MATLAB: Use a function inside button function inside the GUI

function in functiongui button colourgui function

if I have x buttons that have to change their background colour, and some text boxes colour once clicked;

inside button_1 function, I can write:

if get(handles.button_1,'BackgroundColor') == handles.off_colour

set(handles.button_1,'Backgroundcolor',handles.on_colour); set(handles.Rtext1,'Backgroundcolor',handles.on_colour) ;

elseif get(handles.button_1,'BackgroundColor') == handles.on_colour

set(handles.button_1,'Backgroundcolor',handles.off_colour); set(handles.Rtext1,'Backgroundcolor',handles.off_colour) ;

end

how can I use a function like function react(nr) inside: function button_1_Callback(hObject, eventdata, handles)

where nr=hObject.Tag(8:end) this will be the number of the button(1 2 3 … x) that is able to use utilise handles.(['button',nr']) handles.(['Rtext',nr'])

oh, I just need to send the handle also like react(nr, handle)

set( handles.textA, 'BackgroundColor', get( hObject, 'BackgroundColor' ) )

in your pushbutton callback, where handles.textA should be replaced by whatever your tag is for the static text.

MATLAB: How to create a function to change the color of a pushbutton

You can simply use cell11_Callback as callback function for all buttons, but use hObject instead of the hardcoded "handles.cell11". Or if you have any reason not to do this, you can call the function from other callbacks also:

% As you have posted already, but with hObject instead of the hard-coded
function cell11_Callback(hObject, eventdata, handles)
color=get(hObject,'BackgroundColor');
if(color==[0.94,0.94,0.94])
  set(hObject,'BackgroundColor',[0,0,0]);
elseif(color==[0,0,0])
  set(hObject,'BackgroundColor',[0.94,0.94,0.94]);
end
% And for the next button
function cell12_Callback(hObject, eventdata, handles)
% Call the other callback, but use the current hObject:
cell11_Callback(hObject, eventdata, handles)

By the way: This is shorter:

color = get(hObject, 'BackgroundColor');
set(hObject, 'BackgroundColor', abs(color - 0.94));
