Titel: Variable wird nicht erkannt
Ich möchte eine Variable, die durch ein Textfeld im GUI eingegeben wird, weiter verwenden um etwas zu berechnen. Leider komtt dabei immer der Fehler, das die variable nicht bekannt ist.
Hier der code:
Code:
functionvarargout = Top_Load_1(varargin) % TOP_LOAD_1 M-file for Top_Load_1.fig % TOP_LOAD_1, by itself, creates a new TOP_LOAD_1 or raises the existing % singleton*.
%
% H = TOP_LOAD_1 returns the handle to a new TOP_LOAD_1 or the handle to % the existing singleton*.
%
% TOP_LOAD_1('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in TOP_LOAD_1.M with the given input arguments.
%
% TOP_LOAD_1('Property','Value',...) creates a new TOP_LOAD_1 or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before Top_Load_1_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to Top_Load_1_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES
% Edit the above text to modify the response to help Top_Load_1

kannst du vielleicht nochmal den Callback rauskopieren, um den es geht? Ohne fig-File ist das ganze ja nicht lauffähig, und durch den ganzen Code durchzugehen ist doch etwas mühsam.

Die Definitionen für ein GUI verstehe ich noch nicht ganz.
Hat jemand ein laufähiges Beispiel mit einem GUI?
Ein Wert soll eingetragen werden, danach wir etwas berechnet und anschliessend das Resultat im GUI wieder dargestellt.
bitte schreib doch die Fehlermeldung dazu. Hellsehen ist leider nicht meine Stärke Oder doch?? Bei handle fehlt ein s. Da hätte man nun auch selber draufkommen können, oder?
Sorry war mein Fehler es scheint wirklich zu funktionieren. Nicht für Ungutes. Danke für die Hilfe
