MATLAB: Call a gui callback without handles

MATLABmatlab gui

Hello all, I'm using Tab Manager for my uipanel management. The problem here is when i change my tabs the callback doesn't have handles in its function–> tabChangedCB(src, eventdata), So here i can't call a gui callback without a handles from within this function. I want to do some calculation when this tab is changed.
Is there any possibility to simulate a button press in the gui, such that it will be called from gui not as a function?
ThankYou.

You can still use guidata normally. The source (to which a handle is saved in scr) can still be used to follow the chain of parents up to the figure.
handles=guidata(src);%this should get the handles for you
