MATLAB: Callback Function of uimenu

callback functionsguiuicontroluimenu

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?

Best Answer

  • 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
