wxpython教程手写wxpython会有各种问题，可以去下载 wxformbuilder布局管理器然后去百度一下这个布局管理器的教程，这里太多了不多赘述。两种创建窗口方式：class MyFrame(wx.Frame)和class MyPanel(wx.Panel)来继承wx.Frame和wx.Panel，但是用wxformbuilder来创建布局和窗口会自动帮忙写好。继承wx.Frame的结尾是 app=wx.App() frm=MyFrame() frm.Show() app.MainLoop() Show中的参数为True/False，False则不可见窗口继承wx.Panel的结尾是 app = wx.App() frame = wx.Frame(None) panel = MyPanel(frame) frame.Show() app.MainLoop() MainLoop为每个继承类都要填写，否则无法运行基本的控件TextCtrl，Button，StaticText TextCtrl 基本的属性Clear()（清空TextCtrl中的内容）,AppendText()（在末尾添加文本）排列布局在wxformbuilder中都有举几个列子（wx.TE_MULTILNE为可以进行多行输入，wx.TE_LEFT为左对齐，可以用 |

20183215 2019-2020-2 《Python程序设计》实验三报告课程：《Python程序设计》班级： 1832 姓名：董振龙学号： 20183215 实验教师：王志强实验日期：2020年5月16日必修/选修：公选课 1.实验内容 1．创建服务端和客户端，选择一个通信端口，用Python语言编程实现通信演示程序； 2．要求包含文件的基本操作，例如打开和读写操作。 3．要求发送方从文件读取内容，加密后并传输；接收方收到密文并解密，保存在文件中。 4．程序代码托管到码云。 2. 实验过程及结果实验开始之前，我设想了一下实验结束后的效果，总觉得光秃秃的控制台缺乏美感（尽管是pycharm），于是，我打算加入GUI图形界面，既然追求美感，就贯彻到底咯。首先，我打开了一个软件： wxFormBuilder （这里我参考了一个大佬的博客），打开后的界面是这样的：我们先选择Forms点击Frame，然后再建立几个boxsizer，加入一些必备控件textctrl、button，如图，其中，设置bsizer5的proportion为9，使其看上去更加和谐最后进行一些细节上的设置，例如按钮名称以及事件绑定。最终效果如图：其中三个按钮分别绑定事件：保存之后可以导出对应的 .py文件，基本重复上述操作，可以得到客户端的图形界面和对应的 .py文件

最近对Python的开发又来了兴趣，对于Python的开发一直停留在一个表面层的认识。 Python的入手简单，语法让人爱不释手，在网络通信方面自带有成熟的类库，还有第三方开发的开源包。在GUI的开发上，Python自身带有TKinter库，还有第三方的库 (比如wxPython, Qt)等等，今天就来简单介绍下wxPython开发的环境搭建。 wxPython是一个Python包装wxWidgets（这是用 C++ 编写），一个流行的跨平台GUI工具包。由Robin Dunn以及Harri Pasanen开发，wxPython是作为一个Python扩展模块。就像wxWidgets，wxPython也是一个免费的软件。可以从官方网站下载它。在wxPython API主要模块包括一个核心模块。它由 wxObject 类，这是基础 API 的所有类。控制模块包含了所有 GUI 应用程序开发中使用的部件，例如，wx.Button，wx.StaticText（类似于一个标签），wx.TextCtrl（可编辑的文本控制）等。 wxPython 的API有GDI（图形设备接口）模块。这是一组用于在部件中的绘图类。如字体，颜色，画笔等类就是其中的一部分。所有的容器窗口类是由 Windows 模块定义。 wxPython 官方网站也主持 Phoenix 工程计划 – 为Python3.*

How to write wxPython textCtrl focus event

阅读更多关于 How to write wxPython textCtrl focus event

问题 I'm trying to fire a line of code when the user clicks on a textCtrl. The end goal is to highlight the contents of the box when it is clicked on. I am aware that this is possible with wx.EVT_SET_FOCUS, but it's either buggy or I'm implementing it wrong. Here's my code: self.m_textCtrl1 = wx.TextCtrl(self.m_panel2, wx.ID_ANY, wx.EmptyString, wx.DefaultPosition, wx.Size(100,-1), wx.TE_LEFT) self.m_textCtrl1.SetMaxLength(8) self.m_textCtrl1.SetMinSize(wx.Size(100,-1)) self.m_textCtrl1.SetMaxSize

问题 Working with wxFormBuilder under windows 7, Is there any way to set my main wxFrame to a fixed size avoiding resizing? Thanks 回答1: I don't know how to do it specifically with wxFB, but you need to remove the wxRESIZE_BORDER style from your frame. As it is used by default, you may need to explicitly specify the flags you do want to use, e.g. wxDEFAULT_FRAME_STYLE & ~(wxRESIZE_BORDER | wxMAXIMIZE_BOX) . 回答2: Yes, you can avoid a wxFrame resizng in wxFormBuilder by simple specifying you frame
