Hi everyone,

I have a figure opened with two push buttons. While clicking each of the buttons, the value of a certain variable changes.

I would like to make it so the figure also closes once one of the buttons is pressed.

I have tried many variations in order to do this but none work, since I am trying to add 2 functions to the same call back. I know I can create an external function to do this, but it seems redundant.

Is there a simple way to apply this?

Thank you so much!

Hello Walter, Thanks for the reply!

Actually I'm not using GUIDE. Here is an example for the part I'm working on:

lang_eng = uicontrol('style', 'pushbutton',...
                     'fontsize', 12,...
                     'string', 'English',...
                     'units','normalized',...
                     'position', [0.55 0.5 0.2 0.1],...
                     'callback', 'lang = eng', 'callback', 'close all');

Obviously it doesn't work that way :)

Thank you!

Is there any way to have two callbacks in the form

uicontrol('Callback',@myfunction);
uicontrol('Callback','uiresume(gcbf)');

included in the same "uicontrol"?

Many thanks!

It sounds as if you might be using GUIDE. If so use the Property Inspector to edit the Callback property, which will be a string. You can edit the string to close() the figure handle.

Caution: there is a possibility that the Callback might get changed back by GUIDE.
