MATLAB GUI 中的多个回调

Question

我正在尝试将字符向量回调转换为函数句柄。但是，我正在调用多个回调，我认为我可以创建一个带有匿名函数的元胞数组？

代码如下：

guiel.hPB(2)=uicontrol(guiel.cPanel(2),'Style','PushButton','Units','pixels',...
        'TooltipString',guiel.plotTt,...
        'Position',[cnst.bhspace 3*cnst.bvspace+2*cnst.bheight cnst.bwidth cnst.bheight],...
        'String','Run Simulation','fontsize',10,'FontWeight','Demi',...
        'CallBack','eval(codeblk.CLOSE_MDL_FCN); set(guiel.cPanel(4),''Visible'',''off'');set(guiel.APPWINDOW,''Resize'',''off''); primePlot;',...
        'Enable','off');

我想做的是将codeblk.CLOSE_MDL_FCN写入函数句柄，其余的是匿名函数句柄？但是，我不确定该怎么做。

codeblk.CLOSE_MDL_FCN = ['if  ~isempty(find_system(''Name'',vars.simfilename))'...
                     'vars.simtime = str2num(get_param(vars.simfilename,''StopTime''));'...
                     'set(guiel.hSimtime,''String'',num2str(vars.simtime));'...
                     'save_system(vars.simfilename);'...
                     'close_system(vars.simfilename);'...
                     'end'];

Answer 1

creating a callback using a function handle is that it is a single function to handle everything for when that GUI object is interacted with. Using a cell array callback 的想法是当您需要向函数传递额外数据时，而不是为了调用多个函数。以下是我建议您设计按钮回调的方式：

guiel.hPB(2) = uicontrol(..., 'CallBack', @callback_hPB2, ...);

然后你会定义两个 nested functions:

function callback_hPB2(~, ~)
  close_fcn();
  set(guiel.cPanel(4), 'Visible', 'off');
  set(guiel.APPWINDOW, 'Resize', 'off');
  primePlot();
end

function close_fcn
  if ~isempty(find_system('Name', vars.simfilename))
    vars.simtime = str2num(get_param(vars.simfilename, 'StopTime'));
    set(guiel.hSimtime, 'String', num2str(vars.simtime));
    save_system(vars.simfilename);
    close_system(vars.simfilename);
  end
end
