Question

我是wxglade的新手，正在尝试创建一个表单来显示选项卡和拆分窗口。左窗格上将有树列表。问题是，当我打开表单时，它会显示树列表，但是列表无法折叠或展开。当我转到第二个选项卡并返回第一个选项卡时，树形列表显示在小框中。

import wx

# Define the tab content as classes:
class TabOne(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)



        self.SetSize((400, 300))
        self.window_1 = wx.SplitterWindow(self, wx.ID_ANY)
        self.window_1_pane_1 = wx.ScrolledWindow(self.window_1, wx.ID_ANY, style=wx.BORDER_RAISED | wx.TAB_TRAVERSAL)
        #self.button_1 = wx.Button(self.window_1_pane_1, wx.ID_ANY, "button_1")

        #t = wx.StaticText(self, -1, "This is the first tab", (100,100)) start list
        il = wx.ImageList(16,16)

        self.fldridx = il.Add(wx.ArtProvider.GetBitmap(wx.ART_FOLDER, wx.ART_OTHER, (16,16)))
        self.fldropenidx = il.Add(wx.ArtProvider.GetBitmap(wx.ART_FILE_OPEN,   wx.ART_OTHER, (16,16)))
        self.fileidx = il.Add(wx.ArtProvider.GetBitmap(wx.ART_NORMAL_FILE, wx.ART_OTHER, (16,16)))

        self.tree = wx.TreeCtrl(self, style=wx.TR_DEFAULT_STYLE | wx.TR_EDIT_LABELS)

        self.tree.AssignImageList(il)

        root = self.tree.AddRoot("Server")
        self.tree.SetItemData(root, None)
        self.tree.SetItemImage(root, self.fldridx,wx.TreeItemIcon_Normal)
        self.tree.SetItemImage(root, self.fldropenidx,wx.TreeItemIcon_Expanded)

        tree = ["A","B","C","D","E","F","G","H"]

        self.AddTreeNodes(root, tree)

        self.tree.Expand(root)



    def AddTreeNodes(self, parentItem, items):
        for item in items:
            if type(item) == str:
                newItem = self.tree.AppendItem(parentItem, item)
                self.tree.SetItemData(newItem, None)

            else:
                newItem = self.tree.AppendItem(parentItem, item[0])
                self.tree.SetItemPyData(newItem, None)
                #self.tree.SetItemImage(newItem, self.fldridx,wx.TreeItemIcon_Normal)
                self.tree.SetItemImage(newItem, self.fldropenidx,wx.TreeItemIcon_Expanded)

                self.AddTreeNodes(newItem, item[1])

wx.TreeCtrl具有内置的水平和垂直滚动条。因此，我猜这里不需要使用wx.ScrolledWindow。我将TabStripPlacement="Left"的代码简化为以下代码：

class TabOne

现在可以正常工作了。
