Assign same panel to different tabs UITAB

I am currently trying to create a gui in GUIDE. I have created 2 tabs using uitab in a uitabgroup. I have 2 panels, of which 1 is changing when you switch between tabs (panel P1a and P1b). The other should remain the same (P2). My question is, how can I see panel P2 in both tabs? Code is as follows:

handles.tgroup = uitabgroup('Parent', handles.figure1)

handles.tab1 = uitab('Parent', handles.tgroup, 'Title', 'Import Text')

handles.tab2 = uitab('Parent', handles.tgroup, 'Title', 'Import Excel')

set(handles.P1a,'Parent',handles.tab1)

set(handles.P2,'Parent',handles.tab1)

set(handles.P1b,'Parent',handles.tab2)

set(handles.P2,'Parent',handles.tab2)

Currently, this code does not work, since I only connect P2 to tab2 because of the last line.

Thanks, Reinier

Just reparent it in the 'SelectionChangedFcn' callback of the uitabgroup. It only needs to be parented by a tab if that tab is the currently selected one since you can never view 2 tabs at the same time.

Thanks, that sounds like it should work. Is there a way to specify in GUIDE the SelectionChangedFcn callback of the uitabgroup? I am unsure how to code it in the current structure (usually callbacks are created automatically when I create the lay-out in GUIDE). Currently I have tried this (based on my previous code):

 function tgroup_SelectionChangedFcn(hObject,eventdata,handles)

    selectedTab = get(hObject,'SelectedTab'); 
    if strcmp(selectedTab,'Import Text')==1
      set(handles.P2,'Parent',handles.tab1)
    elseif strcmp(selectedTab,'Import Excel')==1
      set(handles.P2,'Parent',handles.tab2)
    end

 guidata(hObject,handles);

Tabs are not supported in GUIDE so you have to do them programmatically, but I assume you have already created your uitabgroup programmatically anyway?

Something similar to this should work

hPanel = uipanel( ... )
hMainTabGroup = uitabgroup( ...
   'Parent', hFig,...
   'SelectionChangedFcn', @(src,evt) tabChangedCallback( evt, hPanel ) );

function tabChangedCallback( evtData, hPanel )
    hPanel.Parent = evtData.NewValue;
end

Thank you so much, I managed to get it to work.

In GUIDE the last 'end' is not allowed though, fyi
