一.分隔窗口

# coding=utf-8
import wx

# 自定义窗口类MyFrame
class MyFrame(wx.Frame):
    def __init__(self):
        super().__init__(parent=None, title='分隔窗口', size=(350, 180))
        self.Centre()  # 设置窗口居中
        splitter = wx.SplitterWindow(self, -1)  # 直接父类上
        leftpanel = wx.Panel(splitter)
        rightpanel = wx.Panel(splitter)
        splitter.SplitVertically(leftpanel, rightpanel, 100)
        splitter.SetMinimumPaneSize(80)
        list2 = ['苹果', '橘子', '香蕉']
        lb2 = wx.ListBox(leftpanel, -1, choices=list2, style=wx.LB_SINGLE)
        self.Bind(wx.EVT_LISTBOX, self.on_listbox, lb2)
        vbox1 = wx.BoxSizer(wx.VERTICAL)
        vbox1.Add(lb2, 1, flag=wx.ALL | wx.EXPAND, border=5)
        leftpanel.SetSizer(vbox1)
        vbox2 = wx.BoxSizer(wx.VERTICAL)
        self.content = wx.StaticText(rightpanel, label='右侧面板')
        vbox2.Add(self.content, 1, flag=wx.ALL | wx.EXPAND, border=5)
        rightpanel.SetSizer(vbox2)
    def on_listbox(self, event):
        s = '选择 {0}'.format(event.GetString())
        self.content.SetLabel(s)

class App(wx.App):
    def OnInit(self):
        # 创建窗口对象
        frame = MyFrame()
        frame.Show()
        return True

if __name__ == '__main__':
    app = App()
    app.MainLoop()  # 进入主事件循环

二.使用树

# coding=utf-8
import wx

# 自定义窗口类MyFrame
class MyFrame(wx.Frame):
    def __init__(self):
        super().__init__(parent=None, title='树控件', size=(500, 400))
        self.Centre()  # 设置窗口居中
        splitter = wx.SplitterWindow(self)
        leftpanel = wx.Panel(splitter)
        rightpanel = wx.Panel(splitter)
        splitter.SplitVertically(leftpanel, rightpanel, 200)
        splitter.SetMinimumPaneSize(80)
        self.tree = self.createTreeCtrl(leftpanel)
        self.Bind(wx.EVT_TREE_SEL_CHANGING, self.on_click, self.tree)
        vbox1 = wx.BoxSizer(wx.VERTICAL)
        vbox1.Add(self.tree, 1, flag=wx.ALL | wx.EXPAND, border=5)
        leftpanel.SetSizer(vbox1)
        vbox2 = wx.BoxSizer(wx.VERTICAL)
        self.content = wx.StaticText(rightpanel, label='右侧面板')
        vbox2.Add(self.content, 1, flag=wx.ALL | wx.EXPAND, border=5)
        rightpanel.SetSizer(vbox2)
    def on_click(self, event):
        item = event.GetItem()
        self.content.SetLabel(self.tree.GetItemText(item))
    # 初始化树的方法
    def createTreeCtrl(self, parent):
        tree = wx.TreeCtrl(parent)
        items = []
        imglist = wx.ImageList(16, 16, True, 2)
        imglist.Add(wx.ArtProvider.GetBitmap(wx.ART_FOLDER, size=wx.Size(16, 16)))
        imglist.Add(wx.ArtProvider.GetBitmap(wx.ART_NORMAL_FILE, size=wx.Size(16, 16)))
        tree.AssignImageList(imglist)
        root = tree.AddRoot("TreeRoot", image=0)
        items.append(tree.AppendItem(root, "Item 1", 0))
        items.append(tree.AppendItem(root, "Item 2", 0))
        items.append(tree.AppendItem(root, "Item 3", 0))
        items.append(tree.AppendItem(root, "Item 4", 0))
        items.append(tree.AppendItem(root, "Item 5", 0))
        for ii in range(len(items)):
            id = items[ii]
            tree.AppendItem(id, "Subitem 1", 1)
            tree.AppendItem(id, "Subitem 2", 1)
            tree.AppendItem(id, "Subitem 3", 1)
            tree.AppendItem(id, "Subitem 4", 1)
            tree.AppendItem(id, "Subitem 5", 1)
        tree.Expand(root)  # 展开根下子节点
        tree.Expand(items[0])  # 展开Item 1下子节点
        tree.Expand(items[3])  # 展开Item 4下子节点
        tree.SelectItem(root)  # 选中根节点
        return tree

class App(wx.App):
    def OnInit(self):
        # 创建窗口对象
        frame = MyFrame()
        frame.Show()
        return True

if __name__ == '__main__':
    app = App()
    app.MainLoop()  # 进入主事件循环
