GUI：Struct contents reference from a non-struct array object.

Question

0 个投票

I cannot display the result on the editable module like "edit1".

I only list core sentences in my GUI function named untitled1, and with this function, I want to display a string on the "edit1" when I push the button "pushbutton1"

function varargout = untitled1(varargin)
gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                 'gui_Singleton',  gui_Singleton, ...
                 'gui_OpeningFcn', @untitled1_OpeningFcn, ...
                 'gui_OutputFcn',  @untitled1_OutputFcn, ...
                 'gui_LayoutFcn',  [] , ...
                 'gui_Callback',   []);
if nargin && ischar(varargin{1})
  gui_State.gui_Callback = str2func(varargin{1});
end
if nargout
  [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
  gui_mainfcn(gui_State, varargin{:});
end
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
function untitled1_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
guidata(hObject, handles);
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
function varargout = untitled1_OutputFcn(hObject, eventdata, handles) 
varargout{1} = handles.output;
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
function pushbutton1_Callback(hObject, eventdata, handles)
set(handles.edit1,'string','r')
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
function edit1_Callback(hObject, eventdata, handles)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
function edit1_CreateFcn(hObject, eventdata, handles)
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
  set(hObject,'BackgroundColor','white');
end

The problem is： Struct contents reference from a non-struct array object.

Error in untitled1>pushbutton1_Callback (line 81) set(handles.edit1,'string','r')"

Also it sometimes occurs "Reference to non-existent field 'edit1'."

you have the edit box 'edit1' in the GUI right? because, other than that, your code looks completely fine.

Please post the complete error message. While it is clear where the "edit1" problem occurres, we cannot guess the source of the "reference from a non-struct array object" error.
