MATLAB: Smooth transition (optical effect) between uitabpanels

functionguiMATLABuicontrol

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.

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.

MATLAB: How to set the SelectionChangedFcn for the tabs group I have created

By writting the code like this:

%Setting the uipanel1 height, width and position as figure1
handles.uipanel1.Position = [0 0 handles.figure1.Position(3) handles.figure1.Position(4)];
%This line of code has to come before creating the tab group, otherwise the
%tabs won't have the same width height and position as figure 1, only the
%first one will.
% Create tab group with SelectionChangedFcn
handles.tgroup = uitabgroup('Parent', handles.figure1,'TabLocation', 'top','SelectionChangedFcn',...
    @(hObject,eventdata)Frogsim('tgroup_SelectionChangedFcn',hObject,eventdata,guidata(hObject)));
    % This line tells the uitabgroup function that the name of the callback
    % function for the selection change is named tgroup_SelectionChangedFcn
    % , and also sends in the input argument guidata(hObject) which is the
    % updated structure of handles and data , the eventdata is sent
    % automatically.
handles.tab1 = uitab('Parent', handles.tgroup, 'Title', 'Materials and Optics selection');
handles.tab2 = uitab('Parent', handles.tgroup, 'Title', 'Dispersion graphs');
handles.tab3 = uitab('Parent', handles.tgroup, 'Title', 'My Tab Label 3');
% Place panels into each tab
set(handles.uipanel1,'Parent',handles.tab1)
set(handles.uipanel2,'Parent',handles.tab2)
set(handles.uipanel3,'Parent',handles.tab3)
% Reposition each panel to same location as panel 1
set(handles.uipanel2,'position',get(handles.uipanel1,'position'));
set(handles.uipanel3,'position',get(handles.uipanel1,'position'));

Then the SelectionChangedFcn callback for the tab group called tgroup is set correctly. In this case my gui is called Frogsim , if your gui is called mygui then the third line should look like this:

    @(hObject,eventdata)mygui('tgroup_SelectionChangedFcn',hObject,eventdata,guidata(hObject)));

Later in the code I wrote the SelectionChangedFcn for tgroup like this:

% --- Executes on selection change of tabs in tgroup tab group.
function tgroup_SelectionChangedFcn(hObject, eventdata, handles)
% hObject    handle to tgroup (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

And then you can add whatever code you want to the selection change function.

To explain better what the third line did, the line of code:

@(hObject,eventdata)Frogsim('tgroup_SelectionChangedFcn',hObject,eventdata,guidata(hObject)));

creates an anonymous function that accepts the arguments

hObject
eventdata

then the anonymous function calls the function:

Frogsim('tgroup_SelectionChangedFcn',hObject,eventdata,guidata(hObject)));

what that does is to call the tgroup_SelectionChangedFcn function within Frogsim with arguments hObject and eventdata (That were passed inside by the anonymous function) and then the 3rd input argument is guidata(hObject) which will give the updated structure of handles and user data in a guide built gui, and that corresponds to the 3rd arguments of SelectionChangedFcn which is

handles

MATLAB: WindowButtonDownFcn conflicting with ButtonDownFcn

You can insert an axes object spanning this whole figure as a background and use its ButtonDownFcn:

BGcolor = get(0, 'DefaultFigureColor');
BGaxes = axes('Units', 'normalized', 'Position', [0,0,1,1], ...
              'XTicks, [], 'YTicks', [], ...
              'Color', BGcolor, 'XColor', BGcolor, 'YColor', BGcolor, ...
              'ButtonDownFcn', 'disp(''Background'')');
DataAxes = axes('ButtonDownFcn', 'disp(''Data'')';
