Hallo folgende Fehlermeldung erhalte ich nachdem ich meine .fig getestet habe.

Undefined function or variable 'hObject'.

Dot indexing is not supported for variables of this type.

Error in fourier_synthi>pushbutton1_Callback (line 82)
set(handles.slider3,'Value',0);




Hier der Code:

Code:


function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

set(handles.slider3,'Value',0);
set(handles.slider4,'Value',0);
set(handles.slider5,'Value',0);
set(handles.slider6,'Value',0);
set(handles.slider7,'Value',0);
set(handles.slider8,'Value',0);
set(handles.slider9,'Value',0);
set(handles.slider10,'Value',0);
set(handles.slider11,'Value',0);
set(handles.slider12,'Value',0);




Der Pushbuttton soll die Values der Slider auf 0 resetten.
Wo ist der Fehler?

Hallo,

es scheinen zwei Fehlermeldungen zu sein. Die erste passt m.E. nicht zum Code, und die zweite deutet darauf hin, dass in einem anderen Teil des Codes versehentlich handles zerschossen wurde.

Grüße,
Harald

Habe das ganze nochmal neu generiert und es kommt immer noch derselbe fehler.


Bekomme diese Fehlermeldung:

Dot indexing is not supported for variables of this type.

Error in fourier_synthi>edit1_Callback (line 92)

%      singleton*.
%
%      H = FOURIER_SYNTHI returns the handle to a new FOURIER_SYNTHI or the handle to
%      the existing singleton*.
%
%      FOURIER_SYNTHI('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in FOURIER_SYNTHI.M with the given input arguments.
%
%      FOURIER_SYNTHI('Property','Value',...) creates a new FOURIER_SYNTHI or raises the

Hallo,

auf Anhieb sehe ich kein Problem.
Du führst schon wirklich die .m-Datei aus und nicht etwa die .fig-Datei direkt? Diese ist nämlich nicht dafür gedacht.

Grüße,
Harald

Hallo,

meine Empfehlung wäre, auf App Designer umzusteigen.
Frischer in der Optik, übersichtlicher, und ein Problem wie dieses könnte gar nicht passieren.

Vielen Dank für den Tipp.

Für die Uniaufgaben muss ich guide benutzen.

Aber für meine eigenen kleinen Projekte werde ich mir den App Designer mal anschauen.

Hallo,

Zitat:

Sprich doch mal den Zuständigen darauf an. Am Ende ist er sich gar nicht bewusst, dass es jetzt App Designer gibt.
