콜백을 사용할 때 GUI 핸들 업데이트

Question

GUIDE로 GUI를 만들었으므로 콜백에서 콜백을 호출 할 때 GUI 핸들을 업데이트하는 방법을 알 수 없습니다. 그래서 함수를 호출하는 기능의 예를 들어 내가 가진 모든는 다음과 같다 :

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

% Hints: get(hObject,'String') returns contents of start_ss as text 
%  str2double(get(hObject,'String')) returns contents of start_ss as a double 
start_hh_Callback(hObject, eventdata, handles) 

및 start_hh_Callback에 나는 코드가 아래에 주어진하지만 난 guidata(hObject, handles)을 가지고 내 handles.plot_holds에 관계없이 사실을 업데이트하지 않습니다 있습니다. 내가 이것을 함수로 사용하고 있기 때문에 이것인가? 방금 start_hh_Callback을 거치지 않고 start_ss_Callback을 통하지 않으면 업데이트됩니다. 그러나 start_ss_Callback과 같은 콜백 내에서 사용하면 업데이트되지 않습니다.

제 질문이 명확히되기를 바랍니다. 설명이 필요한 경우 알려 주시기 바랍니다.

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

% Hints: get(hObject,'String') returns contents of start_hh as text 
%  str2double(get(hObject,'String')) returns contents of start_hh as a double

guidata(hObject, handles); 

Answer 1

당신은 어떤 핸들 - 수정 기능을 한 후, 다시 핸들을로드해야합니다

: 당신이 콜백의

% this modifies and writes the handles to the guidata 
start_hh_Callback(hObject, eventdata, handles); 
% now read back the updated value 
handles = guidata(hObject); 

은 또한 당신은 또한 handles 반환 값을 만들 수 있습니다. 보통 이것은 콜백으로 실제로 사용될 때 무시되며 "보통"함수로 사용될 때 guidata에서 다시 읽을 필요가 없습니다. 코드는 다음과 같을 수 있습니다 : 콜백와

handles = start_hh_Callback(hObject, eventdata, handles); 

가로 다시 정의 :

function [handles] = start_hh_Callback(hObject, eventdata, handles) 
... 
end
