在另一个面板中有两个面板（一个是ScrolledPanel）。最下面的是 ScrolledPanel，只要我调用 ScrolledPanel 上的任何方法，例如
panel.SetScrollRate(10, 10)我刚刚发现，如果我在 InspectionTool 中添加下面的行，它就会开始工作，但如果我在实际代码中包含该行，我就不会像以前一样得到任何小部件。

我已经解决了主要问题。我必须做两件事才能让它正常工作。
首先，我在
_create_widgets wx.CallLater(100, panel.SetupScrolling, rate_x=10, rate_y=10)
其次，我必须创建一个在发生调整大小事件时运行的事件。下面的行或多或少被添加到
_panel_bot self.Bind(wx.EVT_SIZE, self.resize_closure(panel, grid_sizer))
我倾向于在调用事件时使用闭包，这样我就可以将其他变量传递到事件中。活动代码如下。
def resize_closure(self, panel, grid_sizer):
def on_size_change(event):
width, height = grid_sizer.GetSize()
if not width <= 1 or not height <= 1:
panel.SetSizeHints(width, height)
return on_size_change
这似乎解决了除一个问题之外的所有问题。我需要使用框架底部的状态栏，但是当我滚动到任何面板的底部时，最后一个小部件被状态栏部分覆盖。然而，这是一个不同的问题。
