为什么树电子书中的滚动面板不能自动调整大小？

当我需要滚动条时，我用一个ScrolledPanel更改了默认面板，但是我在ScrolledPanel中插入的内容并不能使它根据窗口的大小自动调整大小。你知道吗

然后，我尝试创建一个默认面板，并通过一个BoxSizer插入其中的所有小部件，最后通过另一个BoxSizer将这个面板插入到ScrolledPanel中，但是内容没有自动调整大小就继续了。你知道吗

我也尝试了相反的方法，也就是说，我创建了一个标准面板，并使用BoxSizers插入到我的scrolled面板中，但也没有起作用。你知道吗

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

我的代码：

import wx
import wx.lib.scrolledpanel as scrolled

from gettext import gettext as _

class MyMainView(wx.Frame):

    instance = None
    init = 0

    def __init__(self, app):
        if self.init:
            return

        self.frameWidth = 850
        self.frameHeight = 600
        self.init = 1

        no_sys_menu = wx.MINIMIZE_BOX | wx.MAXIMIZE_BOX | wx.CAPTION | wx.CLIP_CHILDREN | wx.CLOSE_BOX
        wx.Frame.__init__(self, None, title=_("Title"), style=no_sys_menu)

        sizer.Add(treeBook, 1, wx.ALL | wx.EXPAND, 10)

我想要的是单击树中的一个项目，然后在一个面板旁边打开，其中的内容将根据我的窗口大小（statictexts，staticlines）调整大小。你知道吗

我不确定我是否理解正确，但是：

  • 静态文本不会自动断线，因此即使“内部面板”的大小调整正确，文本也不会可见。您可能需要使用某种TextCtrl，可能是一个富文本ctrl。你知道吗
  • 如果你有一个滚动面板，那么面板的内部有它需要的任何大小，滚动面板只是添加滚动条。你知道吗

因此，您需要的是：在MenuPanel中创建另一个面板，并在这个新面板的MenuPanel子级中创建所有小部件。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是菜单面板中的新面板）。但这会设置面板的大小，因此不需要滚动条。你可能只想要垂直滚动条，而且只在需要的时候，对吧？如果可能的话，我可能会尝试设置窗口的宽度，或者设置宽度和非常大的高度，测量，然后再次设置大小。你知道吗
