开机自启动是一个常用需求,本文探讨之..
windows平台
修改注册表: 不推荐
- 有些杀软拦截
- 启动时机较早(当然是启动后),可能有些COM之类的接口调用会失败
使用计划任务自启动: 不推荐
- 不利于编程
- 可设置性最高(甚至不用登陆windows就可以运行)
使用快捷方式启动: 推荐
下面只介绍在方法三的编程
3.1 简单启动
使用QStandardPaths + QFile::link 可以完成该目的
需要注意的是在XP和非XP系统的快捷方式路径不同(分别为Startup和启动)

#ifdef Q_OS_WIN
QString startUpPath = QString("%1/%2")

.arg("Startup");
QDir dir;
if(!dir.exists(startUpPath)){

.arg(startUpPath)
.arg(linkName);
if(autoRun){
if(QFile::symLinkTarget(linkFull) != exeName){
QFile::link(exeName, linkFull);
}
}
else{
if(QFile::exists(linkFull)){
QFile::remove(linkFull);
}
}
#else
#endif

3.2 带参数的启动
上面的方式可用于简单的开机自启,但是如果需要创建带参数的快捷方式就鸡鸡了,查看Qt的源代码qfsfileengine_win.cpp中的bool QFSFileEngine::link(const QString &newName)函数, 发现官方偷懒了没办法自己动手吧…
在pro文件中添加
win32{
LIBS += -lole32
LIBS += -luuid
}

Linux平台
这个和windows平台类似(参考了ubuntu下的Stacer软件)
