单击工具栏中的按钮时无法动态更改文本（wxpython）

Question

我对 wxPython 库不是很有经验，目前正在开发一个使用工具栏和事件处理的个人投资组合应用程序。但是，当我单击工具栏中的按钮时，文本并没有像我预期的那样动态变化。我不确定我可能犯了什么错误。目前我只包含了个人信息部分的事件处理方法。如果有人有使用 wxPython 创建应用程序的经验，我将非常感谢你帮助解决这个问题。

我当前的代码：

import wx


class MyPortfolio(wx.Frame):
    def __init__(self):
        super().__init__(None, title="Krishnan\'s Portfolio", size=(800, 600))

        self.panel = wx.Panel(self)

        self.create_toolbar()
        self.create_menu()

        self.Bind(wx.EVT_TOOL, self.on_toolbar_click)
        self.Bind(wx.EVT_MENU, self.on_menu_click)

        self.Show()

    def create_toolbar(self):
        toolbar = self.CreateToolBar()
        toolbar.AddTool(1, 'Personal Info', wx.Bitmap('icons/personal.png'))
        toolbar.AddTool(2, 'Education', wx.Bitmap('icons/education.png'))
        toolbar.AddTool(3, 'Work Experience', wx.Bitmap('icons/work.png'))
        toolbar.AddTool(4, 'Skills', wx.Bitmap('icons/skills.png'))
        toolbar.AddTool(5, 'Projects', wx.Bitmap('icons/projects.png'))
        toolbar.Realize()

    def create_menu(self):
        menubar = wx.MenuBar()
        file_menu = wx.Menu()

你没有得到工具栏事件，因为你绑定了自己。

将工具栏更改为

self.toolbar

并绑定到它，即

（请原谅位图）

    self.toolbar.Bind(wx.EVT_TOOL, self.on_toolbar_click)
    self.Bind(wx.EVT_MENU, self.on_menu_click)

    self.Show()

def create_toolbar(self):
    self.toolbar = self.CreateToolBar()
    self.toolbar.AddTool(1, 'Personal Info', wx.Bitmap('stop.png'))
    self.toolbar.AddTool(2, 'Education', wx.Bitmap('stop.png'))
    self.toolbar.AddTool(3, 'Work Experience', wx.Bitmap('stop.png'))
    self.toolbar.AddTool(4, 'Skills', wx.Bitmap('stop.png'))
    self.toolbar.AddTool(5, 'Projects', wx.Bitmap('stop.png'))
    self.toolbar.Realize()
