GUI Slider value doesnt change
이전 댓글 표시
Hi, I created a slider in my GUI. the problen - moving the slider doesnt chage the value (when i am debuging and loocking at handles.slider.value or hObject). when seting the value it does move the slider, but bot the other way around. Please help!
more info:
initialy i set the slider as 'off'. when another buttton activates it. the SliderStep is determened by another parameter in the gui, and is changed all the time.
the min is 0, max is 1.
my code:
function slider_time_Callback(hObject, eventdata, handles)
g = get(hObject, 'Value')
h = get(handles.slider_time, 'Value')
function slider_time_CreateFcn(hObject, eventdata, handles)
if isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
set(hObject,'BackgroundColor',[.9 .9 .9]);
when g and h are 0 after moving the slider.
THANKS!

Taly - please clarify what you mean by _i set the slider as 'off'_. And are you sure that the callback is being called when you move the slider? You may need to attach an example GUI that exhibits this behaviour.

Also, your callback doesn't actually do something. It creates two variables that are wiped after this function quits.
