需求:
给qt编写的桌面软件制作安装向导,检测安装路径,覆盖安装
软件主程序下有OpenVino、python 2个子模块,可选安装
安装Qt IFW

目录结构说明
总体结构
建立目录结构如下:
-
HyperVisionIFW:项目名称
-
docs:存放文档
-
V0.4.2: 区分不同版本(由D:QtQtIFW-4.2.0examplesstartmenu修改而来)
config目录
config.xml 必要文件
<?xml version="1.0" encoding="UTF-8"?>
<Installer>
<Name>HyperVision</Name>
<Version>0.4.2</Version>
<Title>HyperVision安装向导</Title>

字段含义见:Configuration File | Qt Installer Framework Manual
style.qss 界面样式表
QWidget
{

}
packages目录
根据自己项目实际情况划分模块
root.openvino表示为root的子模块
组件名称 | 含义 |
---|---|
root | 主程序 |
root.openvino | 深度学习工具库 |
root.python | python解释器 |
每个组件下包含data、meta 2个文件夹
data下存放需要打包的exe、dll、其他文件
meta下存放安装脚本、UI、组件配置信息
对应界面如下:
root
-
data
./data/script/uninstallscript.qs 卸载脚本,自动点击maintenancetool界面next按钮
// 卸载脚本:如果程序已安装,则会调用 maintenance 工具,自动进行卸载。
function Controller()
{
gui.clickButton(buttons.NextButton);
gui.clickButton(buttons.NextButton);
// 连接信号槽
installer.uninstallationFinished.connect(this, this.uninstallationFinished);
}
// 当卸载完成时,触发
Controller.prototype.uninstallationFinished = function()
{
gui.clickButton(buttons.NextButton);
}
// 与完成页面上的部件交互
Controller.prototype.FinishedPageCallback = function()
{
gui.clickButton(buttons.FinishButton);
}

打包安装包
编写一个运行脚本 build.bat
D:/Qt/QtIFW-4.2.0/bin/binarycreator.exe -c ./config/config.xml -p ./packages hypervision-windows-x86-0.4.2.0222.exe -v
pause
-c 指定config路径
-p 指定包路径
双击build.bat
等待运行完毕后,生成hypervision-windows-x86-0.4.2.0222.exe
