Matlab GUI 设计光学效果（过渡）

Question

我设计了一个带有 uitabs 的 GUI。我想在更改所选选项卡时实现平滑过渡（光学效果）。为此，我编写了以下回调：

function SelectionChangeCbk(src,evt) 
  oldTab = evt.OldValue;
  newTab = evt.NewValue;
  set([oldTab,newTab],'Visible','off');
  drawnow;
  pause(2);
  set(newTab,'Visible','on');


  end

但是，我可以获得我的目标，因为这不起作用（我有两个选项卡。更改之前选择的选项卡称为 oldTab，更改后选择的新选项卡称为 newTab。我希望在更改时从 oldTab 到 newTab，首先 oldTab 和 newTab 变得不可见，然后等待两秒钟，newTab 才出现）。

我已经尝试过WindowAPI 应用程序，但它只适用于图形句柄。

P.D.：这是完整的代码：

Answer 1

我不会使用uitabgroup。它没有被记录，它的行为是未定义的。相反，请考虑使用 Matlab Central 中的 GUI Layout toolbox 包。顺便说一句，可见性是通过将面板移动到屏幕上看不到的较远位置来处理的（如 (-100000,-100000) ） - 它似乎比设置可见性更强大。

无论如何，没有简单的方法可以在 Matlab GUI 中实现平滑的淡入/淡出过渡，至少没有文档记录。
