Protecting the GUI with a Close Request Function

Whenever a user closes a figure, MATLAB first executes the figure’s close

request function, as defined by the

CloseRequestFcn figure property. The

default close request function simply deletes the figure. However, a GUI may

want to protect the user from unintentionally deleting a figure if they click on

the

X in the close box of the window border.You can change the default close

request function by redefining the figure’s

CloseRequesFcn.

The “The Close Button Callback” section shows a callback for the GUI’s

button that you could also use as a close request function. To add the new close

request function to your application M-file, select the figure in the Layout

Editor and right click to display the context menu.
