Question

我想用MATLAB用户界面创建一个日期时间向量，到目前为止我已经创建了所有编辑框和按钮，它们工作正常，但我面临着两个小问题

1）pushbutton_cb3函数仅在我按下日期输入时才从编辑骨骼中检索日期字符串，我该如何删除？ 2）我想函数pushbutton_cb3返回我在代码中提到的某个值，函数waitfor看起来很不错但我不知道如何在这里使用它帮助将受到高度赞赏

Answer 1

我没有金融工具箱，所以让我在我的例子中考虑我手动输入字段中的日期（我检查以确保输入与uicalendar相同的字符串）。

您可以使用waitfor代替uiwait。这样，只有当例外变量被更改时，应用程序才会继续（在我的例子中，我将数据放在ButtonHandle3.UserData

中

function [returnedVector] = AddClassCalender

f = figure('Name', 'AddClassCalender');

EditBoxHandle1 = uicontrol(f, 'Style', 'Edit','Tag','edit1',... 
    'Units','normalized','Position', [0.05 0.9 0.2 0.05], 'Callback',@edit_callback);
EditBoxHandle2 = uicontrol(f, 'Style', 'Edit','Tag','edit2', ...
    'Units','normalized','Position', [0.3 0.9 0.2 0.05], 'Callback',@edit_callback2);
ButtonHandle1 = uicontrol(f, 'Style', 'PushButton', ...
    'String', 'Select the starting date', ...
    'Units','normalized','Position', [0.05 0.85 0.22 0.05], ...
    'callback', @pushbutton_cb1);
ButtonHandle2 = uicontrol(f, 'Style', 'PushButton', ...
    'String', 'Select the starting date', ...
    'Units','normalized','Position', [0.3 0.85 0.22 0.05], ...
    'callback', @pushbutton_cb2);
TextHandle = uicontrol(f, 'Style', 'Text', ...
    'String', 'Interval(mins):', ...
    'Horizontalalignment', 'left', ...
    'Units','normalized','Position', [0.6 0.9 0.2 0.05]);
EditBoxHandle3 = uicontrol(f, 'Style', 'Edit','Tag','edit3', ...
    'Units','normalized','Position', [0.7 0.9 0.2 0.05], 'Callback',@edit_callback3);
ButtonHandle3 = uicontrol(f, 'Style', 'PushButton', ...
    'String', 'Generate', ...
    'Units','normalized','Position', [0.7 0.85 0.2 0.05], ...
    'callback', @pushbutton_cb3);

%% I WANT THE PUSHBUTTON TO RETURN THE DATETIME VECTOR HERE SO I CAN USE IT FURTHER MORE 
waitfor(ButtonHandle3, 'UserData')

% Do what you want with the data here, I choose to return it and to close the figure;
returnedVector = ButtonHandle3.UserData;
delete(f);


    function pushbutton_cb1(hcbo, eventStruct)
        uicalendar('Weekend', [1 0 0 0 0 0 1], ...
            'SelectionType', 1, ...
            'DestinationUI', EditBoxHandle1);
    end
    function pushbutton_cb2(hcbo, eventStruct)
        uicalendar('Weekend', [1 0 0 0 0 0 1], ...
            'SelectionType', 1, ...
            'DestinationUI', EditBoxHandle2);
    end
    function edit_callback(hcbo, eventStruct)
       Date = hcbo.String;
       hcbo.UserData  = Date;
    end
    function edit_callback2(hcbo, eventStruct)
       Date = hcbo.String;
       hcbo.UserData  = Date
    end
    function edit_callback3(hcbo, eventStruct)
       Interval = hcbo.String;
       hcbo.UserData  = Interval
    end


    function pushbutton_cb3(hcbo, eventStruct)
        date1 = findobj('Tag','edit1');
        date2 = findobj('Tag','edit2');
        interval = findobj('Tag','edit3');
        data1 = date1.UserData;
        data2 = date2.UserData;
        int_str = interval.UserData;
        interv = str2num(int_str);
        interval_cal = 1/(1440/interv);
        datevector = datetime(data1,'Format','dd-MMM-yyyy HH:mm:ss'):interval_cal:datetime(data2);
        % I set the returned data in UserData in order to finish the waitfor
        hcbo.UserData = datevector;
    end

end

仅在调用回调函数时生成向量
