MATLAB: PushButton HitCounter / simple question

buttondefine variable

hey Guys,
I want to create a program, which includes a Code, that counts how many times u clicked on a button. My Thought was….use x = x +1 but where do I define x as 0 ?
here, it wont work
x = 0 
function pushbutton8_Callback(hObject, eventdata, handles)
x = x +1
.......
here, it will always set x back to 0
function pushbutton8_Callback(hObject, eventdata, handles)
x = 0 
x = x +1
PS: Sorry for that stupied Question

Best Answer

Add
handles.counter = 0;
in the GUI opening function. Then in the pushbutton, increment the counter
handles.counter = handles.counter + 1;
Remember to add
guidata(hObject, handles);
at the end of the opening function and of the pushbutton callback.
