wxPython Window and Dialog Tutorial with Complete Code Samples

This article provides a comprehensive guide to creating various wxPython GUI elements—including basic Frame windows, frames with toolbars and status bars, MDI and MiniFrame windows, a range of dialogs (about, message, text entry, file, font, color), and clipboard operations—accompanied by explanatory text, screenshots, and full Python code examples.

Basic Frame window

#!/usr/bin/python
# -*- coding: UTF-8 -*-
import wx

class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, -1, u'自定义窗口', size=(300, 100))  # call parent initializer

if __name__ == '__main__':
    app = wx.PySimpleApp()
    myFrame = MyFrame()
    myFrame.Show()
    app.MainLoop()

Frame with toolbar and status bar

#!/usr/bin/python
# -*- coding: UTF-8 -*-
import wx

class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, -1, u'自定义窗口', size=(300, 200))
        # load toolbar icons
        png_save = wx.Image('./icons/save_page.png', wx.BITMAP_TYPE_PNG).ConvertToBitmap()
        png_home = wx.Image('./icons/go_home.png', wx.BITMAP_TYPE_PNG).ConvertToBitmap()
        png_cfg  = wx.Image('./icons/settings.png', wx.BITMAP_TYPE_PNG).ConvertToBitmap()
        png_forward = wx.Image('./icons/go_forward.png', wx.BITMAP_TYPE_PNG).ConvertToBitmap()
        png_back = wx.Image('./icons/go_back.png', wx.BITMAP_TYPE_PNG).ConvertToBitmap()
        toolbar = self.CreateToolBar(wx.TB_HORIZONTAL | wx.TB_TEXT)
        toolbar.AddSimpleTool(100, png_save, "Save page")
        toolbar.AddSimpleTool(200, png_home, "Go home")
        toolbar.AddSimpleTool(220, png_back, "Go back")
        toolbar.AddSimpleTool(230, png_forward, "Go Forward")
        toolbar.AddSimpleTool(400, png_cfg, "Settings")
        toolbar.Realize()
        self.CreateStatusBar()

if __name__ == '__main__':
    app = wx.PySimpleApp()
    myFrame = MyFrame()
    myFrame.Show()
    app.MainLoop()

MDI (Multiple Document Interface) window

#!/usr/bin/python
# -*- coding: UTF-8 -*-
import wx

class MDIFrame(wx.MDIParentFrame):
    def __init__(self):
        wx.MDIParentFrame.__init__(self, None, -1, u"MDI窗口", size=(300,200))
        menubar = wx.MenuBar()
        menu = wx.Menu()
        menu.Append(5000, u"新建(&N)")
        menu.Append(5001, u"退出(&X)")
        menubar.Append(menu, u"文件(&F)")
        self.SetMenuBar(menubar)
        self.Bind(wx.EVT_MENU, self.OnNewWindow, id=5000)
        self.Bind(wx.EVT_MENU, self.OnExit, id=5001)

    def OnExit(self, evt):
        self.Close(True)

    def OnNewWindow(self, evt):
        win = wx.MDIChildFrame(self, -1, u"子窗口")
        win.Show(True)

if __name__ == '__main__':
    app = wx.PySimpleApp()
    frame = MDIFrame()
    frame.Show()
    app.MainLoop()

MiniFrame (non‑resizable window)

#!/usr/bin/python
# -*- coding: UTF-8 -*-
import wx

class MiniFrame(wx.MiniFrame):
    def __init__(self):
        wx.MiniFrame.__init__(self, None, -1, u'不能最小化和最大化的窗口', pos=(100,100), size=(300,200), style=wx.DEFAULT_FRAME_STYLE | wx.CLOSE_BOX)
        panel = wx.Panel(self, -1, size=(300,200))

if __name__ == '__main__':
    app = wx.PySimpleApp()
    frame = MiniFrame()
    frame.Show()
    app.MainLoop()

Dialog examples (about dialog, message dialog, text entry dialog, file dialog)

#!/usr/bin/python
# -*- coding: UTF-8 -*-
import wx

class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, -1, u"自定义对话框", size=(300,200))
        menuHelp = wx.Menu()
        aboutItem = menuHelp.Append(-1, u"关于(&A)")
        menuBar = wx.MenuBar()
        menuBar.Append(menuHelp, u"帮助(&H)")
        self.SetMenuBar(menuBar)
        self.Bind(wx.EVT_MENU, self.ShowAboutDlg, aboutItem)

    def ShowAboutDlg(self, event):
        dlg = MyDialog(self, -1, u"关于")
        dlg.ShowModal()
        dlg.Destroy()

class MyDialog(wx.Dialog):
    def __init__(self, parent, id, title):
        wx.Dialog.__init__(self, parent, id, title, size=(100,100))
        panel = wx.Panel(self)
        okBtn = wx.Button(self, wx.ID_OK, u"确定")
        okBtn.Bind(wx.EVT_BUTTON, self.CloseDlg)
        self.Show()

    def CloseDlg(self, event):
        self.Close()

if __name__ == '__main__':
    app = wx.PySimpleApp()
    frame = MyFrame()
    frame.Show()
    app.MainLoop()

Clipboard operations

#!/usr/bin/python
# -*- coding: UTF-8 -*-
import wx
from wx import xrc

class MyApp(wx.App):
    def OnInit(self):
        self.res = xrc.XmlResource('clipboard.xrc')
        self.init_frame()
        return True

    def init_frame(self):
        self.frame = self.res.LoadFrame(None, 'MyFrame2')
        self.panel = xrc.XRCCTRL(self.frame, 'm_Panel1')
        self.text1 = xrc.XRCCTRL(self.panel, 'm_textCtrl4')
        self.text2 = xrc.XRCCTRL(self.panel, 'm_textCtrl5')
        self.frame.Bind(wx.EVT_BUTTON, self.OnCopy, id=xrc.XRCID('m_button6'))
        self.frame.Bind(wx.EVT_BUTTON, self.OnPaste, id=xrc.XRCID('m_button7'))
        self.frame.Bind(wx.EVT_BUTTON, self.OnQuit, id=xrc.XRCID('m_button8'))
        self.frame.Show()

    def OnCopy(self, event):
        data = wx.TextDataObject()
        data.SetText(self.text1.GetValue())
        if wx.TheClipboard.Open():
            wx.TheClipboard.SetData(data)
            wx.TheClipboard.Close()
        else:
            wx.MessageBox('不能打开剪贴板', '错误')

    def OnPaste(self, event):
        data = wx.TextDataObject()
        success = False
        if wx.TheClipboard.Open():
            success = wx.TheClipboard.GetData(data)
            wx.TheClipboard.Close()
        else:
            wx.MessageBox('不能打开剪贴板', '错误')
        if success:
            self.text2.SetValue(data.GetText())
        else:
            wx.MessageBox('格式不匹配', '错误')

    def OnQuit(self, event):
        self.frame.Close(True)

if __name__ == '__main__':
    app = MyApp(False)
    app.MainLoop()
