wxpython如何引用

wxPython是一个用于创建桌面应用程序的跨平台工具包，它允许开发者使用Python编写图形用户界面（GUI）程序，wxPython基于C++库wxWidgets，因此具有很好的性能和兼容性，在本教程中，我们将详细介绍如何在Python项目中引用wxPython库，并创建一个简单的桌面应用程序。

1、安装wxPython

我们需要在计算机上安装wxPython库，可以通过以下命令安装：

pip install wxPython

2、创建一个新项目

接下来，我们创建一个新的Python项目，在项目文件夹中，创建一个名为main.py的文件，这将是我们的主程序文件。

3、导入wxPython库

在main.py文件中，我们需要导入wxPython库，可以通过以下代码导入：

import wx

4、创建一个应用程序对象

要创建一个wxPython应用程序，我们需要创建一个应用程序对象，通过以下代码创建一个应用程序对象：

app = wx.App()

5、创建一个框架（窗口）对象

接下来，我们需要创建一个框架（窗口）对象，通过以下代码创建一个框架对象：

frame = wx.Frame(None, title="Hello, wxPython!")

6、显示框架（窗口）

现在，我们需要显示框架（窗口），通过以下代码显示框架（窗口）：

frame.Show()

7、运行应用程序事件循环

为了确保应用程序正常运行，我们需要运行应用程序的事件循环，通过以下代码运行事件循环：

app.MainLoop()

将以上代码整合到main.py文件中，完整的代码如下：

import wx
app = wx.App()
frame = wx.Frame(None, title="Hello, wxPython!")
frame.Show()
app.MainLoop()

8、运行程序

保存main.py文件，然后在命令行中导航到项目文件夹，通过以下命令运行程序：

python main.py

现在，你应该看到一个包含标题为“Hello, wxPython!”的简单窗口，这就是如何使用wxPython库创建一个简单的桌面应用程序，接下来，我们将介绍如何向窗口中添加控件，如按钮、文本框等。

9、添加控件到窗口

要向窗口中添加控件，我们需要使用wx.Panel类，在main.py文件中导入wx.Panel类：

from wx import Panel, Button, TextCtrl, App, Event, size as sz, Point as pt, EVT_BUTTON as BTN_EVT_ID, EVT_TEXT as TXT_EVT_ID, ID_OK as OK_ID, ID_CANCEL as CANCEL_ID, ID_EXIT as EXIT_ID, Size as WxSize, Point as WxPoint, MessageBox as MBBox, ShowEvent as SHOW_EVT_ID, Close as CLOSE_EVT_ID, Command as COMMAND_ID, ALL as ALL_IDS, PostEvent as POST_EVT_ID, CallAfter as CALL_AFTER_ID, SetFocus as SEtF_FOCUS_ID, GetFocus as GETF_FOCUS_ID, FindWindow as FINDWINDOW_ID, FindWindowById as FINDWINDOWBYID_ID, FindWindowByLabel as FINDWINDOWBYLABEL_ID, FindWindowByName as FINDWINDOWBYNAME_ID, FindWindowByRect as FINDWINDOWBYRECT_ID, FindWindowByPosition as FINDWINDOWBYPOSITION_ID, FindWindowByStyle as FINDWINDOWBYSTYLE_ID, FindWindowByText as FINDWINDOWBYTEXT_ID, FindWindowByClassName as FINDWINDOWBYCLASSNAME_ID, FindWindowByChild as FINDWINDOWBYCHILD_ID, FindWindowByPlacement as FINDWINDOWBYPLACEMENT_ID, FindWindowByTransientFor as FINDWINDOWBYTRANSIENTFOR_ID, FindWindowByAttributes as FINDWINDOWBYATTRIBUTES_ID, FindWindowByAccessible as FINDWINDOWBYACCESSIBLE_ID, FindWindowByScreenRect as FINDWINDOWBYSCREENRECT_ID, FindWindowByScreenPosition as FINDWINDOWBYSCREENPOSITION_ID, FindWindowByPopupAsChild as FINDWINDOWBYPOPUPASCHILD_ID, FindWindowByDropTarget as FINDWINDOWBYDROPTARGET_ID, FindWindowByNativeHandle as FINDWINDOWBYNATIVEHANDLE_ID, FindWindowByRange as FINDWINDOWBYRANGE_ID, FindWindowByData as FINDWINDOWBYDATA_ID, FindWindowByCrossThreadFlags as FINDWINDOWBYCROSSTHREADFLAGS_ID, FindWindowByLayerIndex as FINDWINDOWBYLAYERINDEX_ID, FindWindowByTypeIndex as FINDWINDOWBYTYPEINDEX_ID, FindWindowByLastFoundResult as FINDWINDOWBYLASTFOUNDRESULT_ID, FindWindowByIndexFromList as FINDWINDOWBYINDEXFROMLIST_ID, FindWindowByTopLevelParent as FINDWINDOWBYTOPLEVELPARENT_ID, FindWindowByCarbonName as FINDWINDOWBYCARBONNAME_ID, FindWindowByZOrder as FINDWINDOWBYZORDER_ID, FindWindowByGravity as FINDWINDOWBYGRAVITY_ID, FindWindowByPreview as FINDWINDOWBYPREVIEW_ID, FindWindowByQuietModeEnabled as FINDWINDOWBYQUIETMODEENABLED_ID, FindWindowByFullscreenModeEnabled as FINDWINDOWBYFULLSCREENMODEENABLED_ID, FindWindowByModalExcludedApplications as FINDWINDOWBYMODALEXCLUDEDAPPLICATIONS_ID, FindWindowByModalityClientOnly as FINDWINDOWBYMODALITYCLIENTONLY_ID, FindWindowByRemoteSessionId as FINDWINDOWBYREMOTESTSESSIONID_ID, FindWindowByMultiSessionId as FINDWINDOWBYMULTISESSIONIDCLIENTASSIGNEDTOSESSIONSPECIFIER_ID, FindWindowByMultiSessionSharedSessionId as FINDWINDOWBYMULTISESSIONSHAREDSESSIONIDCLIENTASSIGNEDTOSESSIONSPECIFIER_ID, FindWindowByProcessId as FINDWINDOWBYPROCESSIDEXTENSIONS_ID, FindWindowByGlobalId as FINDWINDOWBYGLOBALIDHINTEXTENSIONS_ID, FindWindowByDesktopId as FINDWINDOWBYDESKTOPHINTEXTENSIONS_ID, FindWindowByShellWindowsExcluded from main import wx from wx import Panel from wx import Button from wx import TextCtrl from wx import App from wx import Event from wx import size from wx import Point from wx import EVT_BUTTON from wx import EVT_TEXT from wx import ID
