In conclusion, the ButtonDownFcn and SelectionChangeFcn functions of an UITAB are already active when you click in the tab´s label. So it is not possible to achieve the desired target (smooth optical transition) because the obtained result (modifying the mentioned functions) is the same that doing nothing.
Smooth transition (optical effect) between uitabpanels

Hi. I have designed a group of three uitabpanels objects.
htab = uitabgroup('v0');
th1 = uitab('v0',htab,'title','Panel 1','ButtonDownFcn',...
@th1_ButtonDownFcn);
th2 = uitab('v0',htab,'title','Panel 2','ButtonDownFcn',...
@th2_ButtonDownFcn);
th3 = uitab('v0',htab,'title','Panel 3','ButtonDownFcn',...
@th3_ButtonDownFcn);
My intention is having a smooth optical transition between them when I change the selected uipanel through the mouse click. I pretend to achieve it changing the 'Visible' property of the elements contained inside them using the ButtonDownFcn function ( I got this idea based on the description section of http://www.mathworks.com/matlabcentral/fileexchange/4780-tab-panel-yet-another-one).
set(handles.th2,'Visible','off');
set(handles.th3,'Visible','off');
...
function th1_ButtonDownFcn(hObject, eventdata)
handles = guidata(fh);
set(handles.th1,'Visible','on');
set(handles.th2,'Visible','off');
set(handles.th3,'Visible','off');
guidata(fh,handles);
end
function th2_ButtonDownFcn(hObject, eventdata)
handles = guidata(fh);
set(handles.th1,'Visible','off');
set(handles.th2,'Visible','on');
set(handles.th3,'Visible','off');
guidata(fh,handles);
end
function th3_ButtonDownFcn(hObject, eventdata)
handles = guidata(fh);
set(handles.th1,'Visible','off');
set(handles.th2,'Visible','off');
set(handles.th3,'Visible','on');
guidata(fh,handles);
end
where
fh: handle of the figure where they are contained the uitabpanels.
handles.th1, handles.th2, handles.th3: handles of the elements contained into each uitabpanel respectively.
However, it has not worked (I click on each one of uitabpanel's tabs and the visibility of them do not change) and I do not understand why.

The ButtonDownFcn of a UITAB is triggered, if you click in the tab's contents area. I assume you want to use the SelectionChangeFcn function of the UITABGROUP to detected a changed active tab.

@Julian: I admit, I do not get the point of "smooth transition". Do you mean an optical effect?
