Can't see the fields of my GUI variables in workspce

I am writing a GUI program with matlab. The program is working fine, but when i run it in debugging mode to follow the changes of my variables through the workspace, handles structure is represent as 1X1 struct whitin each variable has value from double type. i Update handles structure every time i make a change of variable. so why i can't see the fields of every variable when i go to check it in the workspace?

I predict that you are using R2014a or earlier, and that the values you are storing in the handles structure are handles of graphics objects.

In R2014a and earlier, the handles of graphics objects are represented as double precision numbers. Therefore in those versions, if you did something like

handles.editbox = uicontrol('style', 'edit', 'String', 'cricket');

then what would get stored at handles.editbox would be the double precision value that the graphics subsystem would know referred to the graphics object. In order to see the properties of the object you would need to get() on the object, like

get(handles.editbox)

In versions from R2014b onwards, graphics objects are represented by Objects in the Object Oriented Programming sense, and so display differently.
