MATLAB: Changing color of Button

Question

With some help i've created a variable amount of buttons in my gui:

for n=1:s
handles.b{n}=uicontrol('Style','PushButton','Units','pixels', 'Position',[125-breiteQuadrat/2-5+breiteQuadrat*n 45 10 10],'Visible','on');    
end

Now i want to colour the button when it is selected and when you click twice it has the start-colour. here i call the callback function:

for n=1:s
set(handles.b{n},'Callback',@(obj,event)varBButton_Callback(n,hObject,eventdata,handles));    
end

for the callback i implemented a new function:

function varBButton_Callback(n,hObject, eventdata, handles)
if get(handles.b{n},'Value')==get(handles.b{n},'Max')
set(handles.b{n},'BackgroundColor',[1 0 0],'Value','Min');
set(handles.tauschButton,'enable','on');
set(handles.deaktivierenButton,'enable','on');
else
set(handles.b{n},'BackgroundColor',[1 1 1],'Value','Max');
end
guidata(hObject, handles);

the change of the value doesn't work but i can't find my mistake.

and after that i want that it is possible to remove or change the position of the selected button. maybe someone has an idea how to realize that problem Thank you

Answer 1

Probably this line is the problem:

set(handles.b{n},'BackgroundColor',[1 0 0],'Value','Min');

The 'Value' property can't be a string 'Min'. You probably mean to be:

set(handles.b{n},'BackgroundColor',[1 0 0],'Value',get(handles.b{n},'Min'))

Same problem for the other line.
