学python3编程gui用wxpython界面库示例

linux下安装需要先安装依赖

sudo apt-get install libgtk-3-dev -y
sudo apt-get install freeglut3-dev libgstreamer-plugins-base1.0-dev -y

sudo pip install wxpython

如果有些依赖版本不匹配可能太高也不行，可能失败，需要卸载装上特定低版本

sudo pip uninstall numpy

sudo pip install numpy=1.16

代码写界面太累，照旧找到可视化设计界面工具wxformbuilder

https://github.com/wxFormBuilder/wxFormBuilder/releases

linux下可以下载flatpak格式，源代码编译安装不易成功，依赖太多了

sudo apt install flatpak flatpak-builder
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak install flathub org.freedesktop.Platform//18.08

flatpak install flathub org.wxformbuilder.wxFormBuilder

也可下载后本地安装，就是网址太慢了

https://github.com/wxFormBuilder/wxFormBuilder/releases/download/v3.9.0/wxformbuilder.flatpak

最后找了一个浏览器插件 Free Download GitHub Release Downloads CRX 1.3插件， 专门下载github release的文件，到了github页面点击下载链接，能得到真实网址，然后成功了，也不确定是不是这个插件起作用了

如果下载到了不用到flathub安装，本地安装：

flatpak install ./wxformbuilder.flatpak

flatpak run org.wxformbuilder.wxFormBuilder # 运行软件

新建界面文件时先建外框frame，然后加入布局器，然后控件，界面文字可能不好输入中文，这些问题不大，生成py文件，引入到py调用里
在调用方里初始化各个控件显示文字，实现虚函数方法

如上就是生成的test1.py界面代码

下面附上调用代码

#!/usr/bin/python3

import wx
# 导入test1.py中内容
import test1


# 创建mainWin类并传入 test1.MyFrame1
class mainWin(test1.MyFrame1):
    def __init__(self,parent):
        test1.MyFrame1.__init__(self,parent)
        self.path.SetLabelText("路径")
        self.filename.SetValue("/home/qzc/Documents/pythonbook/pythonbook.txt")
        self.SetTitle("简单看文件")
        self.m_btn_exit.SetLabelText("退出")
        self.m_btn_open.SetLabelText("加载")

        # 首先，咱们从刚刚源文件中将主窗体继承下来.就是修改过name属性的主窗体咯。
    def load(self, event):
        file = open(self.filename.GetValue())
        self.contents.SetValue(file.read())
        file.close

    def save(self, event):
        file = open(self.filename.GetValue(), 'w')
        file.write(self.contents.GetValue())
        file.close()

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


if __name__ == '__main__':
    # 下面是使用wxPython的固定用法
    app = wx.App()

    main_win = mainWin(None)
    main_win.Show()

    app.MainLoop()
