为什么 Treebook 中的 ScrolledPanel 不会自动调整大小？

Question

因为我需要滚动条，所以我通过 ScrolledPanel 更改了默认面板，但我在 ScrolledPanel 中插入的内容不会根据窗口大小自动调整大小。

然后我尝试创建一个默认面板并通过 BoxSizer 将所有小部件插入其中，最后通过另一个 BoxSizer 将此面板插入到 ScrolledPanel 中，但内容继续进行而不进行自动调整大小。

我也尝试了相反的方法，即我创建了一个标准面板并使用 BoxSizer 插入到我的 ScrolledPanel 中，但也没有用。

另一个细节是这个 ScrolledPanel 必须在 TreeBook 中，因为我有一个树来管理每个 ScrolledPanel 的调用。

我的代码：

    instance = None

我想要的是单击树中的一个项目并在面板旁边打开，其中内容根据我的窗口大小（静态文本、静态线）调整大小。

Answer 1

我不确定我是否理解正确，但是：

• StaticText 不会自动换行，因此即使正确调整“内部面板”的大小，文本也不会可见。您可能想要使用某种 TextCtrl，可能是富文本 ctrl。
• 如果你有一个滚动面板，那么面板内部有它需要的任何大小，滚动面板只是添加滚动条。

因此，您需要的是：在 MenuPanel 中创建另一个面板，并将 MenuPanel 中的所有小部件创建为这个新面板的子级。然后为 MenuPanel 添加一个 on-size 处理程序

    self.Bind(wx.EVT_SIZE, self.OnSize)

def OnSize(self, evt):
    evt.Skip(False)
    self.p.SetSize(evt.GetSize())

（self.p 是 MenuPanel 中的新面板）。但这会设置面板的大小，因此不需要滚动条。您可能只需要垂直滚动条，并且仅在需要时才需要，对吗？那么我可能只会在可能的情况下尝试设置窗口的宽度，或者设置宽度和非常大的高度，测量并再次设置大小。
