SliderSIX.m

Hi,

I have the issue in the slider with edit_text in GUI

When I fix the value in edit text, the slider moves but it doesnot update the slider variable until I touch the slider cursor. I nedd to use only one variable at fixing the value in edit_text as well as moving cursor automatically

Can you help in the below code

Best regards,

Venkat

Hi,
Thanks for the code but I have error below in the code
Error: File: SliderSIX.m Line: 175 Column: 1
The function "slider1_Callback" was closed with an 'end', but at least one other function definition was not. To avoid confusion when using nested functions, it is illegal to use both conventions in the same file.

I Don't Understand What You Are Trying To Achieve And What Isn't Working Well.

you can add a utility function that takes in the new value and sets it in the appropriate variable, and gets a list of controls to update...

something like that:

function onValueChanged(value, varName, updateGuiHandles)
    assignin('base', varName ,value);
    % lets assume updateGuiHandles is a cell array here
    for i = 1:length(updateGuiHandles)
        uih = updateGuiHandles{i};
        switch get(uih, 'Style')
            case {'edit'} % maybe others too
                if ~ischar(value)
                    v = num2str(value);
                else
                    v = value;
                end
                set(uih, 'String', v);
            case {'slider'} % maybe others too
                if ischar(value)
                    v = str2double(value);
                else
                    v = value;
                end
                set(uih, 'Value', v);
        end
    end
end
function onSliderValueUpdated(value, updateGuiHandles)
    onValueChanged(value, 'slider_1_Val', updateGuiHandles);
end

now call that from your callback function:

function edit1_Callback(hObject, eventdata, handles)
    edit1_value=get(hObject,'String');
    onSliderValueUpdated(edit1_value, {handles.slider1});
end
function slider1_Callback(hObject, eventdata, handles)    
    slider1Value = get(handles.slider1,'Value');
    onSliderValueUpdated(slider1Value, {handles.edit1});
end
