Hello,

in guide I have few pushbuttons, uitables, radiobuttons.....few are enabled and few of them are disabled...

If I press button Calculate, than calculation is executed. During calculation I need disable all items. If calculation is finished, than enabled items before calculation have to be again enabled and disabled items before calculation have to be again disabled.

Haw can I do it?

msgbox? Or is there anything better?

Thank you

Each object in a GUI has a unique name which you can use to set parameters for. As an example, for a pushbutton you would use:

 set(handles.pushbutton,'Enable','on') 
 set(handles.pushbutton,'Enable','off')

to enable/disable the button with name pushbutton.

You can load all your handle IDs into an array and then just call that instead of doing them all individually:

handlesIDs = [handles.pushbutton1, handles.pushbutton2];
set(handlesIDs, 'Enable', 'off');

You just need to assign handlesIDs once at the beginning of your program and then just use it over and over. You can make it global, use setappdata(), or attach the array to handles.
