson]

CellSelection callbacks are for uitable(), so you are not clicking on a uifigure, you are clicking on a uitable. There is no close request callbacks for uitable . You need to click somewhere in the uifigure that is outside of the uitable in order to be able to set the callback.

i find it:

but it link my precedence code

the app is correct...it's information about my tab (34*19 it's my tab)

(i tried to change below something in the code but result doesn't change)

Notice that app.Setting is [] but you are trying to access app.Setting.Instrument
