问题描述
我有以下GUI，该GUI是在当前位置使用空的sizer创建的。大小调整器可能是折叠的，因为它的比例为0，但是我这样画了它，所以您可以看到它。
当您单击“ + Need”按钮时，程序将创建带有一堆按钮和控件的新的定尺寸器，然后将其添加到该定尺寸器中。但是，它们没有出现在应有的位置。实际上，新的sizer及其内容已折叠，并且位于您的左上角。
显然不是我想要的。但是，当我仅通过单击并拖动边缘之一来调整窗口大小时，所有内容都会弹出到位置：
我尝试调用我可以想到的-> Layout（）和-> Fit（）的每种组合，但我无法使其正常工作。这是在程序加载时创建GUI的代码，由框架构造函数调用。它创建“ needs_sizer_wrap”，它是BoxSizer，开始为空，单击按钮时将新的动态尺寸调整器添加到其中。注意，在图像中它显示为“ needsSizerWrap”，但代码实际上是“ needs_sizer_wrap”

解决方法
直到现在我才意识到这一点，但是根据文档，当您在top level window上调用Layout
时，使用窗口大小调整器布置子项或调整唯一子项的大小 覆盖整个窗口的面积。
此类重写基类Layout（）方法以检查是否 窗口中恰好包含一个孩子-通常是这样， wxPanel通常被创建为wxTopLevelWindow的唯一子项– 如果是这种情况，请调整此子窗口的大小以覆盖 整个客户区。
所以我猜想在只有1个子窗口的框架上调用Layout是行不通的，因为该调用只会尝试调整面板的大小，但是面板不会更改尺寸，因此不会尝试重新布局其新的子窗口
似乎起作用的是添加类似的内容
this->main_panel->Layout();
到MullSimple_2Frame::addNeedGUI()的末尾。这样会在面板上而不是框架上重新布局。
或者，根据文档，您可以仅使用调整大小的框架，并仅向其添加main_panel。但是，正如我在另一个答案中所说的那样，通常只有一个窗口的尺寸调整器没有多大意义。
