Calling Matlab GUI popupmenu callback on click

Hi,

I would like to update the options that should be shown in a popupmenu of a Matab GUI each time it is clicked on it. When I implement this functionality in the callback function, it only works when one of the choices is selected, not when the down arrow is clicked.

Is there any way to create a callback function that works when the down arrow is clicked, before selecting any of the options of the menu?

Thanks!!

This question has already been asked before and there's a rather detailed explanation.

Please see the link : How to pass data from one GUI to another?

No, there is no callback in the Matlab level.

You can use the Java callbacks, if your "Matlab GUI" is a figure, see https://undocumentedmatlab.com/blog/uicontrol-callbacks , but I do not know a method for uifigure windows.

I have simulated a popup menu in a similar case by a uicontextmenu and some graphical elements, which look like a popup. It works, but actually it is the porgrammers hell to emulate standard GUI elements.
