How do I update my slider using an edit text?

So my edit text is able to change the value of my slider, but only after the slider is clicked on, is there any way that the slider could be updated continuously or after I hit enter? Here is my code in the slider callback:

val=str2num (get (handles.edit1, 'String'));
set(handles.slider1, 'Value', val);

I would suggest that you create a generic callback function, and give each of your objects a Tag with an appropriate name.

In this case, the edit box would have

set(handles.edit1,'Tag','handles.edit')

and slider would be

set(handles.slider1,'Tag','handles.slider1')

Assign a generic callback to each

set(handles.edit1,'Callback',@genericCB)
set(handles.slider1,'Callback',@genericCB)

Now you create the generic callback that reads the Tag

function genericCB(src,eventdata)

handleLink = get(src,'Tag')

if any(regexp(handleLink,'edit1'))

% The edit1 object was called, update slider1

elseif any(regexp(handleLink,'slider1'))

% The slider1 object was called, update edit1

end

Edit: When you enter a value into the edit box, the callback will not be called until you click outside of the edit box or press on the keyboard. If you want the slider to update as you are typing, I believe you'll need to create a java object instead of a uicontrol object

To make the slider update when the editbox is updated, put the update code in the editbox callback

function myEditBox_Callback(hObject,eventdata,handles)

val = str2double(get(hObject,'String'));
set(handles.slider1,'Value',val);

guidata(hObject,handles)

And then, in the slider's callback:

function slider1_Callback(hObject,eventdata,handles)

val = get(hObject,'Value');
set(handles.myEditBox,'String',num2str(val));

guidata(hObject,handles)
