Callback Function of uimenu

I wrote the callback functions to undo and redo to activities, and I can use these functions for pushbuttons(undo and redo buttons). But when I use the same callback functions for menu items, I get an error:

How can I fix this?

[Mehmed Saad]

when uimenu (undo redo) callback goes to undo or redo functions, the parent of the hObject is uimenu and not the figure itself. The parent of uimenu is figure. which means if you want to call figure, you have to write

hObject.Parent.Parent

so when you call

entries=hObject.Parent.UserData;

for uimenu, the parent is uimenu and not the figure while for buttons of redo and undo the parent is figure itself

the best option is change

hObject.Parent

with

handle

in your code
