Question

我的keypressfcn有点问题。如果用户在edittextbox中键入内容，我想从另一个m文件中启动一个函数，如果他们按下回车键。

实际上它看起来像这样：

% --- Executes on key press with focus on ET_variabelpos_9 and none of its controls.
function ET_variabelpos_9_KeyPressFcn(hObject, eventdata, handles)
% hObject    handle to ET_variabelpos_9 (see GCBO)
% eventdata  structure with the following fields (see UICONTROL)
%   Key: name of the key that was pressed, in lower case
%   Character: character interpretation of the key(s) that was pressed
%   Modifier: name(s) of the modifier key(s) (i.e., control, shift) pressed
% handles    structure with handles and user data (see GUIDATA)

%Modifier um zu überprüfen, ob die Pfeiltastengedrückt wurden
val=double(get(gcf,'CurrentCharacter'))

%28 => leftArrow
%29 => rightArrow
%30 => upArrow
%31 => downArrow


if val == 30
    sw1 = get(handles.ET_variabelpos_9,'String')
    %Relative Position anfahren (Hoch)
    gotorelativ_up_function(sw1,0,8);

elseif val == 31
    sw1 = get(handles.ET_variabelpos_9,'String')
    %Relative Position anfahren (Hoch)
    gotorelativ_down_function(sw1,0,8);
end

我从EditText中读取了值并将其传输到函数gotorelativ_down_function或gotorelativ_up_function。

它工作正常，唯一的问题是，用户需要按两次输入才能获得edittext的当前值。

我已经解决了。我使用了错误的功能。代码应该用在编辑文本的回调函数中。

在输入时从EditText获取值
