qt nsis脚本用代码生成

你可以使用Qt Installer Framework来生成NSIS脚本。以下是一些基本步骤：

1. 安装Qt Installer Framework
2. 创建一个安装程序项目
3. 在项目中定义所需的组件和安装程序页面
4. 生成安装程序脚本

下面是一个示例脚本，用于创建一个基本的安装程序：

# Installer script for My Application

# Include the NSIS header file
!include "MUI2.nsh"

# Define the application name and version
!define APPLICATION_NAME "My Application"
!define APPLICATION_VERSION "1.0"

# Define the installation path
InstallDir "$PROGRAMFILES\${APPLICATION_NAME}"

# Define the components to install
!insertmacro MUI_PAGE_COMPONENTS
!insertmacro MUI_PAGE_DIRECTORY

# Define the start menu shortcut
!define MUI_STARTMENUPAGE_REGISTRY_ROOT "HKCU"
!define MUI_STARTMENUPAGE_REGISTRY_KEY "Software\${APPLICATION_NAME}"
!define MUI_STARTMENUPAGE_REGISTRY_VALUENAME "StartMenuShortcut"
!insertmacro MUI_STARTMENUPAGE

# Define the finish page
!insertmacro MUI_PAGE_FINISH

# Define the uninstaller page
!insertmacro MUI_UNPAGE_CONFIRM
!insertmacro MUI_UNPAGE_INSTFILES

# Define the installation section
Section
    # Set the installation path
    SetOutPath "$INSTDIR"

    # Copy files to the installation directory
    File "MyApplication.exe"
    File "Readme.txt"

    # Create start menu shortcut
    CreateDirectory "$SMPROGRAMS\${APPLICATION_NAME}"
    CreateShortCut "$SMPROGRAMS\${APPLICATION_NAME}\${APPLICATION_NAME}.lnk" "$INSTDIR\MyApplication.exe"

你可以根据需要修改此脚本，并使用Qt Installer Framework生成NSIS安装程序。
