toggle button callback did not function
显示 更早的评论
function closepump_Callback(hObject)
%CLOSEPUMP Summary of this function goes here
% Detailed explanation goes here
global GUI
if get(hObject,'value')==1 % button down
set(hObject,'BackgroundColor',GUI.offcolor,... %yellow = pump running
'string',[valves open]);
elseif get(hObject,'value')==0 %button up
set(hObject,'BackgroundColor',GUI.menucolor,...
'string',[valves close]);
else
fprintf(2, 'callback object value was not 1 or 0, was %g\n', get(hObject,'Value'));
end
this is my callback of a togglebutton. However it said there are too many input arguments. How can I fix it?

Try this:
function closepump_Callback(hObject, eventdata, handles)
I suspect the last two inputs somehow got deleted by accident.

No, that would not have made the difference for that error message. However, the missing input arguement locations would make a difference. See for example your July posting about this same software, in which you had coded
function checkpump(hObject, ~, ~)
Notice three input arguement slots.
